How to turn voiceover off if it is locked with a passcode?

I have an iphone 4 and i missing with it and accidentally turn on the voiceover option. I've tried using my passcode but it is not working with the voiceover option on. I have tried clicking the home screen 3 times fast but it does not disable. What can I do to disable this.

Hold the home and sleep wake button at the same time and it will turn off then turn it back on and voice over will probably still be on and if it is press it three times the home button and if that doesn't work talke it to apple. Just keep trying with the trying to turn it off.
