Voice recognition and dictation

I have started to use some recognition software on my Mac. In the hope to make the mac get dictation: emails, proposals, you name it. It's a little difficult to train the software to learn and recognize my speech. And the program is a bit buggy, it stopped responding a couple of time. Also it forces you to use SpeakPad (a little notepad) to do your dictations, before copying them in other programs. But these are still details if the software works. And in fact it does. I believe that perseverance will make the difference. My choice went for IBM Viavoice software, which was not too expensive. I do hope that it will allow me to SAVE TIME, altogether. If it doesn't there won't be any real use. Time will tell.
