Mandarin, tones and characters
Mandarin is a tonal language — the same syllable can mean different things depending on its tone — and it has many homophones, so context matters. ConvertSpeech is tuned for standard Mandarin (Putonghua) and produces simplified-character text from clear recordings.
This page is set up for Mainland Mandarin. Speakers with strong regional accents, or audio that mixes in other Chinese languages such as Cantonese, are harder for any automatic system. The clearest results come from standard Mandarin spoken clearly, with little background noise.
Tips for accurate Mandarin transcription
- Record with a good microphone and minimal background noise — clean audio is the biggest factor with a tonal language.
- Keep the language set to Chinese (Mandarin) rather than auto-detect when you know the recording is Mandarin.
- One speaker at a time transcribes best; overlapping speech reduces accuracy.
- For interviews, enable speaker detection (a free registered feature) to label each speaker.
