Hi, I have a small question regarding SPEEX_PREPROCESS_SET_PROB_START and SPEEX_PREPROCESS_SET_PROB_CONTINUE. Is PROB_START the probability that the VAD says "voice is active" or is it the probability that VAD says "voice is NOT active"? Same question for PROB_CONTINUE. Because of the name PROB_START I thought it's the probability that voice is recognised as acitve. But I played around with the values and it seems to be the probability that voice is NOT active: PROB_START = 10; Stream is always sent. PROB_START = 90; Stream is only sent if I'm talking. (Same for PROB_CONTINUE) Please clarify this! Thanks for your help!
