TL;DR: The speech paradigm successfully identified the neural circuit of speech production and will be useful for studying normal and disordered speech in fMRI.

TL;DR: A patient with recurrent major depression, parkinsonism, and pseudobulbar symptoms underwent a course of electroconvulsive therapy, and although his depression and parkinsonian symptoms markedly improved, his dysarthria worsened, resulting in cessation of further treatments.
Abstract: A patient with recurrent major depression, parkinsonism, and pseudobulbar symptoms underwent a course of electroconvulsive therapy. Although his depression and parkinsonian symptoms markedly improved, his dysarthria worsened, resulting in cessation of further treatments. Possible mechanisms are explored.

TL;DR: An original perceptual evaluation protocol applied to a limited set of decisions made by the automatic system, related to the presence of anomalies, highlighted the difficulty for a human, even expert, to apprehend and detect deviations at the word level in dysarthric speech.
Abstract: Perceptual evaluation is still the most common method in clinical practice for the diagnosis and monitoring of the condition progression of people suffering from dysarthria (or speech disorders more generally). Such evaluations are frequently described as non-trivial, subjective and highly time-consuming (depending on the evaluation level). Clinicians have, therefore, expressed their need for new objective evaluation tools more adapted to longitudinal studies or rehabilitation context. We proposed earlier an automatic approach for the anomaly detection at the phone level for dysarthric speech. The system behavior was studied and validated on different corpora and speech styles. Nonetheless, the lack of annotated French dysarthric speech corpora has limited our capacity to analyze some aspects of its behavior, and notably,its severity (more anomalies detected automatically compared with human expert). To overcome this limitation, we proposed an original perceptual evaluation protocol applied to a limited set of decisions made by the automatic system, related to the presence of anomalies. This evaluation was carried out by a jury of 29 non-naive individuals. In addition to interesting information related to the system behavior, the evaluation protocol highlighted the difficulty for a human, even expert, to apprehend and detect deviations at the word level in dysarthric speech.

TL;DR: It can be concluded that HIV infection results in speech impairments in the affected individuals, but this conclusion has to be generalized with caution since only 15 participants were involved in this study.
Abstract: Infection due to Human immunodeficiency virus (HIV) can cause damage to both the central and peripheral nervous systems and result in disorders of communication. Progressive decline in speech behaviours in HIV infected individuals have been documented in Western literature (Flower and Sooy, 1987). This study aims to create a database of speech impairments seen in individuals with HIV infection to reflect the need for assessment and management of communication skills. 15 males with HIV infection between the age ranges of 18 - 40 years were included in the study. The deviant speech characteristics was profiled on the parameters in Frenchay Dysarthria Assessment. 93.3% of the participants demonstrated speech impairments which ranged across the participants. Most affected were parameters of tongue and laryngeal functions followed by reflex, respiration, lip functions and intelligibility parameters. Jaw and soft palate functions were not affected in any of the participants. It can be concluded that HIV infection results in speech impairments in the affected individuals. But this conclusion has to be generalized with caution since only 15 participants were involved in this study. Further research considering the effects of medication, opportunistic infections and disease duration is suggested.

TL;DR: The aim of this study was to characterize the voice and the speech of patients with MSA, where hypokinetic, ataxic and spastic components were seen in each of the patients, although hypokeretic component predominated among the others.
Abstract: Multiple system atrophy (MSA) is characterized by parkinsonian, cerebellar and pyramidal features along with autonomic dysfunction in different combinations. Onset of dysarthria during the first year of the manifestation of a parkinsonian syndrome suggests the diagnosis of MSA. The aim of this study was to characterize the voice and the speech of patients with MSA. We studied five MSA patients with a mean age of 51.2 years. Each patient was submitted to a neurological and a specific speech and voice assessment. The latter consisted of the following: clinical interview, myofunctional examination, and perceptual speech evaluation. Speech and voice complaints occurred at an average time of 1.1 year after the onset of the motor symptomatology. All MSA patients had the mixed type of dysarthrophonia, where hypokinetic, ataxic and spastic components were seen in each of the patients, although hypokinetic component predominated among the others. Our findings are different from what is commonly seen in Parkinson's disease in which hypokinetic component is the only abnormal finding. We think that specific speech and voice assessment is important to establish the diagnosis and to choose the best management of MSA patients.
