Q: iphone screen does not respond to touch, voice speaks time and date

Try a reset: hold sleep/wake button and home button until Apple logo appears.

You have somehow enabled Voice Over, a feature for visually impaired users. See: http://support.apple.com/kb/HT5018, "Managing accessibility functions using iTunes"

You can also access it on the phone. Anywhere you would use 1 tap, use 2 taps instead.
