Description
Background
[0001] The present disclosure relates generally to techniques for noise cancellation and, more particularly, for preemptive noise convergence for noise cancellation.
[0002] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.
[0003] Many electronic devices employ voice-related features that involve recording and/or analyzing a user's voice. Voice recognition features, for example, may analyze a voice command spoken by a user to perform a task related to the command. Similarly, voice note recording features may record voice notes spoken by the user. However, when a user speaks into a microphone of an electronic device, ambient sounds, or background noise, may be obtained by the microphone at the same time. These ambient sounds may obscure the user's voice and, in some cases, may impede the proper functioning of a voice-related feature of the electronic device.
Summary

It should be understood that these aspects are presented merely to provide the reader with a brief summary of these certain embodiments and that these aspects are not intended to limit the scope of this disclosure.

Detailed Description of Specific Embodiments
[0021] One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.
[0022] Present embodiments relate to techniques for determining a noise profile for voice cancellation used in combination with voice-related features of electronic devices. As used herein, the term “noise profile” generally may refer to information relating to noise in a signal, such as ambient sounds in an audio signal, which may be employed to exclude such noise from another signal. For example, using the techniques described herein, a noise profile may be employed to filter ambient sounds from a voice command for a voice recognition feature, to isolate a user's voice for recording voice notes, to isolate a subject's voice for recording video, to enhance the quality of sound for a telephone feature, and so forth. Rather than attempt to identify noise at the time when a user activates or uses such a voice-related feature, the electronic device may remove ambient sounds using a noise profile developed from a prior recording of ambient sounds. As used herein, the term “voice-related feature” may refer to any functionality of an electronic device, which may be implemented in hardware or software, that may at least partially filter ambient sounds from an audio signal that may include voice audio and the ambient sounds. Among other things, such a voice-related feature may include voice recognition software that may receive voice commands from a user and, after filtering away ambient sounds, may perform various tasks based on the voice command. By way of example, voice recognition software may include the Voice Control application by Apple Inc.
[0023] In particular, because attempting to identify noise after a user has begun to speak may result in delays or a misidentification of ambient noise, an electronic device employing the techniques disclosed herein may periodically sample ambient sounds and construct a noise profile based on such ambient sounds when the voice-related feature is not in use. Additionally or alternatively, the electronic device may sample ambient sounds based on a stimulus (e.g., activation of a non-voice-related feature, initialization of the electronic device, navigation to the voice-related feature, a change in the context of use of the electronic device, and/or when another person is speaking on a telephone feature of the electronic device). Moreover, in some embodiments, the electronic device may assess a current context of use of the electronic device at the time the ambient sounds are sampled and when the noise profile is subsequently constructed. By way of example, the electronic device may consider a time, a current location of the electronic device, an amount of ambient light surrounding the electronic device, an amount of motion of the electronic device, and/or a volume level of ambient sounds.
[0024] A general description of suitable electronic devices for performing the presently disclosed techniques is provided below. In particular, FIG. 1 is a block diagram depicting various components that may be present in an electronic device suitable for use with the present techniques. FIG. 2 represents one example of a suitable electronic device, which may be, as illustrated, a handheld electronic device having image capture circuitry, motion-sensing circuitry, and video processing capabilities.
[0025] Turning first to FIG. 1 , an electronic device 10 for performing the presently disclosed techniques may include, among other things, a central processing unit (CPU) 12 and/or other processors, memory 14, nonvolatile storage 16, a display 18, an internal clock 20, location-sensing circuitry 22, an input/output (I/O) interface 24, network interfaces 26, image capture circuitry 28, accelerometers/magnetometer 30, and a microphone 32. The various functional blocks shown in FIG. 1 may include hardware elements (including circuitry), software elements (including computer code stored on a computer-readable medium) or a combination of both hardware and software elements. It should further be noted that FIG. 1 is merely one example of a particular implementation and is intended to illustrate the types of components that may be present in electronic device 10.
