But  Mmm. Yeah. So I did  I just  started to test  putting together two VAD which was  was not much work actually. Um , I im re - implemented a VAD that 's very close to the ,  um , energy - based VAD  that , uh , the other Aurora guys use. Um. So , which is just putting a threshold on  the noise energy ,
Mm - hmm.
and , detect detecting the first  group of four frames  that have a energy that 's above this threshold , and , uh , from this point , uh , tagging the frames there as speech. So it removes  the first silent portion  portion of each utterance. And it really removes it , um , still o on the noises where  our MLP VAD doesn't  work a lot.
Mmm.
