Load your own YouTube subtitles — NoaLingua

In short

Use an SRT or WebVTT file when you have a better caption track for the same YouTube video. NoaLingua can apply its word lookup and translation to that track.

Steps

Open the matching YouTube video and choose My subtitles → Load subtitle file.
Select the SRT or WebVTT file and inspect the preview and warnings.
Choose Use on this video, then check a line near the beginning and another later on.
Use Remove file if you want to return to YouTube captions.

Try this exercise

Compare one sentence in your prepared subtitle file with the spoken sentence before starting a full lesson.

Watch out for

This workflow is for YouTube. It does not add custom-file support to Netflix; a file for another cut may not align.

Check your result

Two distant sentences appear at the right moments and their words can be selected.

A manageable session

Choose one short passage whose overall meaning you can follow. Decide what you want to practise before turning on a feature: hearing words, recalling their meaning or producing a sentence. Keep a note of the difficult moment instead of collecting every unfamiliar word. Stop when you can explain that passage without looking at its translation.

Come back to it

In your next session, try the same passage before opening the answer. If it is still difficult, shorten it and repeat the troublesome part. If it feels easy, use the expression in a new sentence or move to another passage. This is a suggested routine, not a promise of a particular learning speed.

Translation follows your chosen settings and may require an online provider. A printed exercise or exported subtitle file does not download the source video. Use material you are entitled to access and keep a backup before changing your vocabulary collection.
