Transcribe a Mandarin tuition class and revise from the page.
A Mandarin tuition class that a student records in Singapore usually runs two to three hours, and it is transcribed at about 2 minutes per hour of audio, so a 2.5-hour class takes roughly 5 minutes. The first 20 minutes are free, and a 10-week term of 2.5-hour classes is 1,500 minutes, which fits the $12 pack of 2,000.
What a tuition recording needs
The tutor's explanations, in characters you can highlight.
Ask before you record
Record a class only when the tutor agrees, and keep the transcript for your own revision. Then send the phone recording from upload page; a voice memo or video from the back of the room both work.
Exercises become chapters
Chapters mark each exercise, composition tip or comprehension passage, and the brief lists the takeaways. The idioms and vocabulary the tutor wrote on the board are in the text where they were spoken.
The term in minutes
Ten classes of 2.5 hours are 1,500 minutes on the $12 pack of 2,000, leaving 500 minutes for revision sessions. Three classes, 450 minutes, fit the $6 pack of 500.
Phone files are small
A phone voice memo at 64 kbps uses about 28.8 MB an hour (8 KB a second times 3,600 seconds), so a 3-hour class is near 86 MB. That uploads quickly, and the text is back about 6 minutes later.
Why class recordings go unplayed
A three-hour recording is too long to replay the week before an exam.
✗ Recording on the phone
Classes get recorded every week and almost never replayed, because finding one explanation takes too long. Parents pay for long classes, and students still forget half of what the tutor said by the following week. Phone recordings pile up because nobody has three hours to replay one.
- Replaying the whole class for one idiom
- Notes copied in a hurry from the board
- English-only tools for a Mandarin class
- Short upload limits
- No index of exercises
- A subscription for a school term
✓ Notes from every class
Each recording turned into Mandarin text with chapters, ready to highlight. A student reads the class in twenty minutes, highlights the vocabulary and marks the composition tips. A parent who wants to know what was covered can read the brief instead of asking.

FAQ
Mandarin tuition recordings, answered.
How long does a 2.5-hour class take to transcribe?
Roughly 5 minutes. A 3-hour class takes about 6, since the rate is about 2 minutes per hour of audio.
What will ten weeks of tuition recordings cost?
Ten 2.5-hour classes are 1,500 minutes on the $12 pack of 2,000. If you record only a few classes, three of them at 450 minutes fit the $6 pack of 500. A new visitor gets 20 minutes free, and a pack carries a longer class on from where the preview finished.
Will a three-hour phone recording upload?
A recording may run up to 10 hours or 5 GB. Before a first pack, uploads go up to 2 GB; phone voice memos of a class are usually far smaller.
Do I split a class that has a break in the middle?
No. Keep the class as one file with the break in it; only recordings over 10 hours need to be split into two.
The tutor explains some points in English. Is that handled?
Yes. Mandarin is detected automatically as the class's main language, and English explanations inside it are handled in the same transcript.
What can I download, and who else sees my class?
Your class downloads as TXT, DOCX, SRT, VTT or JSON. Tuition recordings are transcribed on our own servers and are never used for training. Many tutors are glad for students to revise this way, as long as the recording and text stay private to the student.
