What aspect of accessibility do subtitles specifically address?

Subtitles specifically address the need to convey spoken content through text. They are designed to provide a written representation of the dialogue and other audio elements in a video, allowing individuals who are deaf or hard of hearing to access the narrative and information present in the spoken dialogue. This form of accessibility ensures that those who cannot hear the audio can fully engage with the content, promoting inclusivity and understanding.

By translating spoken words into text, subtitles also often include descriptions of non-verbal sounds that add context to the scenario, such as music or sound effects, further enhancing the viewer's experience. This essential function of subtitles makes them a vital tool for accessibility in multimedia content. Other aspects, such as visual transitions or enhancing video resolution, do not directly relate to the purpose of subtitles in fostering understanding through text representation of audio.
