This project looks promising and worth supporting.
“The aim of “Project metalmouth” is to develop a fully functioned (although initially basic) open source voice browser – which sits inside the Chrome browser as an extension. The ambition is to give users, who want to use this extension, the best possible user experience when interacting with the spoken web.
Please read the ‘GettingStarted’ wiki guide. Otherwise, if you are interested in the project or want to get involved there is an official project blog – http://projectmetalmouth.blogspot.com/. This blog tracks the direction of work on this project and is intended as the easiest entry for anyone wishing to take part in the project.
Finally, if you are using the extension or just like the intensions behind the project (I already like you and think you’re wonderful) I would ask you to get involved in the project (especially user testing, feature requests, etc…) – otherwise, maybe just providing a link to the project website (http://code.google.com/p/metalmouth/) so that others may more easily find it.”
