Captioning services provide text representations of spoken dialogue and sound effects in videos, films, and live events. These services are essential for making content accessible to individuals who are deaf or hard of hearing. Captions can be either open, meaning they are always visible, or closed, allowing viewers to turn them on or off as needed. In addition to accessibility, captioning services enhance comprehension for all viewers, especially in noisy environments or when the audio quality is poor. They are commonly used in various media formats, including television, online videos, and educational content, ensuring that information is conveyed effectively to a wider audience.
