# Rime phonetic alphabet

> Reference for Rime's phonetic alphabet used to specify custom pronunciations on Mist v1 and Mist v2.

<Note>Custom pronunciation is supported on **Mist v1 and v2** only. Coda, Arcana, and Mist v3 do not yet support `phonemizeBetweenBrackets`.</Note>

Rime uses its own phonetic alphabet, inspired by the International Phonetic Alphabet (IPA), to let you specify exactly how a word should sound. You provide a phonetic string inside curly brackets and set `phonemizeBetweenBrackets: true` on the request. For the full request mechanic, see [Custom pronunciation](/docs/custom-pronunciation).

For example, the word `custom` is represented as `{k1Ast0xm}`. Even made-up words work — `gorbulets` becomes `{g1orby0ul2Ets}`.

## Stress

For **primary stress**, put `1` before the relevant vowel. For example, `comma` is `{k1am0x}`.

For **secondary stress**, put `2` in front of the relevant vowel. For example, `auctioneer` is `{2akS0In1ir}`.

All other vowels should have a `0` in front of them.
