### Answer Based on the available documentation, there is no direct option to change the underlying STT (Speech-to-Text) model in Retell AI's dashboard or API. [(1) ]() [(2) ]() However, you can adjust these STT-related settings: - **`stt_mode`**: Choose between

"fast"

or

"accurate"

mode to prioritize latency or accuracy. - **`language`**: Set to

"fr-FR"

or

"fr-CA"

to optimize speech recognition for French. - **`boosted_keywords`**: Add a customized list of keywords to bias the transcriber toward specific words (names, brands, etc.) that are commonly misrecognized. For French specifically, ensure your agent's

language

is set to

"fr-FR"

(France) or

"fr-CA"

(Canadian French) . If accuracy issues persist after these adjustments, I'd recommend reaching out to Retell Support directly—they may be able to assist with backend model options not exposed in the public API.
