Audio description at scale: 50,000 videos in seven months

Top-tier publishing clients were under pressure to comply with ADA and WCAG accessibility standards for thousands of educational videos. Nexority was engaged to deliver high-quality audio descriptions at scale, without compromising on voice quality, accuracy or deadlines.

• Voice talent limitations: a scalable solution had to maintain consistent quality across every narrator.
• Massive volume: over 50,000 videos required narration within just seven months.
• QC burden: manual validation was not feasible at that scale.

• Hybrid voice workflow: professional narrators combined with AI text-to-speech for a consistent tone.
• Automated QC pipeline: AI-based detection of errors, with human review of samples.
• Project tracker: visual dashboards giving the client real-time status on every batch.

• On-time delivery: the seven-month deadline was met.
• 98% accuracy across all video descriptions.
• Compliance achieved: the content now meets global accessibility standards.
