How can I get voice recognition features into the Unity Game Engine? Is there a pluginplug-in or a framework (hopefully freeware) that I could use? If so, do you have any ideas on how to install it? Also, how much of a problem would there be with background noises in the game interfering with the voice inputs into the game? Are there any examples of games on the market that use this? (besides for Spain 3d3D for the Torque Game Engine).
