seperation of simultaneous speech

[urbanfreak]

I have been working on seperating 2 voices recorded using a single microphone. Is it even possible? I have reached a dead end on the project.
Consider both the voices are male. Also, will it be possible if a sample is taken before hand of the two voices.

Please help!

Thanks

thanks for that article. it was helpful. but no definite solution was provided.
would like to know if anyone has ever attempted this and succeeded.

This a nice project ..We humans are able to discriminate some information and just pay attention to the one important .I think that the approach is probably with neural networks

neural networks maybe can help you recognize.
but how about seperating...
i have no idea how to go about this..

but interesting project

I've read some papers about this topic. This topic is broad : Blind Source Separation. In general, people use more than 1 channel to separate mix signals. This is the "party cocktail problem". There're several methods but I prefer ICA (Independent Component Analysis).

I have read a paper recently, about sources separation using 1 channel only. That's really interested but I haven't tested with it . You can search with the keyword "Logmax algorithm". Hope you enjoy.

thanks a lot tienpfiev. logmax algorithm was helpful.
more inputs are always welcome.

consider usig neural network at least it is the way human can seperate voices
