Sign language is a pretty good option. There will be times when access to the technology used to produce her voice might be inconvenient or even unavailable. American Sign Language (ASL) is also probably much faster than typing in a lot of cases. I grant, this probably won't be as helpful out in the world where most people won't understand it, but in the comfort of home, being able to converse at the dinner table without a keyboard at your side might be preferable. I suggest you don't ignore this as a supplimental tool.
