Which electronic device allows the hearing impaired to understand the dialogue of television programs and movies?

The closed caption device is specifically designed to assist individuals who are hearing impaired by providing a text representation of the dialogue and sound effects in television programs and movies. This feature displays the spoken words as on-screen text, allowing users to read along while watching a program. Closed captions also often include descriptions of important non-verbal sounds that enhance the understanding of the content, such as music cues, sound effects, and speaker identification.

In contrast, hearing aids primarily amplify sound to help individuals hear better in a variety of situations but do not provide textual representations of dialogue, especially not for visual media like television. Assistive listening devices can enhance audio input in specific settings, such as lectures or performances, but do not specifically serve to convert dialogue into text. Coil receivers are typically used in conjunction with hearing aids to connect to certain sound systems but do not directly provide text for understanding television programs.
