Extension:Wikispeech

The Wikispeech project aims to create an open source text-to-speech tool to make Wikimedia's projects more accessible for people that have difficulties reading for different reasons. Wikispeech will be available as a MediaWiki extension. More information can be found on the project page; this page is just about the Wikispeech extension itself. Stable release is planned for 2017.
