Stuttering is a fluency disorder which affects speech. It can begin during childhood, and sometimes may last throughout the course of life. Stuttering is characterized by disruptions in the production of speech sounds. Many people will have disruptions in their speech by repeating some words such as “um” or “uh”. These disruptions are not a problem, but once a person produces too many of them, they impede on communication and become a problem.The signs and symptoms of stuttering include repetitions of words or parts of words, and prolongations of speech sounds. People who stutter appear to be very tense causing the airflow to be completely stopped or blocked. Blocked airflow occurs when the mouth is positioned to say a word, for few seconds, but no sound is forthcoming. Interjections may also occur during stuttering where the child might say “um” for a long period of time to delay the start of a word that they typically get stuck on.
