Abstract

A computer implemented method includes receiving multiple channels of audio from three or more microphones detecting speech from a meeting of multiple users, localizing speech sources to determine an approximate direction of arrival of speech from a user, using a speech unmixing model to select two channels corresponding to a primary and a secondary microphone, and sending the two selected channels to a meeting server for generation of a speaker attributed meeting transcript.