[0026] By way of example, the electronic device 10 may represent a block diagram of the handheld device depicted in FIG. 2 or similar devices. Additionally or alternatively, the electronic device 10 may represent a system of electronic devices with certain characteristics. For example, a first electronic device may include at least a microphone 32, which may provide audio to a second electronic device including the CPU 12 and other data processing circuitry. It should be noted that the data processing circuitry may be embodied wholly or in part as software, firmware, hardware or any combination thereof. Furthermore the data processing circuitry may be a single contained processing module or may be incorporated wholly or partially within any of the other elements within electronic device 10. The data processing circuitry may also be partially embodied within electronic device 10 and partially embodied within another electronic device wired or wirelessly connected to device 10. Finally, the data processing circuitry may be wholly implemented within another device wired or wirelessly connected to device 10. As a non-limiting example, data processing circuitry might be embodied within a headset in connection with device 10.
[0027] In the electronic device 10 of FIG. 1 , the CPU 12 and/or other data processing circuitry may be operably coupled with the memory 14 and the nonvolatile memory 16 to perform various algorithms for carrying out the presently disclosed techniques. Such programs or instructions executed by the processor(s) 12 may be stored in any suitable manufacture that includes one or more tangible, computer-readable media at least collectively storing the instructions or routines, such as the memory 14 and the nonvolatile storage 16. Also, programs (e.g., an operating system) encoded on such a computer program product may also include instructions that may be executed by the processor(s) 12 to enable the electronic device 10 to provide various functionalities, including those described herein. The display 18 may be a touch-screen display, which may enable users to interact with a user interface of the electronic device 10. The internal clock 20 may track time and/or date. The location-sensing circuitry 22 may represent device capabilities for determining the relative or absolute location of electronic device 10. By way of example, the location-sensing circuitry 22 may represent Global Positioning System (GPS) circuitry, algorithms for estimating location based on proximate wireless networks, such as local Wi-Fi networks, and so forth.
[0028] The I/O interface 24 may enable electronic device 10 to interface with various other electronic devices, as may the network interfaces 26. The network interfaces 26 may include, for example, interfaces for a personal area network (PAN), such as a Bluetooth network, for a local area network (LAN), such as an 802.11x Wi-Fi network, and/or for a wide area network (WAN), such as a 3G cellular network. Through the network interfaces 26, the electronic device 10 may interface with a wireless headset that includes a microphone 32. The image capture circuitry 28 may enable image and/or video capture, and the accelerometers/magnetometer 30 may observe the movement and/or a relative orientation of the electronic device 10.
[0029] When employed in connection with a voice-related feature of the electronic device 10, such as a voice recognition software application, the microphone 32 may obtain an audio signal of a user's voice and other ambient sounds. The CPU 12 may process the audio signal to exclude most ambient sounds using a previously-determined noise profile. As described in greater detail below, the noise profile may be determined prior to the activation of the voice-related feature of the electronic device 10, based on a recording of the ambient sounds. Although the microphone 32 generally may be inactive, the microphone 32 may periodically awaken, or may awaken after a stimulus, to record the ambient sounds when the user is not speaking.
[0030] FIG. 2 depicts a handheld device 34, which represents one embodiment of electronic device 10. The handheld device 34 may represent, for example, a portable phone, a media player, a personal data organizer, a handheld game platform, or any combination of such devices. By way of example, the handheld device 34 may be a model of an iPod® or iPhone® available from Apple Inc. of Cupertino, Calif.
[0031] The handheld device 34 may include an enclosure 36 to protect interior components from physical damage and to shield them from electromagnetic interference. The enclosure 36 may surround the display 18, which may display indicator icons 38. Such indicator icons 38 may indicate, among other things, a cellular signal strength, Bluetooth connection, and/or battery life. The I/O interfaces 24 may open through the enclosure 36 and may include, for example, a proprietary I/O port from Apple Inc. to connect to external devices. As indicated in FIG. 2 , the reverse side of the handheld device 34 may include the image capture circuitry 28 and, in certain embodiments, an outward-facing microphone 32. As described below, the outward-facing microphone 32 may be used to capture audio of ambient sounds even while the handheld device 34 is in use.
[0032] User input structures 40, 42, 44, and 46, in combination with the display 18, may allow a user to control the handheld device 34. For example, the input structure 40 may activate or deactivate the handheld device 34, the input structure 42 may navigate user interface 20 to a home screen, a user-configurable application screen, and/or activate a voice-recognition feature of the handheld device 34, the input structures 44 may provide volume control, and the input structure 46 may toggle between vibrate and ring modes. The microphones 32 may obtain a user's voice for various voice-related features, and a speaker 48 may enable audio playback and/or certain phone capabilities. Headphone input 50 may provide a connection to external speakers and/or headphones.
