NVSpeech Player with phoneme editor version 1.6 now on GitHub as a release.

@patricus sadly I'm stuck in work meetings, might not be able to look at it until the evening, but thank you for the huge help.

NVSpeech Player with phoneme editor version 1.6 now on GitHub as a release. https://github.com/tgeczy/NVSpeechPlayer/releases/tag/v-160
Release notes:
This release removes all direct linking against libespeak and other phonemizer libraries. Phonemization is now performed via external command-line tools (preferably through STDIN), keeping NV Speech Player and the Phoneme Editor fully GPLv2-compliant while still allowing use of GPLv3 phonemizers such as eSpeak NG as separate programs. Functionality is unchanged for users, but the integration is now cleaner, more flexible, and license-safe.

@Tamasg so i'm trying to add the french a nazelized as in the word "Dans". I don't know which phoneme this goes to, and how to add iti to the language

@spacepup For “dans”, the vowel is /ɑ̃/ (nasal A). You usually don’t add a brand-new phoneme right away. Map the nasal vowel to an oral vowel + nasal consonant:
/ɑ̃/ to ɑn (or sometimes ɑŋ, depending on taste)
That already gets you most of the way there and works well in formant synths.
In packs/lang/fr.yaml (or your French pack):
normalization:
replacements:
- from: "ɑ̃"
to: "ɑn"
That way:
• dans (/dɑ̃/) now is dan. True nasal vowels aren’t just “vowel + N”, but acoustically this approximation is very close, and much better than guessing a random vowel. Most engines (and even some older TTS systems) do exactly this.

@Tamasg but i think i understand

@spacepup You’re absolutely right — /ɑ̃/ in dans is one vowel, not “a + n”. Native speakers don’t pronounce an actual n there.
I think the reason people suggest mapping it to ɑn isn’t because that’s phonemically correct, but because of how formant synthesizers work. There is no true nasal vowel tract (no velum lowering, no nasal cavity resonator). A nasal vowel would need different formants + nasal anti-resonance, which we don’t currently model as a separate vowel type. So ɑn is a controlled approximation, not a claim about how French works. Later on we might be able to add more engine params like that though, but it requires deeper level changes to its actual sound.
