Lecture recording to text

Choose a recorded class or online lecture and get a timestamped transcript you can turn into notes.

How to turn a lecture recording into text

1. Choose the recording (audio or video).
2. Pick the language the teacher speaks; use Accurate for Hindi and other Indian languages.
3. Keep Timestamps on so you can jump back to the recording.
4. Download the text and turn it into short notes.

From transcript to revision notes

A raw transcript is long. Skim it once, mark the definitions, formulas and examples, and copy those into your notes with their timestamps. When a point is unclear, the timestamp tells you exactly where to replay the recording.

Ask your teacher before recording a class, and keep recordings for your own study.

Recording tips

Sit near the front or place your phone near the teacher. A cheap clip-on microphone makes a big difference in large halls. Recordings of online classes are usually clear enough to transcribe as they are.

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.

Can it handle a two-hour lecture?

On a laptop, yes; it takes a while, and lines appear as it goes. On a phone, split long recordings or use Quick mode.
