3. Wait for the lines to appear, then read them through.
4. Copy the text or download it as TXT, SRT or VTT.

How well it understands Bengali

The Whisper model was trained on far more English than Bengali, so expect more mistakes than with English: unusual names, place names and fast speech are the usual trouble spots. Clear speech recorded close to the microphone gives the best results, and Accurate mode is noticeably better than Quick for Bengali.

Bengali mixed with English is common in everyday conversation. The model may write the English words in Bengali script or switch scripts mid-sentence. If you need a clean document, the English translation is often easier to edit.

What people use it for

Bengali lectures, adda recordings and voice notes, spoken in West Bengal, Tripura and Bangladesh and by Bengali speakers everywhere. The subtitle formats also let you add Bengali or English captions to videos.

Frequently asked questions

Is my recording uploaded to a server?

No. The speech model is downloaded to your browser once and the audio is transcribed on your own phone or computer. The file never leaves your device.

Why is the first transcription slower?

The first time, your browser downloads the speech model (about 40 MB for Quick, 80 MB for Balanced, 250 MB for Accurate). After that it is cached and starts in seconds, even offline.

How long can the recording be?

There is no fixed limit. An hour-long lecture works on most laptops; on a phone, recordings under about 30 minutes are more comfortable. Lines appear while it works, so you can stop at any point and keep what is done.

Which script does the Bengali transcript use?

Bengali (Bangla) script, the standard way Bengali is written. Tick Translate to English if you want the text in English instead.

Can I get Bengali in Roman (English) letters?

Not directly. The model writes Bengali in Bengali script or translates it to English; it does not transliterate.
