With standard browsers common tasks such as selecting links on a web page, filling forms and performing searches are best performed using a combination of mouse and keyboard. For people who can not use these devices using the Internet is hard if not impossible.

CanSpeak is a customizable interface that uses speech instead of mouse and keyboard for web navigation.

To enter a letter a corresponding keyword has to be uttered. The list of keywords can be customized for each user so the system is usable for people with speech impediments or accents.

To select a link or element on a webpage, the user will have to start saying the letters in its label. Analysis of web pages has shown that with our labeling scheme most elements can be selected after saying two or three keywords.

CanSpeak is built on top of Key-Surf which is an interface that allows the user to select elements on a webpage using keystrokes rather than the mouse. Key-Surf was developed by Leo Spalteholz under the supervision of Dr. Nigel Livingston at CanAssist at University of Victoria. I developed the speech module used in CanSpeak at CanAssist under the supervision of Dr. Livingston and Leo Spalteholz. We used Carnegie Mellon University's open-source Sphinx-4 speech engine.
