Hi Cecile,

it seems it is a tabu theme, or nobody uses VAD on speex. I've tried 
with external EasyVAD solution but the result was not as spected.
Other users of the list suggest an algorithm to filter voice based on 
the power of the signal, but of course, it is not a voice activity 

I am waiting also a solution for this, while so I use version 1.1.12.
