Well I don't think so:
Eruption: Camerupt --> Torkoal
Sleep Talk: Whismur --> Torkoal.
Camerupt can't learn sleep talk through breeding, so you couldnt breed a Sleep Talking, Erupting Camerupt with Torkoal.
Although, You could get a Torkoal with Sleep Talk and Breed it with a Torkoal that has Eruption. I'm not sure if that works, though.
Meh, I tried helping ^^
