I don't know if this is the same thing I got email about, but there's something called Dictate that is a plug-in you can use with earlier versions of Word. I haven't tried it myself, but it looks like it's worth checking out. One of the nice dictation features for poets appears to be the "new line" command.

By the way, I find my Android phone's native voice recognition to be amazing. I often dictate emails and texts and Google search requests, and the accuracy is incredible. It's come a very long way since just a few years back when voice recognition required lots of voice training and was clunky at best. I still write, though, at a full keyboard since I'm very comfortable writing that way.
