[Olympus developers 233]: Problems with VAD

[José David Lopes]

I'm working on a dialogue system with a different ASR module. I'm
experiencing some problems with the VAD. This module seems very
sensitive, triggering very easily, and thus forwarding the data coming
from the microphone to the engines even if it is not speech. I was
wondering if I could convert our own GMM models for VAD to the sphinx 3
format. Is there any tool available to convert a standard format (for
instance HTK) to sphinx 3 format? I could also train GMMs using our own
Olympus data. Did anyone did this before?

Best,
Jose David
