<@1145576664366055464> what transcriber does retell use

Thanks for tagging me <@225304633822806016>. I'll look through relevant sources and get back to you shortly.

### Answer
 

Retell AI does not publicly disclose the exact STT (speech-to-text) provider they use. [(1) ](<https://discord.com/channels/1186424376300679209/1349306527042764863>)

However, you can configure transcription settings at the agent level:

- **`stt_mode`**: Choose between `fast`, `accurate`, or `custom` modes [(2) ](<https://docs.retellai.com/api-references/create-agent>)
- **`custom_stt_config`**: When using custom mode, you can specify a provider (e.g., `azure`) and configure settings like `endpointing_ms` 
- **`language`**: Set the speech recognition language/dialect (e.g., `en-US`, `en-GB`, `multi` for multilingual support) 

The system uses Automatic Speech Recognition (ASR) to transcribe live caller speech into text during the conversation. [(3) ](<https://www.retellai.com/glossary/call-transcription>)
