By the development of this project we in no way suggest that therapy clinics are harmful or not necessary for people with speech difficulties. Rather the project encourages the concept of speech therapy from which many people even in the twenty first century shy away from. The system in its current state requires that the patient seek the help of an actual therapist for an initial evaluation pin pointing the vulnerable areas and the problems that need to be addressed.

    King was the leader of the civil rights movement in the United States during the 1950 and 1960. His nonviolent approach to social reform and political activism, characterized by mass marches and large gatherings designed to demonstrate both the widespread acceptance of the tenets of civil rights and the barbarism of those who opposed them, contrasted with the confrontational methods espoused by Malcolm X and the Nation of Islam. King's Letter from Birmingham City Jail (1963) and the 1963 speech in which he declared "I Have a Dream" are considered the written landmarks of the movement. Today they are counted among history's great statements of human right. King was born in Atlanta, Georgia, and was raised in a middle-class family.

    Albeit all different, most have one thing in common, echolalia. As a student of the masters program I hope to research ways I can better understand the reason behind it and what intervention methods are best. My goal in research is to support my clients in achieving a more spontaneous and intentional way of communication.
