If it is speaking, that means the voice over feature of your iPad is turned on. When it is turned on, you have to select the item/app and double tap the item to open it. You have use to three fingers at same time to swipe or scroll instead of using one finger. First, try this to turn off voice over.
Triple click the home button (round button at front bottom) quickly and this will turn the Voice over off. The three clicks should be very fast and there must not be any delay between the clicks. Or hold down home button and this will bring Siri. Ask Siri to "Turn off VoiceOver" i.e say "Siri, Turn off Voice Over".
If that didn't work, then you have to turn it off manually. Lock the iPad by pressing the power button. Then press Home button. If it doesn't bring the passcode screen, then press Home and Power button (at top right) until it brings the Apple logo. Release the buttons when you see Apple logo and then it will take you to passcode screen (press Home once or twice if asked or hold it to bring the passcode screen).
In the passcode screen, tap the first number and then double tap it to enter the first number and do repeat these until you enter all numbers of passcode. After entering all numbers of passcode, your iPad will unlock.
Then tap and double tap Settings, tap and double tap General, tap and double tap Accessibility, tap and double tap Voice Over and double tap on On/Off switch of Voice over to turn it off. To scroll, you have to swipe with three fingers.
Please let me know if that didn't work, so we can turn it of using different way
