### Answer Based on the available documentation, the pronunciation dictionary feature is supported in Retell AI agents [(1) ]() . The API reference shows that

pronunciation_dictionary

can be configured as an array of objects with word, alphabet, and phoneme properties . However, the documentation specifically notes: "Check the dashboard to see what provider supports this feature" . This suggests that pronunciation dictionary support varies by TTS provider. The TTS provider comparison page discusses ElevenLabs, Cartesia, and MiniMax, but doesn't explicitly mention whether Retell's own voices support pronunciation dictionaries [(2) ]() . I don't have specific information in the available sources confirming whether pronunciation dictionary works with Retell's proprietary voices. I recommend checking your dashboard or reaching out to support for clarification on which TTS providers and voice models support this feature.