[0033] As illustrated in FIG. 2 , a wired headset 52 may connect to the handheld device 34 via the headphone input 50. The wired headset 52 may include two speakers 48 and a microphone 32. The microphone 32 may enable a user to speak into the handheld device 34 in the same manner as the microphones 32 located on the handheld device 34. In some embodiments, a button near the microphone 32 may cause the microphone 32 to awaken and/or may cause a voice-related feature of the handheld device 34 to activate. A wireless headset 54 may similarly connect to the handheld device 34 via a wireless interface (e.g., a Bluetooth interface) of the network interfaces 26. Like the wired headset 52, the wireless headset 54 may also include a speaker 48 and a microphone 32. Also, in some embodiments, a button near the microphone 32 may cause the microphone 32 to awaken and/or may cause a voice-related feature of the handheld device 34 to activate. Additionally or alternatively, a standalone microphone 32 (not shown), which may lack an integrated speaker 48, may interface with the handheld device 34 via the headphone input 50 or via one of the network interfaces 26.
[0034] A user may use a voice-related feature of the electronic device 10, such as a voice-recognition feature, in a variety of contexts. FIG. 3 illustrates many such contexts 56 in which the electronic device 10, depicted as the handheld device 34, may receive a voice audio signal 58 from the user and ambient sounds 60 while performing a voice-related feature. By way of example, the voice-related feature of the electronic device 10 may include, for example, a voice recognition feature, a voice note recording feature, a video recording feature, and/or a telephone feature. The voice-related feature may be implemented on the electronic device 10 in software carried out by the CPU 12 or other processors, and/or may be implemented in specialized hardware.
[0035] To activate the voice-related feature on the electronic device 10, the user may navigate to an icon representing the voice-related feature or may press one or more of the input structures 40-46. For example, to activate a voice-recognition feature of the handheld device 34, the user may press down the input structure 42 for approximately two seconds. Thereafter, the user may speak the voice audio signal 58, which may enter the microphone 32 of the electronic device 10. At approximately the same time, however, ambient sounds 60 may also enter the microphone 32. Based on a previously-determined noise profile, the electronic device 10 may filter away the ambient sounds 60 such that the voice audio signal 58 is largely free of such noise.
[0036] The ambient sounds 60 may vary depending on the context 56 in which the electronic device 10 is being used. The various contexts 56 in which the voice-related feature may be used may include at home 62, in the office 64, at the gym 66, on a busy street 68, in a car 70, at a sporting event 72, at a restaurant 74, and at a party 76, among others. As should be appreciated, the typical ambient sounds 60 that occur on a busy street 68 may differ greatly from the typical ambient sounds 60 that occur at home 62 or in a car 70.
[0037] Because the character of the ambient sounds 60 may vary from context 56 to context 56, a single generic noise profile may not effectively eliminate the ambient sounds 60 in all of the contexts 56. Rather, as described in greater detail below, the electronic device 10 may filter the ambient sounds 60 using a noise profile determined from a prior recording of the ambient sounds 60 that occurs before the user activates the voice-related feature of the electronic device 10. Additionally, each of the contexts 56 may occur at certain locations and times, with varying amounts of electronic device 10 motion and ambient light, and/or with various volume levels of the voice signal 58 and the ambient sounds 60. As such, in some embodiments, the electronic device 10 may filter the ambient sounds 60 using a noise profile previously determined in a similar context 56 based on the time, location, motion, ambient light, and/or volume level.
[0038] FIG. 4 is a flowchart 78 representing an embodiment of a method for isolating the voice audio signal 58 from the ambient sounds 60 when a voice-related feature of the electronic device 10 is used. In a first step 80, a user may activate the voice-related feature of the electronic device 10. Depending on the configuration of the electronic device 10, step 80 may include navigating to a voice-related feature icon, holding down the button 42, or pressing or holding a button on the wired headset 52 or wireless headset 54.
[0039] In step 82, the electronic device 10 may receive audio from the microphone 32 that is currently active. The active microphone 32 may be located, for example, on the handheld device 34, the wired headset 52, or the wireless headset 54. In step 84, a most-recently-determined noise profile may be recalled from the memory 14 or nonvolatile storage 16. This noise profile may represent a noise profile determined based on a recent observation of the ambient sounds 60 prior to the activation of the voice-related feature in step 80.
