Hi All I have to detect voice activity in a stream. Is that possible at the moment with Speex VAD ? I've tried VAD detection but it doesn't seem to work for me, besides I get a warning message when I use it. I'm not sure where is the problem, but I tried the "testdenoise.c" code as well and uncommented the VAD printout line [ fprintf (stderr, "%d\n", vad); ] and it doesn't work for me either. Any thoughts ? All I need to do is detect voice activity... Thanks Alvaro.
