Nine. That is the number of “uhs” that former President Barack Obama uttered in a period of two minutes during a 2012 presidential debate. Other Obama “uh” counters, such as University of Pennsylvania linguist Mark Liberman, clocked him as using “uhs” and “ums” – hesitation markers known as “filled pauses” in linguistspeak – roughly every 19 words during one interview.
By comparison, former President Donald Trump rarely uses them at all – as infrequently as once every 117 words.
