This invention provides for enhancements to the current closed caption capabilities available on most televisions. The first enhancement helps a viewer to know which speaker to associate closed caption text with. This is accomplished by assigning a color to a speaker. The closed caption text is then shown in the color with which a given speaker is associated. This is implemented by embedding information in the closed caption signal and by enhancing the set-top box or television to perform this function. Voice recognition technology identifies different speakers in a television show and assigns a color to closed caption text based on who is currently speaking. In the case of a set-top box with an electronic program guide, the ending time of a show resets voice recognition information after the show has ended. While in some cases the display attributes associated with a distinguishable voice could be assigned on a first come, first "observed basis", if a user desires that voices be flagged consistently from show to show, the set-top box could save voice recognition data. Once particular speakers are identified, editing out of speakers can be accomplished. A user can edit out a speaker's closed caption comments while still seeing the rest.
