The FS++ team has just updated the voice control add-on for FSX & FS9 to work with the PMDG 737NGX via the SDK. Get your virtual co-pilot to flip those switches on voice commands. Fancy doing things the professional way, let the co-pilot perform a chain of actions in the order and pace you choose, all triggered via a single voice command. Talk to native FS ATC or Radar Contact ATC. A Demo is available for download.