[0040] In step 86, the ambient sounds 60 may be filtered out of the audio obtained in step 82, substantially isolating the voice audio signal 58. Thereafter, the voice audio signal 58 may be employed by the voice-related feature. By way of example, when the voice-related feature is a voice recognition feature, the electronic device 10 typically may subsequently analyze the voice audio signal 58 to ascertain a voice command. When the voice-related feature is a voice note recording feature, voice notes may be recorded with reduced background noise.
[0041] FIG. 5 is a flow diagram 92 that illustrates a manner of performing the method of FIG. 4 . As shown in the flow diagram 92, the active microphone 32 may receive the voice audio signal 58 as well as the ambient sounds 60. The active microphone 32 and/or related circuitry may, in some embodiments, digitize and/or compress the obtained audio to produce a digital audio signal 94. A filter 97, which may be implemented using hardware, software, firmware, or a combination thereof, and which may include the CPU 12 and/or other processors, may receive the digital audio signal 94. Based on a noise profile 96 received from memory 14 and/or the nonvolatile storage 16, the filter 97 may filter the ambient sounds 60 out of the digital audio signal 94. When the ambient sounds 60 have been at least partially filtered from the digital audio signal 94, an isolated voice signal 98 may result.
[0042] Because a generic noise profile may not sufficiently isolate the ambient sounds 60 found in the various contexts 56 in which voice-related features may be used, and because determining the noise profile after a voice-related feature has been activated, the electronic device 10 may periodically determine the noise profile by sampling the ambient sounds 60 when the voice-related feature is not in use and/or using the outward-facing microphone 32. A flowchart 100, illustrated in FIG. 6 , represents an embodiment of such a method for periodically determining a current noise profile 96. First step 102 may occur while a voice-related feature is not currently in use, or may involve the use of an outward-facing microphone 32 of the electronic device 10, such that the microphone 32 will less likely pick up sounds of the user's voice and will more likely pick up ambient sounds 60. In step 102, the electronic device 10 may periodically awaken a microphone 32 on the electronic device 10, the wired headset 52, or the wireless headset 54 after a period of inactivity. As described below with reference to FIG. 8 , the length of the period of inactivity of the microphone 32, occurring prior to step 102, may vary depending on a variety of factors. By way of example, the period of inactivity may be chosen such that the microphone 32 is activated every 5 seconds, 10 seconds, 20 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, 20 minutes, 30 minutes, 1 hour, or 2 hours, and so forth.
[0043] In step 104, the active microphone 32 may obtain ambient sounds by sampling the ambient sounds 60 for a period of time. As described below with reference to FIG. 9 , the length of the sampling period may vary depending on a variety of factors. By way of example, the sampling period may be chosen such that the ambient sounds 60 are sampled for 1 second, 2 seconds, 5 seconds, 10 seconds, 20 seconds, or 30 seconds, 1 minute and so forth. The ambient sounds 60 sampled in step 104 may provide a basis for determining, in step 106, a current noise profile 96. The determination of the noise profile 96 of step 106 may take place in the electronic device 10 using any noise convergence technique, such that the determined current noise profile 96 may later be used to filter out ambient sounds 60, in the manners described above with reference to FIGS. 4 and 5 . In step 108, the electronic device 10 may optionally store the newly determined noise profile 96 in memory 14 or nonvolatile storage 16.
[0044] A flow diagram 110, representing a manner of performing the method of FIG. 6 , is illustrated in FIG. 7 . In the flow diagram 110, when the electronic device 10 periodically awakens the active microphone 32 when a voice-related feature is not in use, or when the active microphone 32 is an outward-facing microphone 32, primarily only ambient sounds 60 may be picked up in the microphone 32 to form the audio signal 94. The CPU 12 and/or any suitable data processing circuitry of the electronic device 10 may receive the digital audio signal 94, converging the ambient sounds 60 of the digital audio signal 94 to a noise profile 96 that may later be used to filter out the recently-obtained ambient sounds 60. The noise profile 96 may be stored in memory 14 or nonvolatile storage 16.
