Automatic detection of Parkinson's disease in running speech spoken in three different languages
(Acoustical Society of America, 2016)
The aim of this study is the analysis of continuous speech signals of people with Parkinson's disease (PD) considering recordings in different languages (Spanish, German, and Czech). A method for the characterization of ...
Automated video-based assessment of facial bradykinesia in de-novo Parkinson’s disease
(Nature Publishing Group, 2022)
Even though hypomimia is a hallmark of Parkinson’s disease (PD), objective and easily interpretable tools to capture the disruption of spontaneous and deliberate facial movements are lacking. This study aimed to develop a ...
Articulatory undershoot of vowels in isolated REM sleep behavior disorder and early Parkinson's disease
(Nature Publishing Group, 2022)
Imprecise vowels represent a common deficit associated with hypokinetic dysarthria resulting from a reduced articulatory range of motion in Parkinson's disease (PD). It is not yet unknown whether the vowel articulation ...
Is Gait Dysfunction a Prominent Sign of Isolated Rapid Eye Movement Sleep Behavior Disorder?
(Wiley-Liss, 2022)
De Cock et al reporting a high classification accuracy of 95% to distinguish between isolated rapid eye movement sleep behavior disorder (iRBD), Parkinson's disease (PD), and healthy control subjects, using analysis of ...
Speech and gait abnormalities in motor subtypes of de-novo Parkinson's disease
(John Wiley & Sons, 2023)
AimTo investigate the presence and relationship of temporal speech and gait parameters in patients with postural instability/gait disorder (PIGD) and tremor-dominant (TD) motor subtypes of Parkinson's disease (PD). ...
Relationship between LTAS-based spectral moments and acoustic parameters of hypokinetic dysarthria in Parkinson's disease
(ISCA - International Speech Communication Association, 2023)
Although long-term averaged spectrum (LTAS) descriptors can detect the change in dysarthria of patients with Parkinson's disease (PD) due to subthalamic nucleus deep brain stimulation (STN-DBS), the relationship between ...
Which aspects of motor speech disorder are captured by Mel Frequency Cepstral Coefficients? Evidence from the change in STN-DBS conditions in Parkinson's disease
(ISCA - International Speech Communication Association, 2023)
One of the most popular speech parametrizations for dysarthria has been Mel Frequency Cepstral Coefficients (MFCCs). Although the MFCCs ability to capture vocal tract characteristics is known, the reflected dysarthria ...
Federated Learning for Secure Development of AI Models for Parkinson’s Disease Detection Using Speech from Different Languages
(ISCA - International Speech Communication Association, 2023)
Parkinson's disease (PD) is a neurological disorder impacting a person's speech. Among automatic PD assessment methods, deep learning models have gained particular interest. Recently, the community has explored cross-pathology ...
Glottal source analysis of voice deficits in basal ganglia dysfunction: evidence from de novo Parkinson's disease and Huntington's disease
(ISCA - International Speech Communication Association, 2023)
Dysphonia is a common speech disruption in people with Parkinson's (PD) and Huntington's (HD). Though the glottal source analysis (GSS) yielded promising results in PD, no study analyzed utility of the GSS in HD. In addition, ...
Comparison of acoustic measures of dysphonia in Parkinson's disease and Huntington's disease: Effect of sex and speaking task
(ISCA - International Speech Communication Association, 2023)
This study investigated whether voice quality is differentially affected in two distinct basal ganglia disorders causing hypokinetic and hyperkinetic dysarthria, including effects of gender and speaking task. The sustained ...
