Abstract: A conference apparatus reduces or eliminates noise in audio for endpoints in a conference. Endpoints in the conference are designated as a primary talker and as secondary talkers. Audio for the endpoints is processed with speech detectors to characterize the audio as speech or not and to determine energy levels of the audio. As the audio is written to buffers and then read from the buffers, decisions for the gain settings of faders for read audio of the endpoints being combined in the speech selective mix. In addition, the conference apparatus can mitigate the effects of a possible speech collision that may occur during the conference between endpoints.
