Stuttering is characterized by disturbances in the fluency of the speech. It begins in childhood and usually people suffer from that throughout life. At starting the person is not aware of this problem. Stuttering is often accompanied by motor movements such as eye blinks, tics, tremors of the lips or face, jerking of the head, breathing movements, or fist clenching. It disrupts the proper communication by a person and mostly detected by listeners. Sometimes the features are not easily recognized by the listeners therefore diagnosing stuttering often requires the skill of certified speech-language pathologist (SLP).
