The sound waves from that speaker’s voice then should reach the microphones on both sides of the headset simultaneously; there’s a 16-degree margin of error. Perhaps the accuracy of identifying the correct voice could be vastly increased by adding video input. The AI can then try to match the various voices with the lip movements in the center of the video, basically lip reading.
