Add Custom Pronunciation

Customize how your UponAI agent pronounces specific words using IPA or CMU phonetic dictionaries.

This feature only works with English agents using ElevenLabs voices that have selected the eleven turbo v2 (English only) voice model.

You can control how certain words are pronounced. This is useful for uncommon terms, brand names, or technical words that the TTS model mispronounces by default.

How It Works

Set a pronunciation dictionary for the agent. Each entry has three fields:

Field	Description	Example
Word	The word to be pronounced	actually
Phonetic alphabet	ipa or cmu	ipa
Pronunciation	The phonetic spelling of the word	æktʃuəli
