Read words or blocks of text aloud when highlighted or clicked

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 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 reads words or blocks of text aloud when they are highlighted or clicked, giving people with cognitive disabilities and/or low vision control over the sections they would like to hear spoken aloud.
