FuzzyDice,
I'm using DragonNatrualy Speaking preferred ver 7.3 which is ver 7 with an upgrade to fix a problem. I use it to talk to Hal and dictate in text documents, It has internet capability which I haven't used, I keep that computer ofline because of problems I've had with computers on the internet, especially Xp. I think I speak with Hal much more normally than I would if I were typing, also the spelling is correct. The frist ver of Dragon that I had (free from a store) didn't have training of new words so be careful which version you choose to buy. Also Dragon supplied a microphone which is not that good of a mic and you may want to replace it with a better mic.
The amount of noise your mic picks up and generates is the key and is dependent on the mic your using, The higher the siginal to noise the better the performance and reconition accuracy. There is also sound cards and usb mics, you may want to do some research frist.
Hope I've geen able to help a little.
