Hi Parisa, I am not sure if this gives a complete answer to your query, but I would like to put forward some of my views. I feel cepstrum coeffcients are best features for discriminating speakers. A techniques to reduce the feed for an NN is vector Quantise the cepstrum features and combining them with Formant frequencies. Hope this helps.. Best, Nagesh.
