Transcribe a Samsung Voice Recorder file the full lecture, from the phone.
Samsung Voice Recorder on a Galaxy phone saves recordings as M4A files, and a two-hour lecture recorded that way is transcribed here in about 4 minutes. Upload it from the phone's browser or a computer, read the first 20 minutes free, and finish it on a $6 pack of 500 minutes.
From a Galaxy phone
The lecture you recorded on your phone, as notes you can search.
Where the recording sits
Each recording is listed inside the Voice Recorder app, and the file itself is kept on the phone's internal storage, usually in a Recordings folder you can open in My Files. From the browser's upload box, choose the file from that folder.
Through a computer instead
Connect the phone by USB and copy the M4A across, or share it from the app to Google Drive. A Drive share link set so anyone with the link can view can be pasted straight into the box, so nothing has to be downloaded again.
Four minutes for a lecture
A two-hour lecture is ready in about 4 minutes at 2 minutes per audio hour. A three-hour review session takes about 6. The phone does not have to stay on the page once the upload has finished.
Notes worth revising from
The text arrives with a brief of the main points, chapters with timestamps, the names, numbers and dates the speaker mentioned, and the questions the lecture answers. The chat over the transcript lets you ask where a definition was given.
What usually happens to these files
Recorded every week, opened almost never.
✗ A folder of untouched lectures
Phones make recording easy and leave the listening to you.

- Around 2 minutes for each lecture hour
- Instructor and students named in the summary and chapters
- Chapters to revise topic by topic
- 500 minutes for $6, kept until used

FAQ
Samsung Voice Recorder files, answered.
How long does a Voice Recorder file take?
Expect roughly 2 minutes of processing for every recorded hour. Most single lectures are back within 2 to 6 minutes, and the finished text stays in your Library.
How much would a whole course of recorded lectures cost?
A typical course of thirteen weekly two-hour lectures is 1,560 minutes, which fits the $12 pack of 2,000 minutes with 440 to spare. One two-hour lecture, 120 minutes, fits the $6 pack of 500 minutes, after the first 20 minutes free.
Is my recording too large?
Almost certainly not. An M4A of speech is small, and one file may be up to 10 hours or 5 GB. Files up to 2 GB upload before any pack is bought.
Does a long Voice Recorder file have to be cut up?
Only if it runs past 10 hours. Otherwise upload it whole so the chapters and timestamps line up with the original.
Will it understand a lecture that is not in English?
Yes. 99 languages are detected automatically, including Tagalog, Korean and Spanish. For Cebuano or another regional Philippine language, the result is a fast first draft; plan one review pass.
Which formats can I download, and who can hear the recording?
One run gives you Text, Word, caption and JSON files. Recordings are transcribed on our own servers and are never used for training.
