This API endpoint allows you to determine which words are included in the Rime dictionary out of the box.We can add new words to our dictionary as needed within around 24 hours. Or you can immediately generate a custom pronunciation, which uses the Rime phonetic alphabet.If a word is not in our dictionary, our TTS model will still attempt a pronunciation, which is often suitable if the spelling follows typical linguistic patterns.In addition to the API, you can also check coverage in the Rime dashboard.
