A: Hi Ludovic,
Sorry for the delay in getting back to you!

The list of supported languages comes directly from the models we use for transcription — OpenAI Whisper and 11Labs. You can check the full lists here:
OpenAI Whisper https://github.com/openai/whisper#available-models-and-languages
11Labs https://elevenlabs.io/docs/capabilities/speech-to-text#breakdown-of-language-support

Khmer is included!
Thanks a lot!
