Here is the latest EVP that I caught. This was in June 2012 at a nursing home in Wi. Right at one second you can hear a whisper, maybe four words or syllables. In the background you can hear the 5 o'clock siren going off and after the whisper you can hear my daughter and I talking in the distance.
I'd consider this a Class C Evp. You can hear a whisper, but not make out what it's saying.
Here are some of the pictures we were looking at when we caught this evp. We found these stashed away up in the attic.
