Background: Imprecise articulation has a negative impact on speech intelligibility. Therefore, treatment of articulation is clinically relevant in patients with dysarthria. In order to be effective and according to the principles of motor learning, articulation therapy needs to be intensive, well organized, with adequate feedback and requires…

PURPOSE: To determine empirically which of three frequently observed rules in children with phonological disorders contributes most to difficulties in speaker intelligibility. METHOD: To evaluate the relative effects on intelligibility of deletion of final consonants (DFC), stopping of fricatives and affricates (SFA), and fronting of velars (FV),…

This study examined effects of manipulating lung volume on phonatory and articulatory kinematic behavior during sentence production in ten healthy adults. Significant differences at different lung volume levels were found for sound pressure level, fundamental frequency, semitone standard deviation, and upper and lower lip displacements and peak…

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,…

This study had a two-fold purpose. It was concerned both with the effect of programed articulation therapy on Spanish-speaking subjects and with the role that distinctive features play on the phonological rules that affect articulation of three English phonemes. Fourteen adult Spanish-speaking subjects were involved and each demonstrated a…

Drawing in aphasia therapy has been used predominately as a substitution for speech or to augment communication when other modalities are non-functional. The value of drawing as a route for facilitating verbal expression has not been a focus of prior research. We compared the usefulness of drawing and writing as compensatory strategies for…

The effects of treatment on errors in consonant clusters and in ambisyllabic consonants were investigated in two adults with histories of developmental phonological problems. Results indicated that treatment, consisting of a sound-referenced rebus approach, affected change in production of trained words as well as generalization to untrained words…

First and second formant frequencies of the vowels /a/, /i/, and /u/ were measured to determine the phonological space in the speech of 30 Kannada-speaking hearing-impaired individuals in India. Compared to controls, subjects' phonological space was found to be reduced, primarily due to the lowering of the second formant of the vowel /i/.…

A semantic-based treatment was used initially to train naming of nouns in four adults with aphasia. Treatment responses and error patterns indicated treatment resulted in improved naming of both trained and untrained items for two participants. Two other participants showed improved naming only after phonological information was added. Results…

The present paper comprises an overview of techniques using ultrasound in speech (re)habilitation. Ultrasound treatment techniques have been developed for English lingual stops, vowels, sibilants, and liquids. These techniques come from a series of small "n" studies with adolescents and adults with severe hearing impairment, residual…
