This is going to sound really odd. But I finished a voice recognition program that runs simple computer commands when it hears words I say. It is implemented in a small room in my office. I don't want to wear a mic or carry a mic around to control the program (plus I want to impress the boss). Is there a microphone that is powerful enough to hear what I say no matter where I am in the room? I am guessing it would have to be something with a preamp etc. I just want to be able to give a command (I know I will have to talk loud, but i don't want the scream) and the mic relay the sound to my computer. I have tried normal mics and they don't even pick up if i am yelling. I don't want to spend more than $50. My program doesn't make any mistakes, so don't worry about background noise, it can sift through it. Thanks.
