Closed Captioning Accuracy Improvement with AI
Improving AI caption accuracy means feeding systems examples of what good captions look like in context, letting them learn that sports broadcasts need different nuance than interviews, and building in uncertainty detection so the system flags uncertain passages for human review. Small improvements here ripple outward to thousands of viewers.

Standard automatic captions often fail on accented speech, technical vocabulary, and overlapping voices.
