The basic format used on the Web is called HTML. The intelligence built into pwWebSpeak understands the HTML constructs and automatically presents them in a logical sequence, greatly simplifying navigation of even complex documents.



Emacspeak is a speech interface that allows visually impaired users to interact independently and efficiently with the computer. Audio formatting –a technique pioneered by AsTeR– and full support for W3C’s Aural CSS (ACSS) allows Emacspeak to produce rich aural presentations of electronic information.

By seamlessly blending all aspects of the Internet such as Web-surfing and messaging, Emacspeak speech-enables local and remote information via a consistent and well-integrated user interface.
