“…Also, swallowing was preserved even in most severe dysarthria cases by contrast to PSP. The absence of ataxic and nasal components distinguished Ephedrone dysarthia from the speech in MSA [23] Ephedrone induced dysarthria has perceptual similarity with post STN-DBS speech in PD patients. Astrom et al (2010) investigated the spread of the electrical current in post bilateral STN-DBS patients and found that patients with bilaterally medially placed electrodes (in the pallidothalamic tract) had more severely affected speech [24].…”

“…Recent research has revealed that men are more likely than women to lose their voice loudness and the quality of speech. They also take more pauses while speaking [ 32 ] and display disturbed prosody [ 33 , 34 ]. Evaluation of the efficiency of the larynx in men and women showed that women display a higher incidence of phonation disorders, glottis insufficiency and frequent laryngeal tremor.…”

BackgroundEvaluation of speech disorders in PD taking into account sociodemographic conditions is not frequent. This paper aims to establish correlations between articulation disorders in PD patients and factors such as the patients’ sex, age, education and residence.MethodsThe study included 92 patients with idiopathic PD diagnosed by means of multiple neurological examinations, biochemical tests, MRI and CT scanning carried out in accordance with the United Kingdom Parkinson’s Disease Society Brain Bank (UKPDSBB) criteria. A speech and language test involved the assessment of the mobility of the speech organs as well as the reflexes inside the oral cavity. Frenchay Dysarthria Assessment was applied for an objective evaluation of dysarthria.ResultsThe study revealed the existence of significant relationship between the functionality of articulators in PD patients and their education and residence. Big city dwellers demonstrated lower incidence of disorders within speech organs, particularly those affecting mobility of the soft palate while eating. Disorders of moderate intensity were more frequently found in subjects living in villages. Subjects with a university education displayed better position of the lips at rest and better performance of both lips and the mandible while speaking.ConclusionsAbnormal functioning of the articulatory organs was observed more frequently in PD patients residing in rural areas than in those inhabiting urban areas. As for education, our cohort university graduates displayed a better position of the lips at rest and better performance of the lips and jaw during speaking than those with secondary and vocational education.

“…• The intraword pause ratio measured as the ratio between the total pause time within polysllabic words and the total pause time [5] [6]. We define the polysllabic words' pauses as silences between 10ms and 120ms.…”

Parkinsonism refers to Parkinsons disease (PD) and Atypical parkinsonian syndromes (APS). Speech disorder is a common and early symptom in Parkinsonism which makes speech analysis a very important research area for the purpose of early diagnosis. Most of research have however focused on discrimination between PD and healthy controls. Such research does not take into account the fact that PD and APS syndromes are very similar in early disease stages. The main problem that has to be addressed first is then differential diagnosis: discrimination between PD and APS and within APS. This paper is a continuation of an earlier pioneer work in differential diagnosis where we mostly address the machine learning problem due to the small amount of training data. We show that classical linear and generalized linear models can provide interpretable and robust classifiers in term of accuracy and generalization ability.
