How to transcribe a lecture recording with speaker labels
Get an accurate, speaker-labelled transcript of any lecture recording — audio or video, in dozens of languages.
A transcript is the foundation of every other study step: you cannot summarise, map or quiz a recording until it is text. The good news is that modern speech-to-text is fast and accurate enough that transcribing a full lecture takes a couple of minutes, not the length of the recording.
Here is how to get a clean, speaker-labelled transcript from any lecture — whether you recorded audio on your phone or captured a video call.
How to transcribe a recording
- 1
Upload the recording
Add an audio file (m4a, mp3) or a video file. For video, the audio is extracted in your browser first so the video stays on your device.

Let AI transcribe with diarization
The recording is transcribed with automatic language detection and speaker labels — "Speaker 1", "Speaker 2" — which is ideal for seminars and Q&A.

Read, clean or export
Read the transcript in the workspace, switch to Clean Text to remove filler, or export to DOCX/Markdown.
Why speaker labels matter for lectures
A wall of undifferentiated text is hard to study from. Speaker diarization — automatically tagging who is talking — turns a discussion into a readable script. In a seminar you can tell the professor’s answer from a student’s question; in a group project you can attribute decisions to the right person.
This matters most for exam prep: the professor’s asides ("this will be on the exam") and clarifications are often the highest-value moments, and labels make them easy to find.
Long recordings and multiple languages
Full lectures run 60–120 minutes, and Aurora handles long recordings without you splitting them manually. Automatic language detection means you do not pick a language up front, and multilingual lectures — a professor switching between languages, or quoting sources in another — are handled in a single pass.
Frequently asked questions
How long can the recording be?
Full-length lectures of one to two hours are supported. Very long recordings are processed in the background so you can keep working.
Is transcription free?
Your first document is free with no card required. After that, transcription uses credits, charged per minute and only when the transcription succeeds.
How accurate is it?
Accuracy depends mostly on audio clarity. With a reasonable recording, transcription is highly accurate and includes punctuation and paragraphing automatically.
