I have the exact same problem as morganbren. This happens in both Tower 2011 and Tracon 2012 running on Windows 7. After a while (usually within minutes), the speech recognition gets stuck on "Listening" and the PTT button in the simulator gets stuck. The only way out is by killing both the simulator and the speech recognition with Task Manager. It definitely feels like the speech recognition crashes first, as the simulation usually works for a couple of seconds even after the recognition hangs.
Any solutions for this problem?
