@rommix0 ah, now that filename suddenly makes sense from earlier, nice handle change

@raph My trapezoidal SVF has the same issue since it's mathematically equivalent. At 11025 Hz the upper formants (F5/F6) are getting squeezed noticeably near Nyquist. Pre-warping fixes center frequency but not bandwidth shape.The voiced lowpass idea has merit. I have spectral tilt on the source already but a proper LP at 4-5 kHz before the resonator bank could help. Oversampling just the voiced path is tempting too, since noise sources don't alias the same way.

@Tamasg Spoken like a true AI robot!

@DavidGoldfield lol no way really? I didn't think people are actually using that thing.

@rommix0In our synthesizer, each phoneme token has ONE set of formant values. The DSP interpolates between tokens via a fade parameter.When we tried inserting a short 'onset' segment at locus values before vowels, it created artifacts - either 'gritted' sound (segment too long) or 'shaky' wobble (multiple segments accumulating). How does DECTalk/Klatt handle this? Does each segment have separate START and END formant values that the synth interpolates between? Or is there some other mechanism for smooth within-vowel transitions?
