I've tried (Windows') speech recognition some time before, and I know
it's one heck of a mess trying to type anything with it. I have a fully
working hand, so I don't actually need a voice recognition, but I
remember trying to write a single (not code) paragraph solely by
recognition. It took me over an hour correcting all those mistakes and
it really starts to gets into the nerves after the first sentence. I did
a little victory dance, after doing the first paragraph.
I know they gets better with time as they learn our speech pattern and
we learn how to pronounce the way the voice recognition expects. But one
thing I can't imagine is using voice recognition for writing code
(heck... that'll be a nightmare inside a nightmare)

Maybe we need an editor that could sort of understand something like:
and apply the appropriate code-sensitive convention transformation (in
python it'll be RED)
"class foo inheriting object"
and typed "class Foo(object):\n\t"
put a tab or delete a tab (or softtab)
but for all those, we're going to need a specialized text editor or
perhaps a context-sensitive voice recognition software. The simplest
solution would be a vim plugin or emacs mode that is specially tailored
to recognize these commands and apply the appropriate transformations
depending on the contexts.

Personally, I think it'd be very difficult to try to change conventions
that were made for a job that requires so much typing. In programming,
typing is almost a requirement. I'm aware people will still try to
insist on doing things they love the most no matter what happens, but I
still think if the disabled want to program, they're the one that need
to adjust their work flow and definitely with the current voice
recognition technology, they really need better tools.

Stephen Hawking didn't stop with his experiments when his whole body
can't move. I agree that disabilities shouldn't stop people from
programming, which is mostly the head's job. I think if we can make
voice recognition faster and easier than typing (like in those sci-fi
movies), disabled or not we will all benefit from it. Maybe some day, we
all, disabled or not, might code with voice recognition and keyboard
will be considered obsolete.
