Audible app voice commands

[Lulabirdy10]

I have a Sony Xperia Z2 and I love voice commands. I use Utter mostly but sometimes GoogleNow. I'd really like a voice command that will open the Audible app (audiobooks) and start playing the book I indicate. Right now, I have a voice command to open Audible but nothing that will start the playing of a specific book. Does anyone know of any commands or any apps I can use to accomplish this? Any help you can offer would be appreciated. Thanks!
