Abstract
Automatic subtitles are widely used for subtitling television and online videos. Some include punctuation while others do not. Our study with 21 participants watching subtitled videos found that viewers reported that punctuation improves the “readability” experience for deaf, hard of hearing, and hearing viewers, regardless of whether it was generated via ASR or humans. Given that automatic subtitles have become widely integrated into online video and television programs, and that nearly 20% of television viewers in US or UK use subtitles, there is evidence that supports punctuation in subtitles has the potential to improve the viewing experience for a significant percentage of the all television viewers, including people who are deaf, hard of hearing, and hearing.
