About this tool
Everything you need to know about Lecture Transcription
A recorded lecture or seminar can run long, and that's exactly what Pro's 3-hour-per-file ceiling is built to cover — upload the recording and get back a plain text transcript plus its duration, ready to turn into study notes or a searchable reading. A standard hour-long class fits Lite's 1-hour limit, and a quick recap or short seminar clip fits inside the free tier's 20 minutes. There's no speaker separation, so a lecture with audience questions comes back as one continuous transcript rather than split between instructor and students. Long recordings process as a background job, so a three-hour seminar takes a few minutes to come back, not a live wait.

FAQ
Lecture Transcription — FAQ
Common questions users ask about the Lecture Transcription voice. If you need additional help, please contact us via the contact form or email us at support@vocallab.ai.
Can it handle a full three-hour lecture in one file?
Yes, on Pro the per-file ceiling is 3 hours, and Max raises that to 6 hours if a session runs even longer.
Does it separate the professor's voice from student questions?
No, there are no speaker labels, so a lecture with audience questions returns as one continuous block of text.
How long does a long recording take to process?
Long files run as a background job — a multi-hour lecture typically takes a few minutes to finish, so you submit it and check back.
Can I get captions to go with a recorded lecture video?
No, the output here is a plain text transcript and duration; if you have a video file, extract its audio first and know that no captions or timing data come back.
