Mario Fux is looking to drive some new life into Simon speech recognition for KDE. For getting things going, Mario is looking at doing a final release of Simon that uses kdelibs4 and Qt4, following that the development focus will shift to making use of KDE Frameworks 5 and Qt5. There are already commits since 2013 to the KDE4/Qt4 version of Simon, warranting a release.
Mario is looking for interested KDE users to help in testing out new Simon code and other development help. More details via this blog post.
