Oh ! Hmm.
Mm - hmm. Yeah. So , um , there is uh ,  these parameters that I still have to  to look at. Like , I played a little bit with this overestimation factor , uh , but I still have to  to look more at this , um , at the level of noise I add after. Uh , I know that adding noise helped , um , the system just using spectral subtraction without smoothing , but I don't know right now if it 's still important or not , and if the level I choose before is still the right one. Same thing for the shape of the  the noise. Maybe it would be better to add just white noise instead of speech shaped noise.
That 'd be more like the JRASTA thing in a sense. Yeah.
Mm - hmm. Um , yep. Uh , and another thing is to  Yeah , for this I just use as noise estimate the mean , uh , spectrum of the first twenty frames of each utterance. I don't remember for this experiment what did you use for these two stage
