Abstract
The disclosed techniques provide enhanced techniques for reducing audio feedback during communication sessions. A system utilizes beacon signals to determine if two or more client devices are co-located. The system uses two different beacon signals communicated from two different devices if one of the devices joins a meeting with an active microphone. However, the system only utilizes one beacon signal from the joining device if the joining device has a muted microphone and speaker. Once two or more client devices are determined to be co-located, the system invokes a co-location mode that activates the microphones of each co-located client devices to allow each device to contribute audio content to a meeting for use in transcripts, recordings, meeting summaries, and verbal commands, while also preventing the co-located devices from sharing audio signals between one another.
