is it possible to seperate different voice signals based on quality(timbre) using MATLAB

thanx in advance

U can use sppech proessing S/w , It is basially demodulation using different sampling rates.

I do not understand exactly what you want. would you please describe more. What do you want to recognize? words? consonant , vowels? continous speech? or just voice, such as the sound of a door, or sound of a breaking window? For each of the above situations, there is a solution using matlab. Example: want to detect, the breaking window sound ( A thief detector ) then matlab's wavelet toolbox can be used greatly. I addition you may want to use Matlab's neural network toolbox, to develope some simple nets for recognizing special sounds. Want to use HMM, for word recognition or Vowel consonant classification? then you can find one good library of HMM related fucntions for matlab using a simple search in google. I do not remember the name now, But I'm sure it is available. Now, please indicate your application exactly. thanks.

Be more specific describing your problem.
Voice recognition and voice separation are very different problems.
In the last case, you could use the ICA (Independent Component Analysis) approach. There is a free matlab-based toolbox called FastICA. You can find it in google. With this technique you will need as many signals as sources (at least).
Another techniques are BSS (blind source separation) and BSD (blind source deconvolution), which is necesary when the voices are recorded in a room with high reverberation.
Good luck.
