A few years ago, I was working on an intonation project with several people. As part of the research, we were annotating soundfiles for specific phenomena. One of the things we were annotating was the location of a the maximum f0, the point in a given region of speech where the pitch is highest. For the specific project we were doing, we were labelling this point with the symbol ^, also known as a caret. It came up along the way that in some examples, we also wanted to mark another point that was linked to the caret to indicate when the peak f0 formed more of a plateau in shape. It was decided that we should use p to indicate a plateau. In reviewing our decisions about our labelling scheme, one of the women on the project was stressing that while not every peak would have a plateau marker, every plateau should be marked also for the peak. My coworkers looked at me questioningly when I started to snicker at this review of our protocol.
“No Ps without carets,” I said, by way of explanation.
Here’s one last serving of vegetables for you:
Eat every carrot and pea on your plate.
