@Tamasg @cachondo @jscholes @ZBennoui Yup. This all comes back to that problem of so many systems all needing tuning. I do think it would really help us to just focus on a single one. IE get this voice sounding correct with pure "aaaaaaaa" and "eeeeee" tones. No words, no pitch or intonation, nothing. Then hook that up to the rest of the systems. Then see where we land and tackle the next thing. Because thinking about the phonemizer and the IPA rules and the intonation system all at once is burning us out and distracting us from finishing the thing we have the most control over: IE the klatt synthesizer and the wave generator. Those are ours, entirely and completely. The other things are not, so those problems are harder.
