Text-to-Speech in Digital television refers to digital television products that use speech synthesis (computer generated speech providing a product that “talks” to the end user) to enable access by blind or partially sighted people.By combining a digital television solution (a television, set-top box, PVR or other type of receiver) with a speech synthesis engine, blind and partially sighted people are able to access information that is displayed to other users visually on the screen and therefore can operate the menus and Electronic Program Guides of the receiver.