[0045] As mentioned above with reference to the flowchart 100 of FIG. 6 , the microphone 32 may not remain active at all times, but rather may activate after a period of inactivity to conserve resources of the electronic device 10. FIG. 8 illustrates a schematic diagram 112 representing various activation period factors 114 for determining the period of inactivity between times in which the microphone 32 may be activated. Based on one or more of the activation period factors 114, the electronic device 10 may determine the period of inactivity at the time the current noise profile 96 is determined, every few times the current noise profile 96 is determined, or at other times. In general, the activation period factors 114 may balance how likely a voice-related feature is to be activated by a user and the use of resources for determining the noise profile 96 for the voice-related feature.
[0046] A first factor 116 of the activation period factors 114 may be a current mode of the electronic device 10. By way of example, the electronic device 10 may be actively in use, may be inactive or in a sleep mode, and/or may be operating in a mode with reduced functionality, such as “airplane mode.” The factor 116 may weigh in favor of a shorter period of inactivity if the electronic device 10 is actively in use, and a voice-related feature is thus more likely to be activated by the user. The factor 116 may weigh in favor of a longer period of inactivity if the electronic device 10 is inactive or operating in a mode of reduced functionality.
[0047] A second factor 118 of the activation period factors 114 may be a current state of a power supply of the electronic device 10. By way of example, if the electronic device 10 is currently being charged, a user may be less likely to use a voice-related feature of the electronic device 10. Under such conditions, the factor 118 may weigh in favor of a longer period of inactivity. Alternatively, because the electronic device 10 may effectively have an unlimited supply of power, the factor 118 may instead weigh in favor of a shorter period of inactivity.
[0048] When the electronic device 10 is not currently being charged, the amount of remaining battery life may be considered. For example, when the battery life of the electronic device 10 remains high, the factor 118 may weigh in favor of a relatively shorter period of inactivity because the additional power needed to activate the microphone and to determine the noise profile may be justified. When the battery life of the electronic device 10 is relatively low, the factor 118 may weigh in favor of a relatively longer period of inactivity to conserve the remaining battery power.
[0049] A third factor 120 of the activation period factors 114 may be an amount of recent motion of the electronic device 10, as detected by the accelerometers/magnetometer 30. If very little motion is detected, the factor 120 may weigh in favor of a longer period of inactivity, as the electronic device 10 may have been set down by the user and, accordingly, a voice-related feature of the electronic device 10 may be less likely to be used. On the other hand, if a significant amount of motion is detected, the factor 120 may weigh in favor of a shorter period of inactivity, as the electronic device 10 is likely being carried by the user and, accordingly, a voice-related feature of the electronic device 10 may be more likely to be used.
[0050] A fourth factor 122 of the activation period factors 114 may be the variability of recently-determined noise profiles 96. Specifically, if a recently determined noise profile 96 is very similar to previously-determined noise profiles 96, further noise profiles 96 that are subsequently determined may likely provide little benefit over the previously-determined noise profiles 96. Under such conditions, the factor 122 may weigh in favor of a longer period inactivity, because additional sampling by the microphone 32 may be less likely to obtain ambient sounds 60 that would produce a significantly different noise profile 96. If recently-determined noise profiles 96 vary greatly, however, the factor 122 may weigh in favor of a shorter period of inactivity.
[0051] A fifth factor 124 of the activation period factors 114 may be the current location of the electronic device 10. If the user has previously used, or frequently uses, a voice-related feature of the electronic device 10 at the current location (e.g., at home), as determined by the location-sensing circuitry 22 or based on a wireless network currently visible to the network interfaces 26, the factor 124 may weigh in favor of a shorter period of inactivity. If not, the factor 124 may weigh in favor of a longer period of inactivity.
[0052] Similarly, a sixth factor 126 of the activation period factors 114 may be a history of voice-related feature use on the electronic device 10. By way of example, based on the history of use of the voice-related feature, the factor 126 may weigh in favor of a shorter period of inactivity at times of the day when the voice-related feature of the electronic device 10 is frequently used. The factor 126 may weigh in favor of a longer period of inactivity at times of the day when the voice-related feature is rarely used.
