PLEASE CLOSE-------Total voice control for blind/low vision people on android

Does anybody know of an app or hack/mod that gives total voice control for people of low vision/blind?
I'm trying to find such a thing for a friend who wants to get an android tablet but this seems to be the biggest drawback- no apps that do this. I have found some that mainly do voice and texting but nothing to the extent of total voice control.
Now by voice control I mean something that can be activated by a short press or double press of the power button or volume keys etc.
Please no smart ass remarks. Regardless of a persons ability to see or not, they should be able to use a device if they so choose.
Thanks for any help in advance.

you are evolutionary success, act like it
