I will take all that into account! The use of the glottal stop is an interesting idea (that’s what /ʔ/ is, right, as in the British pronounciation of bottle?). I’m tempted to be like “yeah just leave the rhotic out” because they’re so nuanced but maybe accepting any rhotic as being all one phoneme would work? Like having one character for the speaker’s choice of any of them? Is that a ridiculous idea or no?
I really like the idea of having just /a i u/ because they’re on the very corners of the little vowel chart and very distinct and clear.
You’re probably right about lexical tone, I think it would be doable but unnecessary. With such a distinct set of vowels though it would probably be possible to use a lot of dipthongs or possibly even tripthongs without losing the ability to distinguish the vowels?
It might also be nicer to use /ɐ/ instead of /a/.
I don’t know if other autistic people have an opinion on vibration-heavy consonants? I feel like those are really polarizing, like you love them or you hate them. It also makes a big difference to me whether they’re voiced or unvoiced – possibly voiced/unvoiced consonants could be in free variation?
I feel like it’s futile to try and figure out what sounds would be most aesthetically pleasing for ALL autistic people, but it’s interesting to consider. I was also thinking that there could be a narrower gestural/signed vocabulary for people who don’t like talking or something along those lines.
I mean I’m a total amateur with this it’s just a really really intriguing line of thought to me
