Find a definition without repeatedly scrubbing through a lesson. Choose a permitted lecture recording, create a transcript, and use the edited text alongside your own notes. The tool recognizes spoken audio; equations and words shown only on slides need a separate reference.
Prepare a lesson section
For a long class, export parts under 20 minutes and 200 MB in your recording editor. Name them in order and note where each part begins in the original. A clear microphone feed is preferable to a distant recording from the back of a room. Check that the file plays before recognition.
Verify vocabulary and formulas
Choose the language actually spoken, then review names, units, symbols, and specialist vocabulary against the lesson. Slides can help you correct spelling, but the tool does not read the slides or infer a written formula. Use the transcript as study material, not an authoritative answer key.
Keep text and captions together
Download TXT for searching and annotation. If you have the matching video, export SRT/VTT and check the timing during playback. Captions retain the original spoken language; changing the recognition language will not translate a lecture. Separate parts have separate time origins.
A practical review example
Illustrative study workflow: Recording: a definition spoken at 02:15 in part 2. Transcript: check the term against the slide. Notes: keep the part name and time so you can find it again.
