The development of a universal speech facilitation program as an extension of the speech motor learning program and its application in an experimental alternating treatment study

Abstract

A universal speech facilitation program was developed based on the principles, methods and long-term goals of an existing program, the Speech Motor Learning Program (Van der Merwe, 1985). The development of such a program was indicated because, to date, no systematized intervention program with the aim of general speech facilitation has been attempted to overcome the tremendous challenges of the current rehabilitative scenario in South Africa (shortage of services, untrained staff in the community and multiple language barriers to name a few). The suitability of the SMLP as a starting point for the compilation of a Speech Facilitation Program is illustrated by its clinical success in treating a variety of speech disorders and secondly because it is firmly based on normal speech development and motor learning principles. Based on the SMLP, the SFP was developed and applied to two paired subjects who exhibited general speech and language delay, to determine if the speech facilitation program would facilitate and indeed enhance speech development in the Subjects. The clinical application of the SFP was conducted in an alternating treatment design study using speech facilitation and language treatment respectively. During the treatment phase of the study, probe tests, consisting of ten selected aspects of speech and language, were conducted to determine the effect of the two treatment approaches on these aspects. Three of the aspects showed improvement following treatment with the Speech Facilitation Program. Four aspects showed gradual development throughout the duration of the study, irrespective of the type of treatment and it could possibly be attributed to general development by the subjects as well as regular intervention. Three aspects showed no change during the study. The obtained results seemed to indicate that the SFP influenced speech development positively and that it could be developed into a valuable clinical tool for the treatment of certain speech disorders.
