Abstract: An audio speaker system for a home theater including a number of microphones, a number of speakers, each speaker located at a different location in a room, and a processor electrically connected to the plurality of microphones and wirelessly connected to the plurality of speakers. The processor is configured to generate an audio signal to send to each speaker of the plurality of speakers, output audio from each speaker of the plurality of speakers based on the audio signal, receive the audio at each microphone from each speaker of the plurality of speakers, determine a location of each speaker relative to the plurality of microphones based on the received audio at each microphone, and assign an audio channel to each speaker based on the determined location.

Abstract: Many headsets include automatic noise cancellation (ANC) which dramatically reduces perceived background noise and improves user listening experience. Unfortunately, the voice microphones in these devices often capture ambient noise that the headsets output during phone calls or other communication sessions to other users. In response, many headsets and communication devices provide manual muting circuitry, but users frequently forget to turn the muting on and/or off creating further problems as they communicate. To address this, the present inventors devised, among other things, an exemplary headset that detects the absence or presence of user speech, automatically muting and unmuting the voice microphone without user intervention. Some embodiments leverage relationships between feedback and feedforward signals in ANC circuitry to detect user speech, avoiding the addition of extra hardware to the headset. Other embodiments also leverage the speech detection function to activate and deactivate keyword detectors, and/or sidetone circuits, thus extending battery.
