It was the purpose of this research project to compare a combined program of speech and myofunctional therapy for correcting an anterior lisp with a traditional speech approach and a myofunctional only approach. The project sought to answer the following questions: 1) Which of the three methods will effect the greater change in articulatory patterns for the /s/ and /z/ phonemes? and 2) Will six weeks of intensive management cause any significant difference in a client's speech patterns?
