Check the Google Summer of Code project blog for at least weekly updates. Both of this week's updates from the two GSoC students are posted. Among many other things, Ronanki coded an edit distance scoring grammar generator based on neighboring phonemes, and Troy measured the automatic intelligibility versus bit rate bandwidth of the Speex vocoder at various quality levels.
The first code check-ins are available from launchpad (using the Bazaar source code control system) and subversion. The current to-do list in on the project wiki, while the original milestones are on SourceForge. The students are already weeks ahead of their original schedules.