[0053] As noted above, the period of time in which the microphone 32 may sample the ambient sounds 60 in step 104 of the flowchart 100 may vary. The particular length of the sampling period may vary depending on a variety of factors, as illustrated in FIG. 9 . In FIG. 9 , a schematic diagram 130 represents several sampling time factors 132. The sampling time factors 132 may be used by the electronic device 10 to determine the sampling time at the time the noise profile 96 is determined, every few times the noise profile 96 is determined, or at other times. In general, the sampling time factors 132 may balance how likely a voice-related feature is to be activated by a user and the use of resources for determining the noise profile 96 for the voice-related feature.
[0054] A first factor 134 of the sampling time factors 132 may be an error rate that occurs when a voice-related feature is used. Certain voice-related features, such as voice-recognition features, may incorrectly identify a voice signal 98 if the ambient sounds 60 are not sufficiently filtered during noise cancellation. The error rate of such a voice-related feature may be stored and considered as the factor 134. As such, the factor 134 may weigh in favor of a longer sampling time as the error rate increases.
[0055] A second factor 136 of the sampling time factors 132 may be an amount of time required to converge the ambient sounds 60 in the digital audio signal 94 to obtain the noise profile 96. The factor 136 may weigh in favor of a sampling time that corresponds, longer or shorter, with recent convergence times.
[0056] A third factor 138 of the sampling time factors 132 may be a comparison of the digital audio signal 94 from the active microphone 32 to prior recordings of the ambient sounds 60 or a prior noise profile 96. By way of example, the factor 138 may weigh in favor of a shorter sampling time if the digital audio signal 94 appears to be very similar to previously-recorded ambient sounds 60 or prior noise profiles 96. In other words, if newly recorded ambient sounds 60 would simply result in a very similar noise profile 96, the sampling time 132 may be reduced or cut short.
[0057] A fourth factor 140 of the sampling time factors 132 may relate to whether other noise profiles 96 have been stored, which were previously obtained in the same or similar context 56 in which the electronic device is currently being used. As described below with reference to FIGS. 10-13 , certain embodiments of the techniques disclosed herein may involve observing and storing information relating to a current context 56 of use of the electronic device 10 with noise profiles 96 as they are determined. The factor 140 may weigh in favor of a shorter sampling time when other noise profiles 96 have already been obtained from a similar context 56.
[0058] FIGS. 10-13 relate to manners of determining a contextual noise profile and, at a later time, using the contextual noise profile in the proper context 56. Turning first to FIG. 10 , a flowchart 150 represents an embodiment of a method for periodically determining a contextual noise profile. Steps 152-156 may be performed at substantially the same manner of steps 102-106 of the flowchart 100 of FIG. 6 . Thus, after step 156, a noise profile may be determined based on the ambient sounds 60.
[0059] In step 158, the electronic device 10 may determine its current context of use by ascertaining the time, the location, amount of ambient light, amount of motion, and/or volume of ambient sounds 60 currently associated with the electronic device 10. In some embodiments, more or fewer such indicators of the current context 56 may be considered. In step 160, the noise profile determined in step 156 and the contextual indicators assessed in step 158 may be associated. This may result in a contextual noise profile that may be identified for later use when the electronic device 10 is in the same or a similar context 56. In step 162, the contextual noise profile may be stored in memory 14 or nonvolatile storage 16.
[0060] FIG. 11 is a flow diagram 164 representing a manner of performing the method of FIG. 10 . As shown in the flow diagram 164, ambient sounds 60 may be periodically detected by the active microphone 32 and converted to a digital audio signal 94. A data processing unit such as CPU 12 may use the digital audio signal 94 to determine a noise profile associated with the ambient sounds 60. Additionally, the CPU 12 may receive a time signal 166 from the clock 20, a location signal 168 from the location-sensing circuitry 22, an ambient light signal 170 from the image-capture circuitry 28, and/or a motion and/or orientation signal 172 from the accelerometer/magnetometer 30. The signals 166-172, as well as a determination of the volume level of the digital audio signal 94, may relate to a current context of use of the electronic device 10. Since the various contexts 56 in which the electronic device may be used may have recognizable times, locations, ambient amounts of light, amounts of motion, and volume levels, the signals 166-172 may enable the CPU 12 to create a contextual noise profile 174 that generally may represent the ambient sounds 60 found at other similar times, locations, ambient amounts of light, amounts of motion, and volume levels. By way of example, a user may commute from home to work each day in a car between 8:00 and 9:00 AM. A contextual noise profile 174 obtained one day at this time likely may represent ambient sounds 60 that may occur during another day at the same time. Thereafter, the contextual noise profile 174 may be stored in memory 14 and/or nonvolatile storage 16. In some embodiments, the contextual noise profile 174 may be stored in a database or similar data structure.
