Frequently asked questions
How to improve the accuracy of your Chinese (Cantonese) transcripts?
Start by improving the quality of the Chinese (Cantonese) OPUS 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) OPUS file that I upload?

Aside from OPUS, 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 OPUS file play on my computer?
Older media players and some built-in OS players lack Opus support. Opening the file in VLC or a modern web browser, or converting it to MP3 or WAV, usually resolves the issue.
Are WhatsApp voice messages OPUS files?
Yes, WhatsApp exports voice notes as .opus files. You can upload them for transcription directly without converting them first.
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.
Trusted by professionals worldwide
I have absolute admiration for the impressive transcription done to 3 short YouTube videos. It is truly amazing how accurately it recorded the correct words and so well paragraphed as well.
Seriously the best transcript I’ve ever seen. And the synchronized editor is amazing. I will be using again and I will be sharing with my friends :)
