Purpose: Adequate velopharyngeal control is essential for speech, but may be impaired in Parkinson's disease (PD). Bilateral subthalamic nucleus deep brain stimulation (STN DBS) improves limb function in PD, but the effects on velopharyngeal control remain unknown. We tested whether STN DBS would change aerodynamic measures of velopharyngeal…

The study examined durations of phrases, words, and phones for nine apraxic and five normal adult speakers during normal and fast speaking conditions. Although normal speakers decreased the duration of words during the fast rate condition, there was no evidence that apraxic speakers changed their speaking rates between the conditions. (Author/DB)

Conversational speech of five children who stutter was recorded and then portions manipulated to modify interval duration and vowel duration. Results indicated that both interval and vowel durations moderately affected listeners' perception of stuttering. Generally, repetitions with short vowel and interval durations were judged as more…

This study compared the ratings of 19 adolescents when listening to recordings of the speech of eight children with cerebral palsy and eight normal-speaking children. For all 22 adjective pairs, the normal speakers were rated significantly more positively. (Author/DB)

This study compared duration characteristics of single repetitions of single-syllable words in the speech of 15 preschool children near the onset of stuttering to those of 18 nonstuttering children. There appeared to be a tendency for repetitions of very early stutterers to be faster than repetitions of nonstuttering children. (Author/DB)

Discussion of how functional neuroimaging has been applied to the study of speech production first reviews neuroimaging methods and limitations, then describes two approaches to study of the relevant speech areas: comparison across different language production tasks and comparison of effects of different stimuli within a single task. Examples…

This study correlated measures of nasalance computed by the Nasometer with listener judgments of nasality of speech passages spoken by 25 children with craniofacial disorders. Results showed a significant correlation between nasalance and nasality only when nasal consonants were not included in the passage spoken. (Author/DB)

Features associated with the production of linguistic prosody were investigated in seven young speech-disordered children and seven young children with age-appropriate speech abilities. The primary differences between groups were in time characteristics of imitated responses. Results are discussed in terms of physiologic and/or linguistic…

Ten adults with dysarthria of various etiologies, type, and severity were compared to age-matched and gender-matched nondysarthric speakers on 40 short sentences. Results indicated reduced intonation values for the dysarthric group and varying rates as a function of subject group and sentence type. Results suggest that dysarthria is a deficit in…

This study compared pragmatic skills of 5 children (ages 4-6) with specific language impairments (SLI) and their younger siblings matched for mean length of utterance. Analysis of communicative acts on three levels (social interchange, speech act, and conversational) indicated comparable performance within sibling pairs, but SLI children…

This study examined the speech of 54 young Spanish-speaking (Puerto Rican dialect) children with phonological disorders. It described the mean percentage-of-occurrence and standard deviation of phonological processes and the number and type of nontargeted process errors. Specific patterns characterizing the speech of these children were…

Systems for classifying speakers' communicative intents are typically limited in scope, in applicability across the full developmental range of language abilities and disabilities, and in their theoretical foundations. Criteria for an adequate system for analyzing communicative intents are discussed, and a system is proposed which meets those…
