Strange voice

       Last night, as I was sitting at the computer with both of my dogs at my side, I distinctly heard my name called. The interesting thing is so did both of my dogs who immediately got up and ran toward the kitchen. I followed, my wife was working on a craft project on the kitchen table. I asked what she wanted. She said she hadn't called me. I said the dogs both reacted to it. She replied that she absolutely had not said anything for quite some time. Even the kitchen TV was not on. This is not common, but these sounds do happen on occasion. But this time there was no mistake that the dogs heard it as well.
