Free Hindi transcription: test tools on mixed-language speech

By the Potok teamUpdated ~2 min read

To test a free Hindi transcription tool, send a clip that mixes in English words and judge the result with a caution in mind. The announced word error rate for Hindi is 16.9, but independent tests report about 37, so Potok treats Hindi as uncertain.

Key facts

  • The 16.9 comes from the model's announcement, not from our measurement.
  • Independent tests with a different text normalisation reported about 37, and a third-party turbo average was 19.25.
  • Expect more mistakes than in the languages marked as recommended.
  • The transcript stays in Hindi and is not translated.

What a transcript looks like

Sample sentence in Hindi
[00:00] Speaker 1: चलिए बैठक शुरू करते हैं। पहले हम पिछले हफ़्ते के नतीजों की समीक्षा करेंगे, फिर अगले कदमों की योजना बनाएँगे।

Meaning in English: Let's start the meeting. First, we'll review last week's results, then plan the next steps.

The figure of 16.9 comes from the model's announcement; independent tests with a different text normalisation reported about 37, and a third-party turbo average was 19.25. Expect more mistakes than in the languages marked as recommended.

These numbers come from published tests by other people, not from tests by Potok. Your own audio, with its noise, accents and microphone, will differ.

How to do it

  1. Record mixed speech. Choose a clip where the speaker drops in English terms, as people often do.
  2. Open the bot. Open @potok_now_bot in Telegram and send the clip as a voice message or an audio file.
  3. Check which script each word has. See whether English words appear in Latin letters or in Devanagari, and whether that suits your use.
  4. Mark the spread of errors. Count the slips in the Hindi part and in the English part separately.
  5. Scale cautiously. Up to 2 GB is accepted, with Upload for large files. Export DOCX for a manual pass.

Frequently asked questions

Why does Hindi carry a caution?

Published numbers range widely, from 16.9 in the announcement to about 37 in independent tests.

Is the turbo figure relevant?

A third-party turbo average of 19.25 is one more data point, not a promise for your file.

Will English words be written in Latin letters?

It can vary from one passage to the next, so check a sample and decide whether the mix suits your use.

Which exports exist?

You can save the transcript as TXT, MD, DOCX, PDF, SRT or VTT, and DOCX is the easiest to edit by hand.

Is there an English version?

No. The transcript stays in the language of the recording.

How long should the test clip be?

A minute of natural speech is enough to see the pattern, as long as it contains both Hindi and the English words people mix in.
