Frequently asked questions
How to improve the accuracy of your Chinese (Cantonese) transcripts?
Start by improving the quality of the Chinese (Cantonese) 3GP 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) 3GP file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Chinese (Cantonese) 3GP file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from 3GP, 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 3GP file play on my computer?
Many desktop media players lack the AMR and H.263 codecs that older 3GP files use. VLC plays most 3GP files, or you can convert the file to MP4 for wider compatibility.
Do I need to convert 3GP to MP4 before transcribing?
No, 3GP files can be uploaded directly for transcription. Converting to MP4 first is optional and mainly useful if you also want a copy in a more widely supported format.
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
Your app is amazing. Seriously, I'm blown away by the technology. The speed, accuracy, and the fact that you can play the audio and that it highlights the transcript in sync.
Gobsmackingly amazing! As a software developer of 40 years I know quality when I see it. An amazing product and a pretty damn good web-site to back it all up also. Totally staggered at the accuracy, especially when multiple voices contribute to a meeting.
