Text to speech in digital television

Text to speech in digital television refers to digital television products that use speech synthesis (computer-generated speech that “talks” to the end user) to enable access to blind or partially sighted people. By combining a digital television (a television, set-top box, personal video recorder, or other type of receiver) with a speech synthesis engine, blind and partially sighted people are able to access information that is normally displayed visually in order to operate the menus and electronic program guides of the receiver.
