VoxATC - Replacement for FSX default ATC with voice control

When talking about aviation, one of the key persons besides the pilot, that helps ensure a safe flight, is the air traffic controller. Therefore having a realistic ATC is important for an overall realistic simulated experience. Unfortunately many flight simmers are not really happy about the ATC that comes built in Flight Simulator X, especially when flying state of the art  planes with FMC that supports SID/STAR. Also especially on mountain airports like LOWI default ATC keeps vectoring the pilot straight into mountains.

One option  for a better air traffic control experience is joining one of the online communities like IVAO or VATSIM. Even there there are not always ATC connected and if you are living in some areas of the world with less coverage you might end up doing the flight alone.

Luckily there are a few ad-dons that successfully manage to replace the built in ATC of flight simulator and improve the overall experience.

Online ATC simulator game

ATC-SIM is a very realistic online ATC simulator, with and interface which resemble a real ATC screen, that can help you get rid of boredom.
It also has a scoring system implemented to see where you rank between the fellow controllers, and various airports you can control on.
The only downside I found is the fact that you need to learn all those text commands to control the aircraft, but if you print them and keep them on your desk, they are not that hard to memorize with time.