[0061] At a later time, the contextual noise profile 174 may be used for noise-cancellation when a user activates a voice-related feature in a similar context 56, as described in a flowchart 176 of FIG. 12 . In the flowchart 176, steps 178 and 180 may be substantially the same as steps 80 and 82 of the flowchart 78 of FIG. 4 . In step 182, the electronic device 10 may assess the current context 56 of the electronic device by ascertaining the current time, location, ambient amount of light, amount of motion, and/or the volume of ambient sounds 60 in the digital audio signal 94. In step 184, the electronic device 10 may select a contextual noise profile 174 that matches the current context 56 ascertained in step 182. In step 186, the electronic device 10 may filter away the ambient sounds 60 based on the contextual noise profile to isolate the user's voice.
[0062] FIG. 13 is a flow diagram 188 illustrating a manner of performing the method described in FIG. 12 . As shown in the flow diagram 188, when a user elects to use a voice-related feature, the active microphone 32 may take in the voice audio signal 58 along with various ambient sounds 60. The ambient sounds 60 may be converted into an audio signal 94 and transmitted to the filter 97, which may be implemented using hardware, software, firmware, or a combination thereof, and which may include the CPU 12 and/or other processors. Additionally, the filter 97 may receive a time signal 166 from the clock 20, a location signal 168 from the location-sensing circuitry 22, and ambient light signal 170, from the image capture circuitry 28, and a motion signal 172 from the accelerometer/magnetometer 30. Based on the signals 166-172, as well as the volume of the digital audio signal 94, the filter 97 may select a contextual noise profile 174 from the memory 14 or nonvolatile storage 16 that corresponds to a similar context of use 56. To continue with the example mentioned above, if a user commutes from home to work each day in a car between 8:00 and 9:00 AM, and the time is currently 8:30 AM, the filter 97 may select a contextual noise profile 174 previously obtained around the same time, and therefore likely when the user was commuting to work. Using the contextual noise profile 174, the filter 97 may filter out the ambient sounds 60 from the audio signal 94, producing a voice audio signal 98.
[0063] As described above, a noise profile 96 and/or 174 may be determined on a periodic basis, before a user activates a voice-related feature of the electronic device 10 and/or using an outward-facing microphone 32. However, as described below with reference to FIGS. 14-20 , noise profiles 96 and/or 174 may be determined, additionally or alternatively, in response to certain other stimuli. Such stimuli may include when a user activates a non-voice-related feature, when the electronic device 10 initializes, while a user navigates to a voice-related feature, when the electronic device 10 senses a change in context, and/or while a user is using a telephone feature of the electronic device 10.
[0064] FIG. 14 is a flowchart 190 representing an embodiment of a method for determining a noise profile 96 or 174 on an irregular, non-periodical basis. Specifically, in a first step 192, the user may elect to use a non-voice-related feature of the electronic device 10. By way of example, the non-voice-related feature may be a web browser, a game, or other such feature. The act of starting or using the feature may serve as a stimulus that causes the electronic device 10 to begin determining a noise profile 96 or 174. Thus, steps 194-198 may be performed in substantially the same manner as steps 104-108 of FIG. 6 or, alternatively, steps 154-162 of FIG. 10 .
[0065] FIG. 15 is a flowchart 200 in which, as illustrated by step 202, the initialization of the electronic device 10 may serve as the stimulus to determine a noise profile 96 and/or 174. By way of example, the electronic device 10 may initialize when the electronic device 10 is turned on or awakens from a sleep mode, is unplugged from being charged, or becomes decoupled from communication with another electronic device. After the electronic device 10 has been initialized in step 202, step 204-208 may involve determining a noise profile 96 in the same manner as steps 104-108 of FIG. 6 , or steps 154-162 of FIG. 10 .
