What is the “Poet Voice” signaling?

By comparing Poets and Talkers along these lines, the researchers were able to draw two overall conclusions. First, when compared to the Talkers, the poets tended to speak more slowly and stay within a narrower pitch range. Second, very few Talkers indulged in long pauses, but plenty of poets—33 percent—had no trouble leaving their listeners hanging for two seconds or more…

This is also, perhaps, why it can seem grating or detached: “In a more natural conversational intonation pattern, you vary your pitch for emphasis depending on how you feel about something,” says MacArthur. “In this style of poetry reading, those idiosyncrasies … get subordinated to this repetitive cadence. It doesn’t matter what you’re saying, you just say it in the same way.” Overall, the researchers write, “from this small sample, we would conclude that perhaps when some listeners hear poets read with one or more of these characteristics—slow pitch speed, slow pitch acceleration, narrow pitch range, low rhythmic complexity, and/or slow speaking rate—they hear Poet Voice.”
