Dictation Software for Linux?

Yottabyte84 asks: "As a student, I often have the need to type up papers, however like most people I talk faster then I type. I've lately been looking to get a dictation program, but I don't wanna boot Windows every time I need to use it. IBM has a commercial version of ViaVoice for Linux and a free SDK. I'm unclear what the SDK can do, and would be willing to buy the commercial product if the SDK doesn't fit my needs. What I'd really like to be able to do is give spoken text input into the Linux apps I already use, but could live with being stuck with a simple included word processer. Have any of you tried ViaVoice or the SDK? How well did they work for you?"
