I was listening to my iTunes music when I connected a USB card reader to my Mac and I was surprised a voice said a USB device connected and the same happened when I ejected/disconnected it. As far as I know Voice Over is off on my early 2012 Mac mini 10.8.4. When i turned on VO (Command+Option+F5) the voice was female, the voice I've been hearing is male. Is there a way to turn this voice off?
