iPhone 4 automatically turned on voice control from IOS 6 how disable Phone not working properly and cannot get all options under section Please help

iPhone 4 was updated to new IOS 6 as soon as it became available, now voice control turned on out of nowhere and I am unable to turn it off! I cannot scroll past initial options within each section, especially Settings. How do I disable the Voice Control and maintain normal control over phone? Is this another issue? I am begging for help since I can't do anything but turn phone on after turning it off, unlock phone and click settings option. Additional problem is phone has not been back up to iCloud in about 1 month because it states I have no memory--my gmail is synced to iPhone and has about 9,000 emails I am attempting to delete. (That is secondary problem)

PLEASE HELP ME DISABLE VOICE CONTROL AND REGAIN OWN CONTROL ON PHONE!

Thank you more than ever!!
