Accessible experiences rely on precise, fast, and nuanced closed captions (CC) and subtitles for the deaf and hard of hearing (SDH). Ollang’s agentic AI makes it happen.
Here’s how content owners and localization teams meet North American standards like the Americans with Disabilities Act (ADA) and the Accessible Canada Act (ACA) with ease and deliver compliant, high-quality captions and subtitles without bottlenecks.
What is CC and SDH?

CC refers to the text overlay on video screens that transcribes spoken dialogue and non-speech sounds, such as sound effects and speaker identification.
SDH extends beyond simple captions by including detailed descriptions of ambient sounds and audio cues.
For deaf and hard of hearing viewers, closed captions and SDH are essential. And content owners need to step up to meet compliance and accessibility standards.
That’s where Ollang comes in with its agentic localization system, which provides near-error-free CC and SDH (95%+ accurate) so industries can create inclusive, high-quality content without the struggle.

Video Content Accessibility in ADA, CVAA and ACA Laws

Key laws in the US and Canada require features that make videos accessible for everyone, including those with hearing impairments.
Key US Laws: ADA and CVAA
⦿ Americans with Disabilities Act (ADA): Businesses must provide accurate captions and SDH for online videos. Many follow the WCAG 2.1 AA guidelines to create ADA compliant closed captioning.
⦿ 21st Century Communications and Video Accessibility Act (CVAA):
This law focuses on videos shown online after appearing on US television. Accordingly, the original TV closed captions must be included in the online version.
Canada's Commitment: ACA
⦿ Accessible Canada Act (ACA): The ACA works towards making content, including videos, fully accessible across the country.
