Textual representations of audio content displayed on the social media platform provide accessibility for viewers who are deaf or hard of hearing. This functionality also aids individuals watching videos in noisy environments or those who prefer reading along with the dialogue. For instance, a user viewing a recorded live stream can enable these text overlays to follow the conversation even if the audio is unclear or muted.
The availability of synchronized subtitles enhances inclusivity, broadening the potential audience reach for content creators. Furthermore, these textual aids can improve viewer engagement and comprehension, especially for complex or information-dense material. Historically, incorporating such features was a manual and often time-consuming process; however, advancements in automatic speech recognition have streamlined their generation, making them more readily available.
