TL;DR: The discrepancy between the production and recognition of prosodic features does not support the suggestion that dysprosody in Parkinson's disease is necessarily a disorder of processing emotional information that could be misinterpreted as a dysarthria.
Abstract: Prosodic features in the speech production of 21 patients with idiopathic Parkinson's disease were tested. The appreciation of vocal and facial expression was also examined in the same patients. Significant intergroup differences were found in the prosody production tasks but, in contrast to previous results, not in the receptive tasks on the recognition and appreciation of prosody and of facial expression. The discrepancy between the production and recognition of prosodic features does not support the suggestion that dysprosody in Parkinson's disease is necessarily a disorder of processing emotional information that could be misinterpreted as a dysarthria.

TL;DR: An overview of the ASR process is provided and the functioning of different types of ASR systems with dysarthria are discussed, as well as methods to assess the appropriateness of a selected system.
Abstract: The use of speech as a means of access can be a very powerful tool for individuals with motor disabilities. Knowledge of how automatic speech recognition (ASR) can function with dysarthric speech is important when selecting a system because dysarthria often accompanies other motor disorders. This paper provides an overview of the ASR process and discusses the functioning of different types of ASR systems with dysarthric speech. Methods to assess the appropriateness of a selected system are also described.

TL;DR: Telerehabilitation was feasible and effective in delivering the LSVT to people with PD and disordered speech.
Abstract: Summary The Lee Silverman Voice Treatment (LSVT) has been shown to be highly effective in treating the speech disorder in Parkinson's Disease (PD). However, patient access to this treatment remains limited in Australia, due to availability of speech pathologists, patient mobility and distance issues. We have investigated the feasibility and effectiveness of an Internet-based telerehabilitation application (eREHAB) for the delivery of the LSVT to persons with PD and disordered speech. Ten participants with PD and dysarthria were treated online with the LSVT for a total of 16 sessions. There were significant improvements in sound pressure levels for vowel prolongation, reading and conversational monologue (Po0.01), pitch range (Po0.05) and in perceptual features of pitch and loudness variability, loudness level (Po0.01) and breathiness (Po0.05). A participant satisfaction questionnaire indicated that 70% of participants expressed overall satisfaction with the online treatment. Telerehabilitation was feasible and effective in delivering the LSVT to people with PD.

TL;DR: The data suggest that speech deficits are chronic if not permanent sequelae of TCM, and survivors who had TCM showed more speech deficits than controls or survivors without TCM.
Abstract: Following cerebellar tumor resection, some patients develop transient cerebellar mutism (TCM). Although the mutism resolves, it is not known whether there are long-term motor speech deficits in patients with TCM that are in excess of those in individuals with cerebellar tumors who had not developed postoperative TCM. Long-term survivors of cerebellar tumors resected in childhood who developed TCM were matched to survivors without TCM and to controls. Speech samples were formally analyzed by two speech pathologists. Tumor survivors who had TCM had significantly more ataxic dysarthric speech and slower speech than either those without TCM or controls and were more dysfluent than controls. Tumor survivors without TCM did not differ from controls on ataxic dysarthria or speech rate. Survivors who had TCM showed more speech deficits than controls or survivors without TCM. The data suggest that speech deficits are chronic if not permanent sequelae of TCM.

TL;DR: The finding of a mixed dysarthria with a combination of spastic, hypokinetic, and ataxic components might assist in diagnosis and is consistent with the widespread neuropathologic changes found in PSP.
Abstract: We used oral motor examinations and quantitative perceptual speech analysis to study deviant speech dimensions in 44 patients with progressive supranuclear palsy (PSP). All patients had dysarthria with variable degrees of spasticity, hypokinesia, and ataxia; 28 patients had all three of these components, and 16 patients had only two components. Twenty-two patients (50%) had predominantly spastic components, 15 (34%) had predominantly hypokinetic components, six (14%) had predominantly ataxic components, and in one (2%) the spastic, hypokinetic, and ataxic components were equal. Stuttering occurred in nine patients (20%) and palilalia in five (11%). The finding of a mixed dysarthria with a combination of spastic, hypokinetic, and ataxic components might assist in diagnosis and is consistent with the widespread neuropathologic changes found in PSP.
