Suitability of Dysphonia Measurements for Telemonitoring of Parkinson's Disease
TL;DR: A new measure of dysphonia, pitch period entropy (PPE), is introduced, which is robust to many uncontrollable confounding effects including noisy acoustic environments and normal, healthy variations in voice frequency, and is well suited to telemonitoring applications.
Journal ArticleDOI
Novel Speech Signal Processing Algorithms for High-Accuracy Classification of Parkinson's Disease
TL;DR: It is found that some of the recently proposed dysphonia measures complement existing algorithms in maximizing the ability of the classifiers to discriminate healthy controls from PD subjects, and are seen as an important step toward noninvasive diagnostic decision support in PD.
Journal ArticleDOI
Accurate Telemonitoring of Parkinson's Disease Progression by Noninvasive Speech Tests
TL;DR: In this paper, the authors demonstrate rapid, remote replication of UPDRS assessment with clinically useful accuracy (about 7.5 points difference from the clinicians' estimates), using only simple, self-administered and noninvasive speech tests.
Journal ArticleDOI
Review: occupational risks for voice problems.
TL;DR: In this article, a review of the literature regarding the functional consequences of voice problems and occupational risk factors for them is provided, and the salient points are as follows: According to conservative estimates, approximately 28000000 workers in the US experience daily voice problems.

TL;DR: In this article, the long-term effects of the Lee Silverman voice treatment (LSVT) were assessed in patients with Parkinson's disease, using acoustic analyses of voice loudness and inflection in voice fundamental frequency (measured in terms of semitone standard deviation, or STSD).
