Create Chinese (Mandarin) closed captions

Closed captions include all audio elements (dialogue, sound effects, music cues) for deaf and hard-of-hearing viewers. Subtitles typically only include dialogue and are meant for viewers who can hear but don't understand the spoken language. Sonix can create both.

Yes. Sonix generates captions that meet ADA (Americans with Disabilities Act), Section 508, and WCAG 2.1 accessibility requirements. Our captions include accurate timing, proper synchronization, and support for required caption formats.

Yes! In the Sonix editor, you can add non-speech audio descriptions like [music playing], [applause], or [door closes]. These descriptions help deaf and hard-of-hearing viewers understand the full audio context.

Sonix delivers 85-99% accuracy for Chinese (Mandarin) captioning depending on audio quality. Clear audio with minimal background noise achieves the best results. You can review and edit captions in our browser-based editor.

All major video platforms support closed captions including YouTube, Vimeo, Facebook, Twitter, LinkedIn, and Wistia. Sonix exports SRT and VTT formats compatible with all these platforms and more.

Yes! Sonix offers a burn-in feature that permanently embeds captions into your video file. This is useful for social media where closed captions may not display automatically. See our burn-in subtitles service for more details.

Yes. Upload your Mandarin audio or video file and Sonix generates a timestamped transcript in Chinese characters, which you can edit in your browser and export to formats like DOCX, PDF, and SRT.

No — Mandarin and Cantonese are distinct spoken languages, so a Mandarin model will not accurately transcribe Cantonese speech. Confirm which language your recording uses before you upload.

Occasional English names and terms are common in Mandarin business and tech audio. Automated transcription works best when one language dominates the recording, and you can correct mixed-language segments in the transcript editor.
