“…A decrease in F 0 range during tasks was also reported by other investigators (Flint, Black, Campbell-Taylor, Gailey, & Levinton, 1992;Goberman, Coelho, & Robb, 2005;Metter & Hanson, 1986). Acoustic investigations of statements and questions produced by normal speakers and PD patients also demonstrated decreased F 0 changes marking the differences between the declarative and interrogative modes (Le Dorze, Ouellet, & Ryalls, 1994;Le Dorze, Ryalls, Brassard, Boulanger, & Ratte, 1988;Torp & Hammen, 2000). More recently, in an acoustic investigation of PD speech and control speech in linguistic and emotional context, F 0 differed between the two speaker groups for contrastive stress and emotional prosody production (Cheang & Pell, 2007).…”

“…Previous research has shown, in fact, that speakers with PD are impaired in specific aspects of intonation, such as the use of pitch patterns to mark contrastive stress and to indicate the sentence mode (Blonder, Gur, & Gur, 1989; Cheang & Pell, 2007; LeDorze, Ryalls, Brassard, Boulanger, & Ratté, 1998). Deficits in other areas, such as the strength and placement of focus markers and the production of phonemic stress patterns, appear to be more variable (Cheang & Pell, 2007; Darkins, Fromkin, & Benson, 1988; Hertrich & Ackermann, 1993; Penner, Miller, Hertrich, Ackermann, & Schumm, 2001).…”

Purpose This study examined the effect of Parkinson’s disease (PD) on the intonational marking of final and nonfinal syntactic boundaries and investigated whether the effect of PD on intonation was sex-specific. Method Eight women and 8 men with PD and 16 age- and sex-matched control participants read a passage at comfortable pitch, rate, and loudness. Nuclear tones from final and nonfinal syntactic boundaries in clauses and lists were extracted. Measures of F0 were made on each tone contour. Results Individuals with PD demonstrated impaired differentiation of syntactic boundary finality/nonfinality with contour direction. They produced a lower proportion of falling contours in final boundaries and a higher proportion of falling contours in nonfinal boundaries than control participants. While not mediated by syntax, the effect of PD on F0 standard deviation (F0 SD) and pitch range (PRST) was sex-specific. Women with PD produced greater F0 SD and PRST than men with PD and women without PD. Men with PD produced lower PRST than men without PD. Conclusions Impaired intonational marking of syntactic boundaries likely contributes to dysprosody and reduced communicative effectiveness in PD. The effect of PD on intonation was sex-specific. The results were not fully explained by PD-related motor execution impairments.

Clinical measures of dysarthria in Friedreich Ataxia

Dysarthria in Friedreich Ataxia (FA) is difficult to quantify. This study evaluated a series of performance measures for speech in 22 patients with genetically confirmed FA and 16 age-matched controls. Tests included the PATA examination, the PATAKA examination, the Oral Motor component of the Boston Aphasia examination, the Boston Cookie Theft description task, and the Assessment of Intelligibility of Dysarthric Speech. All measures, except the Cookie theft description task, demonstrated significantly lower scores for patients with FA when compared with controls and correlated with measures of disease progression. Thus, four of five measures capture speech dysfunction in FA and may provide feasible, inexpensive, quantitative testing for therapeutic monitoring in FA. Movement Disorder SocietyKey words: ataxia; sensory neuron; dysarthria; balance; clinical trial Friedreich ataxia (FA), an autosomal recessive neurodegenerative disorder, is characterized by ataxia, dysarthria, sensory loss, diabetes, and cardiomyopathy. 3 Scores from each measure are predicted by age and triplet repeat length in linear regression models, strengthening their link with the progressive nature of FA. However, no continuous measure of speech dysfunction is at present adequate for inclusion in such a composite measure. It is important to develop such a measure for assessment of laterstage patients because such patients frequently are too severely impaired to be assessed with most measures of arm and leg function.Although dysarthria is pervasive in FA, the exact neurologic components have been less well defined.4-9 Most speech dysfunction in FA reflects articulation deficits and is frequently classed with apraxic speech in that no true aphasia is present. Diagnostically, repetition of syllables (i.e., PATA), prolonged vowels, classification of changes in intonation, and rate of speech are traditionally used for characterization of ataxic speech. However, patient-related dysfunction may be more closely related to communicative ability and better measured by tests of intelligibility. 10,11 Previous studies show that PATA repetition does not correlate well with disease severity, suggesting that further measures need to be developed. In this work, we evaluated a series of performance measures for speech assessment in patients with FA to assess their reliability, ability to differentiate speech function in patients with FA from controls and correlation with disease progression. PATIENTS AND METHODS SubjectsPatients were recruited from the Children's Hospital of Philadelphia. The institutional review board approved all protocols. Control subjects had no medical history of dysarthria and were category matched by age with patients. Tests were administered by a research techni- In the AIDS, a standardized battery of speech samples was evaluated for intelligibility. In the first part, the subject pronounced 50 words selected from a standardized collection. To ensure consistency for all ages and reading levels, the examiner stated the wor...
