Poor. Good for topic and keywords. Not good enough to read as a transcript. The clips are clean, single-speaker read speech, so treat this as a best case for your own recordings. How we measured, and all 83 languages.

Language detection
All 10 clips we sent without a language field were identified as Hindi. Auto-detection is safe here; sending language=hi still skips the detection step.
What to do instead
We would rather you know this before you build than after. For Hindi, 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 Hindi from Hugging Face run on your own hardware. If your audio mixes Hindi 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.
Text-to-speech in Hindi
The reverse direction is covered too: hear the Hindi voices on the Hindi text-to-speech page.
FAQ
How accurate is Whisper for Hindi?
On 30 clean read-speech clips it made 43% word errors, about one word in 2. Good for topic and keywords. Not good enough to read as a transcript. Real recordings with noise, accents or several speakers will score worse.
Does language auto-detection work for Hindi?
In our test, yes: all 10 clips sent without a language were identified as Hindi. Sending language=hi still saves the detection step on every request.
Can it translate Hindi speech to English?
The API returns Hindi 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.
