Well, the most interesting question here for me is what about licensing 
such language models -- could they be considered to be firmware 
(redistributable, not modifiable)?

This is important also because of their size (shipping 1G+ corpora, even 
compressed, is probably not a right way to go).

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

They are not firmware, but are they "content"? Non-code "content",
e.g. game
data, is allowed under the same rules as firmware. On the other hand, this
does not apply for things like fonts or documentation.

Yes yes, that's what I meant by "considering to be firmware"...thank you 
  Kevin for clarification.

What's the (juristic) difference between game data and speech 
recognition data (or in common any scientific appplications data)?

This is a common situation in many scientific apps (especially natural 
language processing): the code is not important (and thus released under 
GPL or whatever else), what matters is data (thus if released, then only 
in binary form).

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

Plenty of them. I forgot which ones exactly. Just check a few of them and
I'm sure you'll find some. Or ask the Games SIG.

Ah yes, we do have some content which are just distributable.
