[Student-projects] GSoC project on Language model and Acoustic model for Malayalam language for speech recognition system in CMU Sphinx

[Khyathi Chandu]

Hi,

I want to work on "Language and Acoustic Model for Malayalam in CMU Sphinx".
Where do I need to try and fix bugs. I have submitted my application. What
do I have to do now?

Thank you
