Hi Ted, It's great to hear that voice recognition in Ubuntu is finally getting some love :).
The English Voxforge models are currently packaged in julius-voxforge. There I did go with the nightly builds there, since in addition to the time and disk size (which IMHO is already enough of a reason), it needed HTK to build, which is not redistributable. It'd also be interested in more opinions though. Out of curiosity, what's the plan for voice recognition in Ubuntu? Sphinx/Julius/Kaldi? Regards, Siegfried Am Montag, 25.
