Speex dev - Aug 2004 - VAD algorithm ?

Hello,

I am working with speex codec, especially its VAD part. I need to know what
algorithm it is using for silence detection and where I can get some
documentation for it.

I will be very greatful for your help.

Note that there are two VADs in Speex. One is in vbr.c and was there in
1.0.x. The other one is new (1.1.x) and is in preprocess.c (and
separated from the codec itself). In both cases, there's no real
documentation outside of the code. Those VADs are a bunch of kludges put
together and that happen to (at least sometimes) work.
