Hello, What should the following input produce? Dutch has shifted Germanic g to the velar fricatives [?] and [x], but retained the spelling with <g> and thus at least a visual similarity to German; English and Frisian have shifted g to [j] before palatal vowels The Dingus says: <p>Dutch has shifted Germanic g to the velar fricatives [?] and [x], but retained the spelling...

...red to us that there seems to have been a regression in the quality of encoding since version beta1. We are compressing some 22khz wave files in wb mode with maximum quality / complexity in VBR, and the result was really great with speex beta1. With rc1 (or beta3), there is a clear degradation for fricatives, which gives a very audible (and annoying) feeling of a muffled voice. This problem does not seem to affect CBR encoding, only VBR. It does not appear to affect 16k files as much either. Hope that will help you improve speex again! Blaise P.S.: Is there any plan to make uwb mode really usabl...

...n the compression ratio is particularly high: what phonemes become more difficult to distinguish soonest, as the compression ratio goes up? And then, if possible, I'd like to come up with an analysis of *why* those particular sounds are poorly recreated, as opposed to others. My guess is that fricative sounds (/f/, /v/, /s/, /z/) will "degrade" first because they contain larger amounts of white noise, which is often poorly handled by compression. A couple other people in my classes are interested in working with me on the project - one has more math background, one is willing to adm...

hi, thanks for answers to my previous qns. have some more of them. hope it's ok to ask questions on the basics of CELP here. let me know if it's not. 1) synthesized filter stability after interpolation of LSFs I read from some resources that if LSF representation of LPCs is used for interpolation, stability of the synthesis filter is guaranteed. from another source, i read that the
