Frequently asked questions
How to improve the accuracy of your Chinese (Cantonese) transcripts?
Start by improving the quality of the Chinese (Cantonese) 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 (Cantonese) MP4 file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Chinese (Cantonese) 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 (Cantonese) 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 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
English dictation is very accurate. And the online editor is easy to use. Also it generates SRT files that I can import in my video editors for further processing.
I've used other platforms that don't do a good job at all. Sonix was close to perfect!
