This feature involves a text-to-speech engine that reads the text on a web page aloud. This may be implemented in a number of different ways - as a built-in text-to-speech reader in the operating system, as downloadable screen reader software (including OCR software to access image of text) that operates on the user's machine, or as a remote text-to-speech service that receives text online and returns a spoken copy as an audio file.

The way that text is read may vary depending on the implementation and the user group. This approach simply reads the entire text of the page aloud and works in conjunction with simplified navigation techniques of screenreaders.
