The document summarizes research on the effects of faster subtitle reading speeds. An experiment tested comprehension, cognitive load, and preferences with slow (12 cps) and fast (20 cps) subtitles in Hungarian and English. While slow subtitles required more text reduction, fast subtitles provided higher fidelity to the original dialogue. Participants generally preferred faster subtitles that contained more text, though slow subtitles were re-read more. Viewers wanted subtitles to match the dialogue accurately in order to fully understand the content and learn languages.
