Phonemes - Akapulu Labs

Phonemes are how a line is pronounced — a string of sound symbols, not English spelling. Misaki is the grapheme-to-phoneme (G2P) engine we use. If you send English text, Misaki converts it to this American English alphabet. Pass phonemes yourself when you want tighter control over a word (a name, a stress, a vowel).

Right now you can only edit phonemes for an American accent. Other accents and languages are coming soon.

How to send text vs phonemes on a take is in Workflow. Most symbols below follow Misaki’s EN_PHONES.md. One extra: unstressed a / an / am use ɐ, which that table omits but Misaki still emits. This is not textbook IPA. Capital A, I, W, Y, and O are diphthongs.
