a full investigation into the features extracted from voice signals of people with and without parkinson’s disease was performed. a total of 31 people with and without the disease participated in the data collection phase. their voice signals were recorded and processed. the relevant features were then extracted. a variety of feature selection methods have been utilized resulting in a good perf...

BACKGROUND Pure dysarthria (PD) and dysarthria-facial paresis syndrome (DFP) mainly result from lenticulostriate artery territory infarction. PD and DFP are rare clinical entities, often grouped without distinction. The purpose of this study was to examine clinical and radiographic differences between PD and DFP due to unilateral internal capsule and/or corona radiata infarction. METHODS Usin...

Significant changes in dysarthric speech can be achieved many years post-onset of traumatic brain injury (TBI). Individuals with TBI dysarthria frequently apply phonetic processes (PPs) that are viewed as speech errors. This study reports the results of two Examinations (E1, E2) of PPs and their influence on the speech intelligibility rate at 12 (E1) and 50 (E2) months post-coma in ML, a 26-yea...

A few patients with an affected CNS involving abnormalities in copper metabolism have been described that do not fit any known nosological entities such as Wilson's disease or Menkes' disease. Three sporadic patients (two men and one woman) were examined with involuntary movements and dysarthria associated with abnormal concentrations of serum copper, serum ceruloplasmin, and urinary copper exc...

PURPOSE This study examined the relationship between listener comprehension and intelligibility scores for speakers with mild, moderate, severe, and profound dysarthria. Relationships were examined across all speakers and their listeners when severity effects were statistically controlled, within severity groups, and within individual speakers with dysarthria. METHOD Speech samples were colle...

This critical review examines the effect of singing on speech characteristics of adults who have dysarthria. Study designs include: two case studies, a single system design with baseline reversal, a multiple case study experimental design, and an informational article. Overall, research suggests that singing may improve speech characteristics and intelligibility of adults with dysarthria. The c...

A 32 years female presented with gradually progressive dysarthria, dysphagia, oromandibular dystonia and mild generalized weakness. She had several episodes of acute psychotic behavior. She had abnormal saccadic eye movements, generalized hypertonia and exaggerated jerks in upper limbs. She was previously treated in a peripheral hospital for severe vomiting and diarrhea. MRI of brain revealed s...

It is essential to understand the voice characteristics in normal aging process accurately distinguish presbyphonia from neurological disorders. This study developed best ensemble-based machine learning classifier that could hypokinetic dysarthria using classification and regression tree (CART), random forest, gradient boosting algorithm (GBM), XGBoost compared prediction performance of models....

Case histories of two unrelated patients suffering from sensory ataxic neuropathy, dysarthria/dysphagia and external ophthalmoplegia (SANDO) are reported. Both patients showed compound heterozygosity for POLG1 gene mutations, and presented with symptom of the clinical characteristics of SANDO. A patient with a p.A467T and p.W748S, well-known mutations showed a progressive course with early onse...
