Speech Overlap Detection


    Oct 21 2013 | 9:56 am
    Hi,
    I'm trying to figure out how to go about using Max/MSP to design a procedure for differentiating between a single-voice speech and a multiple-voice conversation in which voices overlap. In other words - the moment of overlap is what I'm interested at. I want to be able to listen to a vocal conversation between two people, and detect when voices collide / overlap.
    I guess that spectral-wise there's a major difference between a speech-based conversation with no overlaps compared with a conversation with speech overlaps, so perhaps one direction to look at is detecting sudden spectral changes?
    Any thoughts / ideas / pointers for achieving this are very welcome!
    Thanks, K