[0066] FIG. 16 is a flowchart representing an embodiment of a method in which navigating to a voice-related feature of the electronic device may serve as a stimulus to determine a noise profile 96 and/or 174. As such, in step 212, a user may initially navigate to a voice-related feature. By way of example, a user may navigate to an icon representative of the voice-related feature or may hold the button 42 with the intent to cause the voice-related feature of the electronic device 10 to activate. Step 212 may occur not after the voice-related feature has actually become activated, but rather when the user indicates an intent to activate the voice-related feature. In other words, as soon as the user navigates to a page on which the icon is listed or begins to press the button 42, steps 214-218 may begin, regardless as to the whether the user ultimately chooses to activate the voice-related feature. More generally, step 212 may encompass any action by the user that indicates intent to activate the voice-related feature. Thereafter, steps 214-218 may be performed in substantially the same manner as step 104-108 of FIG. 6 and/or steps 154-162 of FIG. 10 .
[0067] FIG. 17 is a flowchart 220 representing an embodiment of a method in which a change in context 56 may provide a stimulus for determining a noise profile 96 and/or 174. The flowchart 220 may begin when the electronic device 10 senses a change in context 56 in step 222. The change in context 56 may be determined, for example, based on a change in time, location, ambient light, amount of motion, and/or a volume of ambient sounds 60. If, as indicated respectively by decision blocks 224 and 226, a stored noise profile currently matches the new context 56 and a usage history of the voice-related feature does not suggest that the voice-related feature is likely to be used, the process may flow to step 228. In step 228, the electronic device 10 may continue operating normally without determining a noise profile 96 or a contextual noise profile 174.
[0068] However, if a stored contextual noise profile 174 does not match the current context, as noted in decision block 224, or if the voice-related feature use history indicates that the voice-related feature is likely to be used, as noted in decision block 226, a new noise profile 96 and/or 174 may be determined. As such, the process may flow to steps 230-234. Steps 230-234 may performed in substantially the same manner as steps 104-108 of FIG. 6 or steps 154-162 of FIG. 10 .
[0069] FIGS. 18-20 describe manners of determining a noise profile 96 and/or 174 while a user is using a telephone feature of the electronic device 10. Turning first to FIG. 18 , a flowchart 236 may begin with a first step 238, which occurs when a user is using a telephone feature of the electronic device 10. In step 240, a microphone 32 of electronic device 10 may sample the ambient sounds 60 that occur in between the words spoken by the user. Although the microphone 32 may record all sounds, including the user's voice, the user's voice may be louder then the ambient sounds 60 and therefore generally discernable from the ambient sounds. Furthermore, in step 242, the convergence time for determining the noise profile 96 and/or 174 may take a longer time than when the user is not currently speaking. Nevertheless, the determination of the noise profile 96 and/or 174 may be largely transparent to the user, since, unlike a voice-recognition feature, the ambient sounds 60 may not need to be removed immediately. In step 244, the determined noise profile 96 and/or 174 may be stored in memory 14 or the nonvolatile storage 16.
[0070] FIG. 19 is a flowchart 246 that similarly may begin, in step 248, when a user is using a telephone feature of the electronic device 10. Specifically, in step 250, the electronic device 10 may sample the ambient sounds 60 near the electronic device 10 at a time when the user is listening to the other person speaking over the telephone. In performing step 250, the electronic device 10 may compare when the microphone 32 produces an audio signal 94 that occurs simultaneously with a received telephone audio signal, which may correspond to a time when the other person is speaking During these times, the user generally may not be speaking and, accordingly, the microphone 32 may primarily detect only ambient sounds 60. Based on the audio signal 94 obtained in step 250, the electronic device 10 may determine a noise profile 96 and/or 174 in step 252, before storing the noise profile 96 and/or 174 in the memory 14 or the nonvolatile storage 16 in step 254.
[0071] FIG. 20 is a flowchart 256 that also may begin, in step 258, when a user is using a telephone feature of the electronic device 10. In step 260, the electronic device 10 may obtain a digital audio signal 94 from an active microphone 32, which may be the outward-facing microphone 32 of the handheld device 34 illustrated in FIG. 2 . Even while the user is speaking, the outward-facing microphone 32 may record less of the voice audio signal 58 and more of the ambient sounds 60 such that, in step 266, a noise profile 96 and/or 174 may be determined based the ambient sounds 60. In step 264, the noise profile 96 and/or 174 determined in step 262 may be stored in memory 14 or nonvolatile storage 16.
