I've created a voice-controlled web browser for Android called Speech
Browser. As well as obviously reading back the pages, it is all
controlled via speech. It has all the functions of a standard web
browser, such as going to a URL, searching for text, going through
history, following links etc.... I've also added some shortcut
functions for searching with all the main search engines and
wikipedia, and you can also control the speed of the speech as it is
read back.
The market URL is
