This study, involving an adolescent and adult male with stuttering problems, evaluated modification of the frequency of electroglottograph-measured phonation intervals on stuttering and speech naturalness. Both subjects demonstrated that stuttering could be controlled by modifying the frequency of phonation intervals within short duration ranges,…

Three studies of phonological knowledge and generalization were conducted with six functionally misarticulating children, aged 3-4. Results indicated that productive phonological knowledge of the sound system influenced the amount of generalization learning. The extent of generalization learning was associated with the point on the knowledge…

This article addresses the rationale for and issues related to the use of speech appliances, especially a removable speech appliance that positions the tongue to produce the correct /r/ phoneme. Research results suggest that this appliance was successful with a large group of clients. (Author/DB)

Glossometry, a method of providing visual feedback of tongue positions, was used to teach four vowel sounds to six profoundly hearing-impaired children. After 15 to 20 50-minute training sessions, all subjects showed greater diversification of tongue postures for the vowels. Listener identifications were also generally better after therapy.…

This response to commentaries on EC 604 058 attempts to update and clarify views on the application of principles of assessment and intervention in phonological disorders in children. The lack of empirical demonstration that this approach is more effective and efficient than existing procedures is noted. (Author/DB)

Five profoundly hearing-impaired children were taught to speak seven consonant sounds using palatometry which allows learners to see tongue-to-palate contact patterns used in sound production. Results demonstrated that visual articulatory modeling and feedback of linguapalatal contact patterns is an effective means of teaching consonants and…

This response to Fey (EC 604 058) presents arguments and examples in support of using concepts of phonological processes and constructs in assessing and treating phonological disorders in children. The paper disagrees with Fey's contention that using the term "process" for "rule" leads to confusion. (Author/DB)

This study investigated the effectiveness of articulation training (daily sessions for 8 weeks) on the production of phonemes by 12 hearing impaired children (ages 5-10). Results suggest that phonemes with an intermediate error rate (trained at a phonological level) are easier to train than phonemes with a high error rate (trained at a phonetic…

Seven children with phonological disorders were analyzed for imperceptible acoustic distinctions for seemingly homophonous word pairs, and treatment was applied. Results indicate that productive knowledge of sounds and contrasts facilitates rapid learning of those sounds in treatment, and presence of an acoustic distinction for a contrast does not…

This response to Fey (EC 604 058) discusses the use of the term "phonological" to describe disordered speech patterns and suggests that phonological disorders include both phonetic and phonemic error types. Describing errors as either phonetic or phonemic is seen to lead to differential treatment procedures. (Author/DB)

Two studies, one within subjects and the other across subjects, evaluated the efficacy of teaching sounds in developmental sequence to nine young children (ages three to five). Treatment of later-acquired phonemes led to systemwide changes in untreated sound classes, whereas treatment of early-acquired phonemes did not. Findings suggest…

Two preschool children with phonological disorders were administered a linguistically based treatment program that utilized minimal pair words. Only when motoric components (models and phonetic placement cues) were added did both subjects successfully pass through all treatment steps, though neither subject generalized trained sounds to treated…

This study evaluated whether variations in the structure of minimal versus maximal opposition treatments would result in empirical differences in phonological learning with three four-year-old boys who excluded at least six sounds from their phonetic and phonemic inventories. Results indicated that treatment of maximal oppositions led to greater…

Twelve preschool children with phonological process errors were provided speech therapy either by a clinician or by both a clinician and a parent with the SpeechViewer system. Both groups improved significantly and did not differ significantly from each other in degree of change. (DB)

Ethnographic techniques were applied to a post hoc examination of children's incidental behaviors during a metalinguistic intervention procedure--behaviors ignored in the original experimental design. The reflective and qualitative nature of ethnography was used to account for the 12 phonologically impaired 4-year-olds' varied perceptions of…
