So go ahead.
Um yeah , so yeah , I think if we try to develop a second stream well , there would be one stream that is the envelope and the second , it could be interesting to have that 's  something that 's more related to the fine structure of the spectrum. And. Yeah , so I don't know. We were thinking about like using ideas from  from Larry Saul , have a good voice detector , have a good , well , voiced - speech detector , that 's working on  on the FFT and  uh
Larry Saul could be an idea. We were are thinking about just  kind of uh taking the spectrum and computing the variance of  of the high resolution spectrum  and things like this.
So u s u OK. So  So many  tell you something about that. Uh we had a guy here some years ago who did some work on  um  making use of voicing information uh to  help in reducing the noise.
