# TTS Custom Pronunciation

> Override TTS pronunciation with custom lexicon dictionaries.

See the [Custom Pronunciation guide](/asr/custom-pronunciation) for the full documentation on lexicon files, word matching, and Swift API usage.

This page exists as a navigation convenience — the custom pronunciation system is shared across TTS backends (Kokoro and PocketTTS).
