Is anybody interested in working with me on getting some voice recognition product packaged up in usable form on Fedora?

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].

For speech recognition, software is only part of the problem and, fundamentally, the easiest one (take the algorithms, implement them, optimize/debug at will). The real problem is the data needed to build the models to feed the algorithms. There isn't as far as I know any reasonable set of corpus available under an open source license usable to build a decent speech recognizer. Which makes open source speech recognition something not doable yet. OG.

No. They are not firmware and cannot be considered as one.

I am not sure, any games are carrying non modifiable content. Which ones are talking about?

Does anybody know of anything more accessible than CMU Sphinx (it appears to be very powerful, but is definitely not for newbies; also, not all pieces of it have been released yet)?
