Since the iOS 7 update, when I receive calls, the person on the other cannot hear me, although I can still hear them. Also, when I try to give Siri a command, Siri cannot hear me. Has anyone else had that problem too?

Once the alert is answered it wont pop up again. You have to go to: Settings -> Privacy -> Microphone Then check the state of your app.
I had this problem in the past (on iOS 6 so not sure whether this could be helpful to you). A cold reset fixed the issue with the microphone.
