Finding Qualified CART Captioning Providers for Accessible Live Events
Communication Access Realtime Translation (CART) remains the gold standard for live event accessibility. Unlike auto-generated captions—which typically achieve 70–85% accuracy—professional CART captioners deliver 98%+ verbatim accuracy using stenotype machines and specialized software, making them the only reliable option for technical content, legal proceedings, and events where every word matters.
Why CART Over Auto-Captioning?
The ADA requires "auxiliary aids and services" for effective communication. While WCAG 2.1 Level AA mandates live captioning for video content, automatic speech recognition (ASR) rarely meets the accuracy threshold considered an appropriate accommodation. Courts and the Department of Justice have consistently interpreted the ADA to require human-quality captioning when requested.
Key Selection Criteria
- NCRA Certification
- The Certified Realtime Captioner (CRC) designation from the National Court Reporters Association validates 180+ WPM realtime proficiency. Historically, there were separate CBC and CCP certifications, consolidated into CRC in 2016.
- Remote vs. On-Site
- Remote CART has become the industry norm post-2020, reducing costs by 30–40% without sacrificing quality. On-site remains essential for events with complex audio environments or multiple speakers without individual microphones.
- Technical Integration
- Top providers integrate with Zoom, Microsoft Teams, Webex, and custom streaming platforms. Look for providers offering StreamText or similar browser-based display solutions for in-person events.
Industry Landscape
The CART captioning market includes established firms with decades of experience alongside newer entrants leveraging hybrid human-AI workflows. Notable consolidation occurred in 2020 when AI-Media acquired Alternative Communication Services (ACS Captions), and VITAC—the largest U.S. captioning provider since 1986—became part of Verbit. Caption First, founded in 1989, has captioned events in 45+ countries. Family-owned firms like HRI-CART (est. 1992) continue to serve niche segments with personalized service.
