Voice therapy is the cornerstone of treatment for patients with voice disorders. The therapeutic role of the speech pathologist is important in patients with functional and organic voice disorders. Voice rest and various other treatment options, techniques, and applications for voices disorders are examined in this article.
Sixty subjects between the ages of 21 and 48 months were placed into groups based on mean length of utterance (MLU) and chronological age (CA) to test Stampe's hypothesis about the development of phonological processes. The subjects were given the Phonological Process Analysis (Weiner, 1979), and a proportion score for each of sixteen phonological processes was derived for each subject. The use of the various phonological processes across MLU groups and age groups was analyzed by multiple regression correlation, three-way ANOVA, and Tukey's HSD tests. MLU was found to be the best classification for the subjects for describing the phonological processes. The results and discussions present MLU-referenced guidelines regarding the emergence, duration, elimination, and universality of the sixteen phonological processes.
Spontaneous speech samples were elicited from eight mentally retarded children. Examples of consonant assimilation and reduplication found in their speech samples were separately analyzed to examine how these phonological processes function in the phonologies of retarded children. Results showed wide individual variability in subjects' use of consonant assimilation. Reduplication functioned to provide a method by which the subjects whose word productions were primarily monosyllabic could produce multisyllabic targets and/or to provide a method by which the subjects could produce multisyllabic words that had one syllable containing target consonants of consonant clusters absent from their phonetic repertoires.
