For non-English use cases, Retell doesn’t currently support pronunciation dictionaries outside English + Eleven labs. The usual workaround is to control pronunciation at the text level, either by adjusting spellings to guide the TTS, using phoneme/SSML support if your TTS allows it, or preprocessing the text before it’s sent to the agent. If you tell me the language and TTS you’re using, I can suggest the most reliable approach.
