I'm attempting to set up the speech recognition function built in to windows 7, to control ATC communication on my flight simulator. Does anyone know anything about this novelty feature that never gets used? Audio set up details: Default audio device is a 7.1 surround system with a dedicated sound card. Default communication device is an external USB dongle with my headset plugged in to it. The speech recognition feature only seems to work with the "default audio device". If I switch that to being the external doodad, it works fine. Anyone know if it is possible to get the SR using the headset, while everything else is still through the speakers? I feel like I'm missing some obvious step here. Cheers guys.
