Title
Tomatis looked at the role of the leading ear in stuttering. This was from his finding that when he masked the leading ear some people with normal phonation they actually started to stutter. This result was not found in all subjects however. He started with the premise the "It was the right ear that controlled speech and stuttering was bound up with the loss of this controlling ear. This lead him to theories of laterality and control of listening that was relevant to stutters but applicable to many other listening disorders. At the same time he became aware of research being done in the United States at Georgetown University by John Lee and John Black. They found by delaying the feedback that someone received from their own voice, by speaking into a microphone, taping the voice, and delaying the feedback, they would elicit stuttering and that this stuttering occurred when the delay reached a specific threshold. Tomatis duplicated this experiment by using a long tube, making holes that corresponded to a one tenth of a second delay. Lee and Black had found that articulation difficulties occurred between one-tenth and two-tenth of a second. Tomatis found very similar results. He postulated that poor lateralization in contrast with good lateralization, introduces an element of delay caused by an extra step in the transfer of information
