Cantonese is the prestige variety of the Yue Chinese group, and the Guangzhou–Hong Kong standard dominates broadcasting and film. Related Yue varieties such as Taishanese differ substantially from standard Cantonese, and Hong Kong speakers frequently mix English words into everyday speech.

Frequently asked questions
How to improve the accuracy of your Chinese (Cantonese) transcripts?
Start by improving the quality of the Chinese (Cantonese) CAF 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 (Cantonese) CAF file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Chinese (Cantonese) CAF file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from CAF, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Chinese (Cantonese) with Sonix:
Why won't my CAF file play on Windows?
CAF is an Apple container that most Windows applications do not support natively. You can open it with a third-party player such as VLC, or convert it to WAV or MP3 for broader compatibility.
How large can a CAF file be?
CAF uses 64-bit file offsets, so there is no practical size limit and recordings can run for many hours. This is the main advantage over WAV and AIFF, which are capped at 4 GB.
Can Sonix transcribe Cantonese audio and video?
Yes. Upload your file, select Cantonese as the language, and Sonix generates a transcript you can edit in the browser and export to formats like Word, text, and subtitle files.
Does Sonix treat Cantonese and Mandarin as different languages?
Yes, they are separate language selections. Spoken Cantonese and Mandarin are not mutually intelligible, so choose Cantonese for Cantonese-language recordings.
Can I create Cantonese subtitles from my transcript?
Yes. After transcribing and editing, you can export subtitle formats such as SRT and VTT for use in video players and editing software.
