@danestange Dane was right to be suspicious. Phoneme overrides never reach the AU extension. Oh no, Dane, you caught another bug.

@danestange well, this is how you nail a bug down! That's why I love how your brain works, you give such good perceptual detail about what's sounding off and where and how it's sounding to your ears that pinning this one down was like a 30 minute thing in the end. really not bad, and now everyone who uses Classic Pitch will benefit But yeah, my Claude-code has so many markdown and memory files, 200 lines of memory, it knows about every bug, the 20 ways I tried to solve the diphthong shimmer saga, what would change for future features and how... At this point that project folder is just a markdown set for a brand new Formant Synthesis textbook, ha. So many learnings, wisdom, and experiments recorded in there it's insane. But also makes Claude code instantly know what my problems and issues are when I open it in the project.

@danestange Thanks for getting specific — that's exactly the kind of feedback that helps! You were right about the vowels. I compared our formant targets against acoustic research data (Hillenbrand et al. 1995) and found several vowels were under-fronted or had wrong diphthong sweep directions. Just pushed fixes for the TRAP, KIT, GOAT, and THOUGHT vowels. The "Scottish" quality should be noticeably reduced. The R is on the list too. Would love to hear what you think once the next build is out!

@danestange Good catches. The word-final T sharpness is from the stop frication fix we shipped a few builds back — it reduced the /tʃ/ confusion but may have left the burst a bit bright. Still tuning. The 44k aspiration thinness — you nailed it. White noise spectral density wasn't compensated at higher sample rates. Just shipped a fix for that, plus the VoiceOver settings reset. Next TestFlight build will have both
