Voice activity detection
...(preprocess_state, shortPointer);
but how do I know if the frame contained voice? I tried
if (preprocess_state->was_voice == 1)
{
...Do voice present code...
}
But the compiler complains that was_voice is not defined, which, I
assume, comes from the fact that preprocess_state is declared in
speech_preprocess.h as struct SpeexPreprocessState_;
How do I check the preprocessor for the presence of voice in a frame?
Thanks,
Evgueni

Problem related to Voice activity detection
hi guys,
i am trying to develop an application having a capability to detect voice activity in voice stream and then record only portion of this stream which contains the activity. i went through these steps.
1. Captured voice through Waveform Functions of Windows Multimedia API
2. Started Speex Preprocessing liberary
3. Turned on preprocessor by calling speex_preprocess_state_init and
