What worked for me was my neighbor holding down the both volume control buttons for a few seconds. Every other suggestion did not work. I do not even know how it came to be on. I could turn the phone off by holding down the home button and the one on the top of phone, but when turning it back on voice control was still there. I could not get into the phone at all, the screen lock comes on automatically and no amount of any sort of attempt to open it in any manner worked. I owe my neighbor a beer!!
