I just recently purchased FS2Crew for the FBW a320 and I absolutely cannot get voice recognition to work. I have done every single fix on the FS2crew help section, including uninstalling, reinstalling fs2crew, changing languages, changing hardware, and so on.
FS2Crew is a series of add-ons created to provide a more realistic flying experience. The main focus of the add-on is to simulate flying with the first officer, and it is capable of recognizing voice commands and performing checklists and procedures. This simulation replicates an experience of having a copilot, enabling users to actively engage in checklist completion and control manipulation, thereby heightening the overall realism of the flight.
As someone who is still having major issues with speech recognition in Pilot2Atc (my voice works fine with W8 voice control and other utilities like FS2Crew and VoxATC), I think Moontan's button suggestion is the way forward.
Speech Recognition
Command the First Office to set the flaps, gear, autopilot, takeoff thrust, and execute the flows and checklists. See the Voice Command section for a full list of commands
Checklist can be controlled via voice or completely automated
Control Push Back via Voice commands
