Narrator is a text-to-speech utility for users who are blind or have impaired vision. Narrator reads what is displayed on your screen: the contents of the active window, menu options, or the text you have typed.
Narrator is designed to work with Notepad, Wordpad, Control Panel programs, Internet Explorer, the Windows desktop, and Windows setup. Narrator may not read words aloud correctly in other programs.
Narrator has a number of options that allow you to customize the way screen elements are read.
The accessibility tools that ship with Windows are intended to provide a minimum level of functionality for users with special needs. Most users with disabilities will need utility programs with more advanced functionality for daily use.
