Re: Separation of speech from multiple speakers speaking in different microphones connected to a mixer

Hi ,

Suppose there are two speakers speaking in two different
microphones connected to a
mixer.Are there any known algorithms which can separate the
speech of the two people
from output signal of the mixer.

Consider one person is male and other female. Will this make
things simpler.

How about separating the voiced segments alone.(say one is
utteing the vowel 'aaa' and
the other 'eee')

Can Linear prediction analysis still be used to seperate the
vocal tract filter and
the source. If so what is the order of the LPC to be used
assuming 8khz sampling rate.

What will be the chracteristics of the source function of such a
composite speech.

Given such a signal is there any algorithm which can identify
that there are two different
speakers.

Given the data of the two speakers(when they are speaking alone)
will this be of
any use.

Is there any algorithm which can track the speech of one person
alone given the data
of that person(when speaking alone).

Consider one person singing (opera) on one microphonel and the
other person reading
news on another microphone . Is there any known algorithm to
identify such a case.

Is this spam? Anyhoo, use google, search for, oh I don't know - how about
"audio separation."
