cannot unlock my iphone 5

Hi theklalouca,

Welcome to the Apple Support Communities!

It sounds like the VoiceOver feature has been activated on your iPhone. You can disable this by connecting to iTunes on a computer. The steps are provided in the following article.

2. In iTunes, select your device.
3. From the Summary pane, click Configure Universal Access in the Options section at the bottom.

I hope this helps,
