I'm tring to use the VAD (via preprocess.c) to compare two audio file when one is a recording of the other. I assumed that I will get an identical "array" of speech/no speech frames, but i didn't. Is it possible to it ? Did I have to make any changes in code /options ? Thanks Rami _________________________________________________________________ Express yourself instantly with MSN Messenger!
