WEARABLE AUDIO DEVICE HAVING WHISPER VOICE INPUT
Aspects of the present disclosure provide techniques, including devices and systems implementing the techniques, to discreetly enable a user to perform a desired command or action on the wearable audio output device. In certain aspects, enabling the commands or actions to be performed may involve at least one audio sensor detecting a command from a user, where the command is a whisper or spoken at a volume level of about 50 dB or less, to discreetly enable a desired audio mode. In certain aspects, enabling the commands or actions to be performed may involve at least one ultrasound sensor detecting information capturing movement from at least one of a small joint or ear from a user, where the movement detected correlates to a user whispering.
1 . A wearable audio device, comprising:
a housing;
at least one audio sensor disposed in or on the housing; and
at least one processor configured to:
receive input from the at least one audio sensor;
detect, using the at least one audio sensor, audio from a user of the wearable audio device; and
perform an action in response to determining that i) a volume level of the audio from the user of the wearable audio device is below a threshold and ii) the audio indicates a desired performance of the action.
2 . The wearable audio device of claim 1 , wherein the volume level is below a normal speaking volume level of the user.
3 . The wearable audio device of claim 1 , wherein the threshold is at most 50 dB.
4 . The wearable audio device of claim 1 , wherein one or more audio sensors of the at least one audio sensor is a microphone.
5 . The wearable audio device of claim 4 , wherein the microphone is a feedback microphone disposed within the housing.
6 . The wearable audio device of claim 1 , wherein the housing is acoustically coupled with an ear canal of the user to define an acoustic volume, and wherein one or more audio sensors of the at least one audio sensor is included in the acoustic volume.
7 . The wearable audio device of claim 1 , wherein the at least one processor is further configured to extract the user’s audio from other audio sensed.
8 . The wearable audio device of claim 1 , wherein the determination triggers the performance of the action.
9 . The wearable audio device of claim 1 , wherein the audio from the user is a whisper.
10 . The wearable audio device of claim 1 , wherein determining that the volume level of the audio from the user of the wearable audio device is below the threshold comprises determining that the characteristics of the audio is whisper speech.
11 . A method of using a wearable audio device, comprising:
receiving input from at least one audio sensor of a wearable audio device;
detecting, using the at least one audio sensor, audio from a user of the wearable audio device; and
performing an action in response to determining that i) a volume level of the audio from the user of the wearable audio device is below a threshold and ii) the audio indicates a desired performance of the action.
12 . The method of claim 11 , wherein the audio from the user is a whisper.
13 . The method of claim 11 , wherein the threshold is at most 50 dB.
14 . The method of claim 11 , wherein one or more audio sensors of the at least one audio sensor is a microphone.
15 . The method of claim 14 , wherein the microphone is a feedback microphone disposed within a housing.
16 . The method of claim 11 , further comprising: defining an acoustic volume using a housing of the wearable audio device, the housing being acoustically coupled with an ear canal of the user, and wherein one or more audio sensors of the at least one audio sensor is included in the acoustic volume.
17 . The method of claim 11 , further comprising extracting the user’s audio from other audio sensed.
18 . The method of claim 11 , wherein the determination triggers the performance of the action.
19 . The method of claim 11 , wherein determining that the volume level of the audio from the user of the wearable audio device is below the threshold comprises determining that the characteristics of the audio is whisper speech.
