Can someone tell me what the relationship between Siri and Voice Over or any other Accessibility feature is? My friend just got her first iPhone a few days ago. Yesterday she accidentally turned on Voice Over when she triple clicked the home button instead of double clicking it for multitasking. She didn't know what was going on (I didn't either really) but I was able to turn off voice over and disabled the triple-click home button shortcut for it. Since then, Siri only half works. She is completely silent. You can ask her stuff and she will perform tasks but there is no voice or sound feedback. When I hold down the home button to bring up Siri the "ding" doesn't even play. I am not exactly sure what I turned off in Accessibility when I was disabling Voice Over but I'm guessing I turned off some other (probably obvious) setting that Siri needs enabled to provide voice feedback. I do not have a 4S so I can't fiddle with it myself, but I want to give some advice to my friend on how to fix it.
