AutoVoice Is it better for Autovoice to run on a tablet or a cell phone for GH?

I have Autovoice on my phone and recently duplicate all the settings onto a wallmounted tablet that I use for my Home Automation and reassigned Join/Tasker/Autovoice to route through the wall mounted tablet.

Now that Autovoice is supported by GH, was wondering if I'm better off having GH run through my phone or keep it on the tablet.

I guess if I run it off the tablet, text message and calling wouldn't work but I also don't need the wife to be sending call commands and have it dial through my phone.
