VLC is a free and open-source media player which runs on a variety of operating systems including Windows, Mac OS X and Linux. VLC supports closed captioning, a system of displaying text for the hearing impaired which summarizes the audio in a media file. Closed captions are distinct from subtitles in that they include more information than just the spoken words and are implemented differently than plain-text subtitle files. VLC supports enabling closed captioning support and selecting it on a per-file basis from its menu.
Download and install the latest version of VLC from the official website, if you don't already have it (see Resources). Older versions of VLC don't have closed captioning support.
