Everything you need to know about
accessibility transcription
Why is transcription important for accessibility?
Transcription makes audio and video content accessible to people who are deaf or hard of hearing. It also benefits non-native speakers, people in sound-sensitive environments, and those who prefer reading to listening. Approximately 15% of the world's population has some form of hearing loss.
Does Sonix help with ADA compliance?
Yes. Sonix helps organizations meet ADA requirements by providing accurate transcripts and captions for audio and video content. The ADA requires that public-facing digital content be accessible to people with disabilities, including those with hearing impairments.
What's the difference between captions and transcripts?
Transcripts are text versions of audio content, typically displayed separately from the media. Captions are synchronized text that appears on-screen during video playback. Both are important for accessibility—transcripts for audio content and captions for video.
What caption formats does Sonix support?
Sonix exports captions in all major formats including SRT, VTT, SCC, DFXP, and more. These formats are compatible with YouTube, Vimeo, Facebook, and professional video editing software like Premiere Pro and Final Cut Pro.
How accurate are Sonix captions?
Sonix is independently reviewed as the most accurate automated transcription service. For accessibility compliance, we recommend reviewing captions before publishing. Our in-browser editor makes it easy to correct any errors and ensure quality.
Can Sonix create SDH captions?
Yes. Sonix supports speaker identification and you can add sound descriptions to create Subtitles for the Deaf and Hard of Hearing. SDH captions provide additional context beyond spoken words, such as [applause] or [music playing].

I was especially impressed with the quality when it comes to other accents as most other companies can only give a good machine transcript if it is a US accent. Sonix is amazing and I have nothing but good things to say. Thank you for providing this service!
