Thanks for your reply James. Nice to see your prompt response, i am assured VoxCommando is one of the top noch softwares in the market today. You are true about external factors affecting the effectiveness of voice commands and microphones reception. I just want to be sure that whatever technology is present today I am able to take full benefit of it, am sure in the future there will be more add-on hardware's available in the market that will identify human sound and automatically reduce the sound of audio on the speakers.
I have spent a couple of hours going through this entire microphones section of the forum, including the wiki.. having understood my requirement.. i realize that an open mic, such as the array microphone will be best suited for my scenario. I did some research on the internet to see what people use with dragon speech recognition (as a lot of people use them for writing novels and all), i see multitudes of product, and one product does stand out is "Acoustic Magic Voice Tracker I Array Microphone". I dont see anyone has posted their experiences about this product with voxcommando, however i am planning to drop the ball on this, and if it does not turn out to be that good i can always return it and get something else.
The list of universities in here does say that the product is capable enough. Also many govt agencies use it too.
