Captions enable people who are deaf or hard of hearing to follow media content, although they can be beneficial to everyone. Captions are a text display of dialog and narration and are written in the same language as the audio (subtitles, on the other hand, are a translation of the audio into another language). They also contain important non-speech information, such as sound effects or speaker cues.
Most of the paragraph repeats what is already on the prior page, and seems superfluous. I suggest cutting out the first two sentences to just:
"Captions contain narration and important non-speech information, such as sound effects or speaker cues, in the same language as the audio."
