Lipreading Deaf here.
I tried to lipread the Inauguration, and where it was successful I did read the same nonsense, but often it wasn't possible because they weren't looking at the camera or the microphone was in the way.
The Seagulls, however, the only thing I could read was amm-amm-ammmmm-am-am-aaaammm. Nothing else. Of course, the doll has very simple mouth mechanics.
