I use the SPEECH recognition sometimes. I'm using it right now for this post.
It wants to highlight words on the page instead of typing them, like SPEECH. So instead I spell the word and that is why the word SPEECH is capitalized.
I have read the more you use it the better it learns your voice.
It has an 80% success rate or so for me. I like it if I'm going to be typing a lot!
One thing that I did not like is that I had to use Internet Explorer for this example. But I won't be using it surfing the web anyway.
