Abstract
Disclosed are systems and techniques for detecting audio sources and configuring acoustic device settings. For instance, a wireless device can obtain a first set of radio frequency (RF) sensing data associated with a first plurality of received waveforms corresponding to a first transmitted waveform reflected off of a plurality of reflectors. Based on the first set of RF sensing data, the wireless device can determine a classification of a first reflector from the plurality of reflectors. The wireless device can determine at least one acoustic setting based on the classification of the at least one reflector.
Claims31
A wireless device, comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and configured to:
- obtain a first set of radio frequency (RF) sensing data associated with a first plurality of received waveforms corresponding to a first transmitted waveform reflected off of a plurality of reflectors;
- determine a classification of a first reflector from the plurality of reflectors based on the first set of RF sensing data;
- enable an audio detection device from an idle mode in response to determining that the classification of the first reflector corresponds to an object that is capable of producing sound, wherein the audio detection device is configured to receive speech input;
- and
- provide an indication that the audio detection device is ready to receive speech input based on the object that is capable of producing sound being detected.
