Disfluency:
Based on previous research, psycholinguist Hans Rutger Bosker and his team already knew that people sprinkle their speech with so-called disfluencies, the um’s, ah’s, uh’s and pauses that we often unwittingly slip into conversation. They also knew that these disfluencies usually cropped up before someone said a word that wasn’t in their everyday vernacular.
