help for a beginner on the IPhone5S

Hi members. I am completely new to the IPhone. I have the IPhone5S. I struggle a lot to navigate the screen. I cannot get to the home screen containing all the aps such as phone, mail etc. voice over constantly tells me Iphone disabled. I use my right index finger to navigate the screen. AS I drag my finger on the screen I get to an unlock button. I double tap this and voice over tells me to enter a pass code. I managed to enter digits by double tapping a number. so I entered 4 digits. but I can't find a button to ok the pass code. I can only find a cancel button. And there is something else that confuses me. I hear 2 voices: I hear the english voice over voice but then I also hear a foreign language voice; it sounds like french. Your help is much appreciated.
