Abstract:

Many people find it difficult to read from a computer screen - especially visually impaired users, and those with reading difficulties such as dyslexia. Many people print pages out to read them later, which isn't very efficient in terms of time (as well as paper consumption). Unsurprisingly, a number of 'read aloud' applications are emerging for web sites.
