A good microphone makes a world of difference when it comes to dictation. If you want to dictate effectively and accurately, you cannot rely on the built-in mic that is found in a computer. Instead, you need to have a microphone that is very close to your mouth, preferably approximately an inch away.

There are various ways to test the microphone and to test its accuracy. Your mileage may vary but I think everyone has to find that which is good for them. With Dragon, there is an approved list that is posted on their website.

I found three types of microphones. For me, headphones seemed to be the most convenient because it goes where your head does and the microphone stays close to your mouth. Others, use a desk type microphone and bring their mouth to the mic. The third is a microphone that is found built into a camera -- such as a WebCam -- that you might be able to bring closer to your mouth.

Amongst headphones, I find two varieties: standard audio card, and USB. The audio card variety is easily found, but my experience has been that the USB mics work better. They have a built-in sound card within them and their audio signal goes directly to the motherboard, without using the computer’s soundcard.

I found a very good one from a company called Jabra. You can google them and see their various models. Good luck at it!
