Yeah.
Do y wanna say anything about  You  you actually been  Uh , last week you were doing this stuff with Pierre , you were  you were mentioning. Is that  that something worth talking about , or  ?
Um , it 's  Well , um , it  I don't think it directly relates. Um , well , so , I was helping a speech researcher named Pierre Divenyi and he 's int He wanted to um , look at um , how people respond to formant changes , I think. Um. So he  he created a lot of synthetic audio files of vowel - to - vowel transitions , and then he wanted a psycho - acoustic um , spectrum. And he wanted to look at um , how the energy is moving  over time in that spectrum and compare that to the  to the listener tests. And , um. So , I gave him a PLP spectrum. And  to um  he  he t wanted to track the peaks so he could look at how they 're moving. So I took the um , PLP LPC coefficients and um , I found the roots. This was something that Stephane suggested. I found the roots of the um , LPC polynomial to , um , track the peaks in the , um , PLP LPC spectra.
well there is aligned spectral pairs , is like the  the  Is that the aligned s
