Lecture transcription — full text instead of re-listening

Transcribing a lecture to text is useful for students and anyone studying: instead of re-listening to a 90-minute recording, you get the full text and work with it like notes — search for what you need, highlight the key points, prep for an exam. DictAI recognizes the speech from a lecture recording and returns ready text — upload audio from a recorder or a webinar video, or paste a link, and the AI turns the lecture into text automatically.

Lectures are usually long recordings, and timestamps matter here: each fragment of text is tied to a moment in the recording, so the right spot in an hour-long lecture is found in seconds, with no scrubbing by ear. If several people speak in a seminar — the lecturer and students — the AI labels lines by speaker, so questions from the room don't merge with the explanation. Recognition works in 35+ languages, including lectures in English.

Both audio and video are supported: recordings from a voice recorder or phone (MP3, M4A, WAV), video lectures and webinars (MP4), and links to recordings from 1,000+ platforms. The finished text is edited right in the browser — handy to fix terms and formatting — and exported to TXT, DOCX, or PDF. For long lectures an AI summary is available: a short digest of the key points instead of reading the whole transcript (a paid-plan feature).

Transcribing a lecture saves hours before exams: you can search the full text by keywords, quote it in your notes, and not worry about missing a detail. You can start for free — 30 minutes of transcription with no card required. Accuracy depends on recording quality: the closer the recorder is to the lecturer and the less noise in the room, the more accurate the recognition; complex terms are sometimes worth fixing in the editor.

Which lectures are convenient to transcribe

A class recorded on a recorder

Lecture audio recorded on a phone or recorder becomes text — handy to prep for an exam without re-listening to an hour and a half.

A video lecture or webinar

A recording of an online lecture or webinar becomes text with timestamps — easy to revisit the right moment and work through a hard topic.

A lecture in English

An English lecture is recognized into text in English — handy to study the material and terms by seeing the words rather than guessing by ear.
