What are scrolling captions?
Scrolling captions are produced by highly skilled stenographers using shorthand machines to type captions as the words are spoken (eg a live-to-air interview). These are the most specialised form of captions there is no time to edit or ask a speaker to repeat phrases or unfamiliar words. Where required, phonetic spelling is used and minor contractions are used when the speaking speed is fast (usually 200+ words per minute). Accuracy of stenocaptions is expected to be 98%.
