Voice commands, only? Really?
I'm a quadriplegic and would not be able to touch this thing after someone placed it around my neck. Would I be able to use it?
Maybe, and I say maybe because if someone call you, unfortunately you wouldn't be able to press the phone button to accept the phone call. However, there are other options. If your phone or device has auto answer when someone calls, then I think they would work for you. Hope that answered any questions you had...... Have a great day
