Adding voiced random encounters in Skyrim

I am wondering how I can add random events such as “College Application Denied” and “A Good Death” with the Creation Engine.

I looked for tutorials on this, but couldn’t find anything specific. I used the Creation Engine to replace 3d meshes and use them as activators for some small scripts, but beyond that I didn’t do anything.
