Stuttering is a condition that affects the rhythm or flow of speech. The individual who stutters knows exactly what they want to say, but at that very second they cannot get the words out in the way they would like. Stuttering is a motor speech disorder, and not a physical or emotional / psychological disorder. Stutters can consist of repetitions (e.g. m-m- mummy), prolongations (e.g. hoooowwww are you?), fillers (adding in an extra word as a compensatory strategy e.g. um) and blocks (when the sounds sound like they are getting stuck coming out).
