It is now more than a year since Multi Crew Experience, voice control add-on to FSX and FS2004 has been released. “….. The FS++ team is pleased to announce the release of Version V2.0 of their award winning add-on. This release allows you to create your own commands and more. Also, support for Radar Contact ATC voice interaction has been added….”.
“…. MCE is a speech based add-on that allows the flight sim enthusiast to fly those heavies in a more realistic way. Issue commands to co-pilot, go through the checklist, etc. You can also interact with the native FS ATC entirely by voice. There is more to this add-on than meets the eye.
A fully working, time limited demo, is available from simMarket here.
