MP3, M4A, WAV or MP4 · Max 100 MB per file · Checking the file length limit…Return to the explanation
A lecture transcript can help you revisit an explanation and search for a term in the downloaded text. Start with an audio recording you are allowed to process, in MP3, M4A or WAV.
Lectures can exceed the free allowance or per-file duration limit. Check the limit shown in the uploader before choosing a file. The transcript covers spoken audio, not slide images, formulas written silently on a board, or automatic study summaries.
The free allowance
Guest use is included in the account total when linked. These cloud minutes do not renew monthly. There is no separate allowance for each page.
See current plans and file limits →Step by step
Use a recording you are allowed to process. Check its size against 100 MB and its duration against the uploader’s current allowance and per-file limit. Export an MP3, M4A or WAV file from your recorder or course recording app; a link or editor project is not an audio file.
Choose the saved audio file above and start transcription. Use the clearest original copy you have. If a full lecture is too long, export the section you need or review a suitable plan; smaller pieces still share the same minute balance.
Replay technical terms and figures, using the slides or reading list to check spellings and definitions. Correct the transcript, then copy it or save TXT for your own notes. Write headings, summaries and study questions yourself in your document editor.
A look at the result
An owned, 24.67-second synthetic lecture excerpt, not a real class or user feedback. This is the unedited text from a VoxText Cloud service integration test on October 6, 2026. It is not an accuracy benchmark or a browser upload/billing test. Compare it with the original script.
Before you upload
In this demo, check “independent variable,” “dependent variable” and “correlation” against the audio and script before making your own notes. The returned text joins two script sentences with a comma; punctuation still needs review. A recognizer may substitute a familiar word for a specialist term, so use your course materials to verify unfamiliar spellings.
The recording must fit the size cap, the per-file duration cap and your remaining minutes. Export the relevant section or review a paid plan on Pricing. Compressing audio reduces bytes, not lecture minutes; splitting it does not reset the guest or lifetime free balance.
Replay the original recording to see whether the question is audible. A microphone near the lecturer may not capture distant students clearly. Check the exported range and any separate channels; mark an unclear question in your notes instead of inventing its wording.
Silent board work and diagrams cannot be recovered from speech transcription. Add references to your course material manually. TXT is a text reference for later review, not an automatic summary, a set of exam answers or a replacement for the visual explanation.
Questions
No. VoxText produces an editable transcript of spoken audio. You can use that text as material for your own notes.
Only if its duration fits your remaining free allowance and per-file limit. Many lectures are longer; check the uploader and Pricing page before uploading.
Only words spoken in the recording are transcribed. Written formulas, slide text and images are not extracted.
Try up to 10 cloud minutes without signing up. A free account includes up to 30 lifetime minutes in total, including linked guest use. The allowance does not renew monthly, and no credit card is needed to try it.
Upload one MP3, M4A or WAV at a time, up to 100 MB. Your plan and remaining allowance determine the maximum duration; the uploader shows your current limit before you choose a file.
Cloud transcription sends the recording through private temporary storage and a transcription provider. VoxText requests deletion of temporary audio after processing. Completed transcripts are retrievable for up to one hour and are scheduled for deletion after delivery. See the Privacy page for details.
