Language detection
All 10 clips we sent without a language field were identified as Uzbek. Auto-detection is safe here; sending language=uz still skips the detection step.
What to do instead
We would rather you know this before you build than after. For Uzbek, look at services that train specifically on the language, such as Google Cloud Speech-to-Text or Azure AI Speech, both of which publish their language lists, or a Whisper checkpoint fine-tuned on Uzbek from Hugging Face run on your own hardware. If your audio mixes Uzbek with a well-supported language, the well-supported parts will still transcribe. You can confirm all of this on your own audio with the free credit on a new account: transcription playground.
FAQ
How accurate is Whisper for Uzbek?

Does language auto-detection work for Uzbek?
In our test, yes: all 10 clips sent without a language were identified as Uzbek. Sending language=uz still saves the detection step on every request.
Can it translate Uzbek speech to English?
The API returns Uzbek text. For English, transcribe first and translate the text with a chat model on the same key; with accuracy this low the translation will inherit the errors.
