Similar to this question about consonants, I'm wondering how you annotate with IPA (or any other system if IPA doesn't support it) the difference between blending vowels together (morphing between multiple vowels) and discretely shifting between them.
For example, the word "wow" is really like 3 different vowel sounds from what it seems. So I would maybe do /ʊɛʊ/. But this is blending the sounds together.
A different way to do it to demonstrate non-blending is to use glottal stops, /ʊʔɛʔʊ/, or "ʊ'ɛ'ʊ". But that is essentially putting a pause between the sounds which is the extreme.
In the middle, in between blending and putting pauses between the sounds, is just shifting from one to the next without blending. A way to replicate this is to pronounce each long, and transition to the next quickly, so "ʊʊʊʊʊʊʊɛɛɛɛɛɛɛɛɛʊʊʊʊʊʊʊʊ". If you do this quickly but not so quickly as to morph or blend them together, then it's not a glottal stop and not a blend, so it's a ________ I don't know, a discrete shift.
Wondering how to annotate this in IPA. It seems then there are 3 types:
- discretely shifting
- glottal stops
Wondering how to write all 3. If there are more ways to do it than these 3 types, that would be good to know too!
