Which makes open source speech > recognition something not doable yet. There are some small databases available [1], although admittedly too small for accurate general purpose use. There are some models available [2], built from databases which are not themselves redistributable. There are also a number of model-building tools available [3-5], which may be sufficient for small command-and-control tasks. But you are right. For general-purpose voice recognition, we don't have the data we need. Still, I think it may be worth putting the software in place so that those who wish to purchase licenses to commercial data have everything else they need, and to encourage the production of better quality free data [6].
