Speex dev - Aug 2009 - VAD performance worse on version 1.2rc1 than 1.1.12

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 
detection.

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

Regards.

Thank you, but I am thinking about trying to move VAD implementation from
1.1.12 to 1.2.

I'm not sure about how difficult it could be (maybe impossible due to Jean
Marc has disappear).

Have you tried this?

Cecile.
