Original Abstract Submitted
techniques and apparatuses are described that perform voice activity detection using active acoustic sensing. by transmitting and receiving acoustic signals, a hearable can recognize changes in an acoustic circuit to perform voice activity detection. with active acoustic sensing, the hearable can detect a vocalization made by a user in a noisy and/or loud environment. as such, the hearable can support a voice user interface (vui) by providing an indication of when the user is speaking. the hearable can also support multi-factor voice authentication to enhance security and provide robust protection from voice attacks. in addition to being relatively unobtrusive, some hearables can be configured to support voice activity detection using active acoustic sensing without the need for additional hardware.
