Speech Browser! It's a voice-controlled web browser with all the usual functions that a web browser has, such as going to a website, doing a search, going forwards/back through history, following links, searching for text etc..
However, being voice-controlled, there are a lot of extra functions: repeating a page, going forward/back through the page, controlling the speed of the voice. There are also 3 voices available: British, American and Canadian (although being British myself I can't tell the difference between the last two :) ).
It should hopefully be quite useful for blind Android users (and if any find it useful or otherwise I'd be please to know), but I also wrote it for people to be able to listen to a website like Wikipedia without having to stare at a screen.
