According to research conducted in the United Kingdom (2006), once a user becomes aware of closed captions, their utility is universal. The following are just a handful of the advantages of subtitles:
---Closed captions (CC) help viewers who speak English as a second language because they make it simpler to follow up with the speech.
---CC aid in the understanding of speech delivered rapidly, with accents, muttering, or in the presence of background noise.
---CC includes complete names, brand names, or technical jargon and clarifies the situation for the audience.
---CC assists viewers with learning impairments, attention problems, or autism in maintaining focus, which may result in a more positive viewing experience.
---Online videos with subtitles have a greater level of user engagement and provide a more positive user experience.
---Captions enable users to see films in noisy settings such as offices and libraries.
