Understanding Chinese (Mandarin)
MP4 files
Standard Mandarin (Putonghua in mainland China, Guoyu in Taiwan) is based on Beijing pronunciation, but regional accents differ noticeably — Taiwanese and southern speakers often merge the retroflex zh/ch/sh sounds with z/c/s, while northern speech adds erhua (r-coloring). Mandarin is also distinct from Cantonese, Shanghainese, and Hokkien, which are separate Chinese languages and not mutually intelligible with it.

Frequently asked questions
How to improve the accuracy of your Chinese (Mandarin) transcripts?
Start by improving the quality of the Chinese (Mandarin) MP4 file that you upload to Sonix. Please use high quality recording equipment, recording in a quiet environment, and ensure that your speakers are speaking clearly to ensure that your transcript is as accurate as possible.
Any advice for the Chinese (Mandarin) MP4 file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Chinese (Mandarin) MP4 file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MP4, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Chinese (Mandarin) with Sonix:
Do I need to extract the audio from an MP4 before transcribing it?
No. Because MP4 is a container that holds both video and audio streams, the audio track can be read directly from the file, so you can upload the video as is.
Why does my MP4 file play video but no sound?
The file may contain a video stream with no audio track, or its audio may use a codec your player does not support. Checking the file's stream details in a tool like VLC or re-exporting it with an AAC audio track usually resolves the issue.
Can Sonix transcribe Mandarin Chinese audio and video?
Yes. Upload your Mandarin audio or video file and Sonix generates a timestamped transcript in Chinese characters, which you can edit in your browser and export to formats like DOCX, PDF, and SRT.
Does Mandarin transcription work for Cantonese recordings?
No — Mandarin and Cantonese are distinct spoken languages, so a Mandarin model will not accurately transcribe Cantonese speech. Confirm which language your recording uses before you upload.
Can Sonix handle Mandarin recordings that mix in English words?
Occasional English names and terms are common in Mandarin business and tech audio. Automated transcription works best when one language dominates the recording, and you can correct mixed-language segments in the transcript editor.
