Another accessibility feature in Vista is the Narrator, which uses Text-to-Speech (TTS) technology to enable Vista to play back printed text in a pre-recorded spoken voice. This can be very useful for users with vision impairments and difficulty reading the text displayed on the screen. It can also useful for someone who is working on multiple tasks at one time.
Text-to-Speech in Vista is made possible through a built-in driver called the TTS engine that is able to recognize text. It can play displayed text back using a pre-generated voice.
To start the Narrator for the current session, click Start, Control Panel then Ease of Access. Under Explore all settings, select Use the computer without a display. Under Hear text read aloud, click the Turn on Narrator option and click Save.
