I have finally figured out what the announcers in north texas do to sing-song so much. Maybe they are being taught this in college, perhaps they are being hired by someone that loves the sound. Nevertheless it annoys me. It reminds me of nursery care centers and puts me into action to switch over to CDs.
The female announcers on both kera and the classic one raise and lower, they alter their intonation often, and without emotional reason. You can also hear them gather their first breath then race out across the sentence. I have just now figured that they are humming as they start. I mean, they begin speaking using their nose rather than their lips and mouth. The sounds comes out for just a moment , from their nose, then they open their mouth for the remaining portion.
Texas hummers. What bummers.
