...re is not noise outside speech. I don't feel problem so much while continuous speech, but when we speak for short intervals, the start of and end of sentences have clatter (maybe clatter does not meet that sound, there is a defect).

...re is not noise outside speech. I don't feel problem so much while continuous speech, but when we speak for short intervals, the start of and end of sentences have clatter (maybe clatter does not meet that sound, there is a defect). To overcome this problem, are SPEEX_PREPROCESS_SET_PROB_START, SPEEX_PREPROCESS_SET_PROB_CONTINUE parameters or if (st->nb_preprocess%200==0) in preprocessor.c (line 608) useful?

Sorry. I forgotten the words volume or loudness. But it is know as microphone stroke too, i think. If something can tell me something about that procedure it would complete my pleasure. To bring back memories, i only wanted to know wheather i can change a variable that holds the sound intensity (loudness) needet to start "encoding >> sending" if the speex codec is in voice
