Abstract
The present technology can receive audio segments from sources within one or more conference room, and can create audio fingerprints from the sources. The audio fingerprints are optimized for audio in conference room environments, which include distortions from room impulse responses, and various encoding used by telecommunication networks. In some embodiments, when two audio segments are matched, a user equipment can be instructed to mute its speakers to avoid feedback. In some embodiments, when two audio segments are matched, a user equipment can be given instructions to join a conference taking place in the room in when the audio segment originated.
