Hindi speech-to-text APIs compared: prices and features, October 2026.

Hindi speech to text is sold by the minute or by the hour. On 16 October 2026, we transcribe recorded Hindi and Hinglish calls at ₹15 an hour of audio, Sarvam lists ₹0.49 a minute, and six others price in US dollars. On Hindi phone recordings, Mira STT made fewer word errors than Sarvam's Saaras v4, 18.3% against 21.6%, and Saaras did better on clean read speech. Still, the only score that settles it is one on your own recordings.

Which one is most accurate?

Vendors measure accuracy their own way, so we don’t repeat their figures. On 20 October 2026 we sent the same public recordings to Mira STT, our own Hindi speech recognition, and to Sarvam’s Saaras v4, each through its own API, and scored both the same way.

Test Mira STT Sarvam Saaras v4
Hindi phone calls, 499 clips at 8 kHz 18.3% 21.6%
Tamil, IndicVoices 25.4% 28.5%
Clean read Hindi, Kathbath 10.1% 5.8%
Final transcript after the caller stops, p80 82 ms 290 ms

Read the limits with the numbers. Lower is better on every row, and Saaras wins on clean read speech. The other companies weren’t in this test, so it says nothing about them. Mira Transcribe, our product for recordings, adds more passes on top, so the table describes the recogniser alone. The method is on the Mira STT page.

How do I test it on my own audio?

  1. Pick twenty to fifty recordings that sound like production.
  2. Have a Hindi speaker write reference transcripts. Agree first how English words are written: “ऑर्डर” and “order” are one word to a listener and two to a WER script.
  3. Normalise spellings that sound the same, like अन्दर and अंदर. Leave grammar alone: है and हैं stay different words.
  4. Send the same files and language setting to each service, plus any vocabulary it accepts.
  5. Score word error rate, then read the worst ten yourself, watching names, numbers and amounts.
  6. Check speaker labels separately. Agent and customer swapped is still wrong.

With us, upload each file to POST /v2/transcriptions with a line of context and your vocabulary, then read the job until it completes; the transcription guide has the requests.

Questions

These are the questions developers ask us most.

Which Hindi speech-to-text API is most accurate?

It depends on the audio. On 499 public Hindi phone recordings at 8 kHz, Mira STT made 18.3% word errors, against 21.6% for Sarvam's Saaras v4 on the same clips. On clean read Hindi, Saaras does better, 5.8% against our 10.1%. Score two or three services on your own recordings.

Can you transcribe live audio?

Mira STT runs live inside every Voice Infra agent, and on its own over HTTP or a WebSocket at ₹0.30 a minute of audio. Recorded calls go through the transcription API, at ₹15 an hour of audio.

How should Hinglish be written in a transcript?

Decide before you score anything. Our transcripts write Hindi in Devanagari and English words in Latin script, the way the speakers switched, and Sarvam's codemix output mode does the same. A transcript that writes English in Devanagari can be right and still score badly against a Latin-script reference.

Is transcription priced like the agents?

No. A whole phone agent on our volume plan is ₹1.50 a minute all-in, with our line and insights. Transcribing a recording is ₹15 per hour of audio, which is ₹0.25 a minute.
