Q: Can't disable voice-dialing anymore since upgrade to iOS 7.1

I need to be able to disable voice-dialling on my iPhone4. I keep accidentally calling random contacts while using voice commands to control music on my motorcycle bluetooth headset. If this isn't fixed in the next "upgrade", I will be forced to change to an android phone. NOT HAPPY

iOS 6 worked great on my phone. Wish I had never upgraded to iOS 7, let alone 7.1.
