I just Stumbled Upon this tool called UJAM, which takes vocals and actually adds appropriate background music. I decided to push the envelope by simply just reading the instructions to one of the recent assignments that I did with one of my classes to see what it could do with spoken word. I think that it ended up doing very well. I would definitely use UJAM in the future to read instructions to students in an online class. I might not pick the same musical-style (Yes, you get to pick), but hopefully you can see where I am going with this.
