That's a really tall order.
There is no way to do speech recognition with Flash internally, but
you could use the audio recording capabilities connected to a media
server. This would then have to process the recorded audio with a
server-side speech recognition service that would pass a command back
to Flash. It would be anything but real time... but depending on the
performance of the speech recognition service could be usable.
As far as the service goes... there are very few speech recognition
options. IBM's ViaVoice was just discontinued for Linux. In the open
source world, I think all that is left is CMU Sphinx project.
Very custom, but it would probably go something like this:
Flash
AS3 connect to Red 5 media server
record audio to server-side file
associate file with job id
server hands file off to Sphinx speech to text service
text processed and matched to list of known commands with something
like soundex
command recorded to job id
Flash polls server for response to job id
Flash does some action based on command form response
So really custom and not at all trivial. However it is pretty
interesting ;)

Has anyone experimented with speech recognition engines and AS3??
Any suggestions as to where to start? I am working on a game for
primary grade students who can't read well yet, and would like to
let them interact by speaking to the application. The app will need
to recognize their spoken responses.
Thanks for any insights!!!
