VoiceType!! Now that's a REALLY cool feature included FREE!! in OS/2 Warp 4. You can now talk to your computer.
You can dictate all the words you wish, and when you're finished, you can right click on any wrong words and you will hear yourself. Then you can judge if you want this word to be spelled differently for the way you just said/heard it. This doesn't mean that you delete the previous word, but the way you spoke it will reflect the new setting. This also allows you to add and concat words.
You can also navigate all over your Desktop, learning macros and "jump to"s to the computer and have them optionally displayed speaking the names of the help windows if you don't know what to do!
