“…Contrary to previous studies (Canter, 1963;Fox & Ramig, 1997;Goberman et al, 2002;Skodda et al, 2011a;Tjaden et al, 2013;Walsh & Smith, 2011; but see Canter, 1963;Sadagopan & Huber, 2007;Tjaden & Wilding, 2004), mean SPL and mean F0 did not differ across groups in the current study. However, speakers with PD did produce less variation in sentence-level SPL compared with controls, as indexed by SPL standard deviation.…”

“…For example, relative to healthy controls, speakers with PD produce more centralized vowel space areas (VSAs; Liu, Tsao, & Kuhl, 2005;Tjaden, Lam, & Wilding, 2013;Turner, Tjaden, & Weismer, 1995;Weismer, Jeng, Laures, Kent, & Kent, 2001), less spectrally distinct consonants (Tjaden & Wilding, 2004), weakened or less precise stop closures (Ackermann & Ziegler, 1991), and shallower second formant (F2) slopes, indicating slowed changes in vocal tract adjustments (Kent & Adams, 1989;Kim, Kent, & Weismer, 2011;Walsh & Smith, 2011). At the suprasegmental level, speakers with PD tend to pause more often (Torp & Hammen, 2000; but see Goberman & Elmer, 2005), utilize an increased fundamental frequency (F0; Canter, 1963;Goberman, Coelho, & Robb, 2002), and exhibit decreased variability in F0 (Canter, 1963(Canter, , 1965Flint, Black, Campbell-Taylor, Gailey, & Levinton, 1992;Skodda, Visser, & Schlegel, 2011a). Some studies have also reported reduced sound pressure levels (SPLs; Fox & Ramig, 1997;Skodda, Visser, & Schlegel, 2011b;Tjaden et al, 2013;Walsh & Smith, 2011).…”

Purpose The authors investigated how different variants of clear speech affect segmental and suprasegmental acoustic measures of speech in speakers with Parkinson's disease and a healthy control group. Method A total of 14 participants with Parkinson's disease and 14 control participants served as speakers. Each speaker produced 18 different sentences selected from the Sentence Intelligibility Test (Yorkston & Beukelman, 1996). All speakers produced stimuli in 4 speaking conditions (habitual, clear, overenunciate, and hearing impaired). Segmental acoustic measures included vowel space area and first moment (M1) coefficient difference measures for consonant pairs. Second formant slope of diphthongs and measures of vowel and fricative durations were also obtained. Suprasegmental measures included fundamental frequency, sound pressure level, and articulation rate. Results For the majority of adjustments, all variants of clear speech instruction differed from the habitual condition. The overenunciate condition elicited the greatest magnitude of change for segmental measures (vowel space area, vowel durations) and the slowest articulation rates. The hearing impaired condition elicited the greatest fricative durations and suprasegmental adjustments (fundamental frequency, sound pressure level). Conclusions Findings have implications for a model of speech production for healthy speakers as well as for speakers with dysarthria. Findings also suggest that particular clear speech instructions may target distinct speech subsystems.

“…This research has analysed acoustically the voice of 27 males with PD and 27 without it, and it was found that measures of fundamental frequency (F0) and jitter showed a statistical difference between groups with higher values in the PD Group. The higher values of F0 in PD patients treated with dopaminergic drugs, when compared to the Control Group, are similar to those found in the literature [16][17][18][19] , which may be the rigidity result of the laryngeal and respiratory muscles 20 , besides the laryngopharyngeal tract hypomobility 19 . Therefore, stiffness and hypokinesia seem to be responsible for the increase in the F0 in men with PD 19 .…”

“…The perceptual evaluation parameter of asthenia, observed in PD, has been associated with two distinct mechanisms, which, however, are coincident in their clinical expression: respiratory support and limitation of adduction of the vocal folds 19 . The presence of weakness also appears in other studies 8 , while the strain parameter found in this research can be the result of a patient's compensation mechanism facing the frame stiffness, present in PD.…”

OBJECTIVE: To compare voice and life quality of male patients with idiopathic Parkinson's disease, with individuals without disease (Control Group). METHODS: A cross-sectional study that evaluated the voice of individuals with Parkinson's disease, the group was composed of 27 subjects, aged from 39 to 79 years-old (average 59.96). The Control Group was matched on sex and age. Participants underwent voice recording. Perceptual evaluation was made using GRBASI scale, which considers G as the overall degree of dysphonia, R as roughness, B as breathiness, A as asthenia, S as strain and I as instability. The acoustic parameters analyzed were: fundamental frequency, jitter, shimmer, and harmonic to noise ratio (NHR). For vocal self-perception analysis, we used the Voice Related Quality of Life protocol. RESULTS: Fundamental frequency and jitter presented higher values in the Parkinson's group. NHR values were higher in the Control Group. Perceptual analysis showed a deviation ranging. The vocal disorder self-perception demonstrated a worse impact on quality of life. CONCLUSIONS: Individuals with Parkinson's disease have an altered voice quality and a negative impact on quality of life.

“…The irregularity references of vocal fold vibration in PD can be explained by the rigidity and hypokinesia of the muscles involved in the speech 11 . In relation to the instability, it is known that the voice of individuals with PD is more altered [11][12][13]15 . In a study that correlated the perceptual evaluation and the contractile pattern of intrinsic muscles of the larynx, it was found vocal tremor, leading to instability.…”

OBJECTIVE: To compare the voice quality of women with idiopathic Parkinson's disease and those without it. METHODS: An evaluation was performed including 19 female patients diagnosed with idiopathic Parkinson's disease, with an average age of 66 years, and 27 women with an average of 67 years-old in the Control Group. The assessment was performed by computed acoustic analysis and perceptual evaluation. RESULTS: Parkinson's disease patients presented moderate rough and unstable voice quality. The parameters of grade, roughness, and instability had higher scores in Parkinson's disease patients with statistically significant differences. Acoustic measures of Jitter and period perturbation quotient (PPQ) significantly differ between groups. CONCLUSIONS: Parkinson's disease female individuals showed more vocal alterations compared to the Control Group, when both perceptual and acoustic evaluations were analyzed.
