Uh - huh. Yeah.
Um , so , uh , what we basically did so far was using the mixed file to  to detect s speech or nonspeech  portions in that.
Mm - hmm.
And what I did so far is I just used our old Munich system , which is an HMM - ba based system with Gaussian mixtures for s speech and nonspeech. And it was a system which used only one Gaussian for silence and one Gaussian for speech. And now I added , uh , multi - mixture possibility for   for speech and nonspeech.
