Patent attributes
Various implementations include wearable audio devices configured to record a user's voice without recording other ambient acoustic signals, such as others talking nearby. In some particular aspects, a wearable audio device includes: a frame for contacting a head of a user; an electro-acoustic transducer within the frame and configured to output audio signals; at least one microphone; a voice activity detection (VAD) accelerometer; and a controller coupled with the electro-acoustic transducer, the at least one microphone and the VAD accelerometer, the controller configured in a first mode to: detect that the user is speaking; and record a voice of the user solely with signals from the VAD accelerometer in response to detecting that the user is speaking.
