## Problem

The Lepton whisperx API translates my audio to another language automatically. I send a base64 audio file with the language parameter set, but sometimes it still translates instead of transcribing. How do I make it just transcribe?

## Verified fix

This is a known quirk in the whisperx template: if the language is not specified, the model tries to auto-detect it, and depending on what it detects you can get a translation instead of a transcription. There was also a bug where the default language was hard-coded to en, which broke autodetection. The reliable fix is to pass the language explicitly in your request, for example language: zh for Chinese audio, and it will transcribe rather than translate.
