And , um , Let 's  l let 's see. Um , OK. And then there 's um , another thing I wanna start looking at , um ,  wi is , um , the choice of the analysis window length. So I 've just been using two seconds just because that 's what Carlos did before. Uh , I wrote to him asking about he chose the two seconds. And it seemed like he chose it a bit informally. So , um , with the  with the HTK set - up I should be able to do some experiments , on just varying that length , say between one and three seconds , in a few different reverberation conditions , um , say this room and also a few of the artificial impulse responses we have for reverberation , just , um , making some plots and seeing how they look. And , um , so , with the  the sampling rate I was using , one second or two seconds or four seconds is at a power of two um , number of samples and , um , I 'll  I 'll jus f for the ones in between I guess I 'll just zero - pad.
Mm - hmm. I guess one thing that might also be an issue , uh , cuz part of what you 're doing is you 're getting a  a spectrum over a bunch of different kinds of speech sounds. Um , and so it might matter how fast someone was talking for instance.
Oh.
You know , if you  if  if  if there 's a lot of phones in one second maybe you 'll get a  a really good sampling of all these different things , and   and , uh , on the other hand if someone 's talking slowly maybe you 'd need more. So
