Frequently asked questions
How to improve the accuracy of your Chinese (Cantonese) transcripts?
Start by improving the quality of the Chinese (Cantonese) AAC 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) AAC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Chinese (Cantonese) AAC file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AAC, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Chinese (Cantonese) with Sonix:
What is the difference between AAC and M4A files?
Both typically contain the same AAC-encoded audio; the difference is packaging. A .aac file is a raw ADTS stream, while a .m4a file wraps the audio in an MPEG-4 container that supports metadata such as tags, artwork, and chapters.
Why won't my AAC file open in some apps?
Raw .aac files are a bare audio stream without a standard container, so some players and editors that expect MP4/M4A files cannot read them. Renaming the extension does not fix this — remux or convert the file into an M4A or MP3 instead.
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.
