In the mean time, I posted some speech recognition stuff to the lfs
website under the asr directory in the download section.
it contains a perl script to run sphinx2 and sent the text to an IP, the
language model files, and a small c program to parse the text output
created by sphinx. If you think about it the ATC language and grammar
(aside from motor-mouths) is fairly concise, precise, and structured;
even sparse in terms of volume -- at least on a per aircraft basis. You
can get the binary package for Debian or start with the source from CMU.
IMHO a flightgear feature that would be a barn-burner would be speech
recognition coupled with festival. Throw in an AI based set of
controllers and you could have a VATSIM/IVAO capability 24/7 as well as
the multiplayer stuff
You could use ops research concepts to route
aircraft and maintain separation and control aircraft (either AI or
human controlled) to a final approach metering fix. In fact there is
ongoing research in the area of 4D trajectories. seems this would be a
natural for guys like Dave and Durk.
Back to Curt ...
The whole idea of having a speech recognition engine understand your simple commands seems like a really interesting idea to explore. Beyond automated ATC, there is a whole host of human/machine interaction issues that could be explored. How about a voice activated flight director for real R/C pilots ... the computer could give hints to the pilot on the ground for flying a perfect approach down to landing, and the R/C pilot could give voice commands to request specific data, or switch the systems to different modes.
Regards,
Curt.
