TL;DR: Impairment of speech articulation did not correlate with age at onset of disease, but was positively related with disease duration and higher scores in both groups.
Abstract: Speech disorders are common manifestations of Parkinson´s disease. Objective To compare speech articulation in patients according to age at onset of the disease. Methods Fifty patients was divided into two groups: Group I consisted of 30 patients with age at onset between 40 and 55 years; Group II consisted of 20 patients with age at onset after 65 years. All patients were evaluated based on the Unified Parkinson’s Disease Rating Scale scores, Hoehn and Yahr scale and speech evaluation by perceptual and acoustical analysis. Results There was no statistically significant difference between the two groups regarding neurological involvement and speech characteristics. Correlation analysis indicated differences in speech articulation in relation to staging and axial scores of rigidity and bradykinesia for middle and late-onset. Conclusions Impairment of speech articulation did not correlate with age at onset of disease, but was positively related with disease duration and higher scores in both groups.

TL;DR: This study evaluated the efficacy of SPEAK OUT!
Abstract: Background/aims Hypokinetic dysarthria in Parkinson disease (PD) hinders the ability to verbally communicate and interferes with activities of daily living. SPEAK OUT!® is a therapy program designed to improve functional communicative ability. In contrast to the Lee Silverman Voice Treatment program, SPEAK OUT!® promotes speaking with intent to effect loud speech. This study evaluated the efficacy of SPEAK OUT!® in persons with idiopathic PD in 3 domains: self-reported voice handicap, clinical ratings of dysarthria and prosody, and acoustic analysis of prosody. Participants and methods Pre-/post-therapy data included PD participants' scores on the Voice Handicap Index (VHI) and the Voice-Related Quality of Life (V-RQOL) questionnaire, audio recordings, perceptual evaluation scores, and demographic data, such as age, sex, handedness, diagnosis, and onset of PD. Results Participants achieved a statistically and clinically significant improvement in speech intensity, pitch range, normalized pairwise variability index for pitch, sustained vowel duration, reading intelligibility, and vocal quality after SPEAK OUT!® training, consistent with both of the self-report voice scores, i.e., the VHI and the V-RQOL, and with the perceptual speech evaluation scores. Longer PD duration was associated with lowered efficacy. Conclusions SPEAK OUT!® is effective and should be administered as early as possible after disease onset.

TL;DR: The aim of the current study was to relate the results of phonological and perceptual evaluations to phonetic performances to better understand the relationship between these three components for speech outcomes, and understand the observed intonation patterns in ataxic dysarthria as well as the compensatory mechanisms speakers may adopt to produce stress.

TL;DR: This paper investigated the intonation in the read speech of two males with hypokinetic dysarthria resulting from idiopathic Parkinson's disease and compared them with two age-matched male controls.
Abstract: This study investigates the intonation in the read speech of two males with hypokinetic dysarthria resulting from idiopathic Parkinson's disease and compares them with two age-matched male controls. The investigation was carried out within the autosegmental-metrical framework (AM), which analyzes intonational contours as a sequence of abstract, discrete pitch targets (high or low tones) and permits analysis on two levels: the intonational phonology and its phonetic realisation. Despite its potential for revealing patterns of disordered usage, the AM approach has seldom been deployed in the analysis of disordered speech, and has never been used to investigate the intonation patterns of people with Parkinson's disease.Results showed that there were no differences between the participants with parkinsonian dysarthria and the healthy controls in the inventory of pitch accents and boundary tones (i.e., the phonological elements of intonation). Both groups used the same range of pitch accent types and b...

TL;DR: As a group, the children with TBI demonstrated normal, or only minimally impaired laryngeal function, when compared with the control group, which contrasts with the significant larynGEal impairment noted in adults after TBI.
Abstract: Objective: To investigate laryngeal function and phonatory disturbance in children with traumatic brain injury (TBI), using both perceptual and instrumental techniques. Design and participants: The performance of 16 individuals with moderate to severe TBI acquired in childhood and 16 nonneurologicatly impaired control subjects was compared on a battery of perceptual (Frenchay Dysarthria Assessment, speech sample analysis) and instrumental (Aerophone II, laryngograph) assessments. Results and conclusions: As a group, the children with TBI demonstrated normal, or only minimally impaired laryngeal function, when compared with the control group, which contrasts with the significant laryngeal impairment noted in adults after TBI. Several reasons for the different findings in relation to laryngeal function in adults and children after TBI are postulated: (1) differing types of injury usually incurred by adults and children may result in a relatively decreased degree of neurologic impairment in these children, (2) differences in recovery potential between adults and children, and (3) the pediatric larynx is still developing, hence it may be better able to compensate for any impairment incurred.
