Understanding Chinese (Mandarin)
GSM 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) GSM 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) GSM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Chinese (Mandarin) GSM file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from GSM, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Chinese (Mandarin) with Sonix:
Why won't my GSM file play on my computer?
GSM is a telephony codec that many consumer media players do not decode by default. Players such as VLC can open it, or you can convert the file to WAV or MP3 for broader compatibility.
Is telephone-quality GSM audio suitable for transcription?
GSM was designed specifically for human speech at an 8 kHz sample rate, so clear voice recordings generally transcribe well. As with any phone recording, heavy background noise or overlapping speakers reduces clarity.
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.
