...Ramesh Kaipa; Natalie McLain; Roha Mariam Kaipa Introduction: The purpose of the current study was to evaluate speech intelligibility and speech rate in individuals with Parkinson’s disease using altered auditory feedback (AAF) in comparison to age-matched healthy controls. Based on prior research...

...Tatiana Romero Arias; Inés Redondo Cortés; Adrián Pérez del Olmo Introduction: Previous research on voice in Parkinson’s disease (PD) has consistently demonstrated alterations in acoustic parameters, including fundamental frequency (F0), maximum phonation time, Shimmer, and Jitter. However...

... elicited by picture description can be used in the assessment of intelligibility in speakers with Parkinson’s disease. Methods: Speech samples from eleven speakers with Parkinson’s disease and six neurologically healthy persons were audio-recorded. Forty-two naive listeners completed transcriptions of self...

...Fredrik Karlsson; Lena Hartelius Objective: To investigate whether syllables produced in an oral diadochokinetic (DDK) task may be quantified so that persons with Parkinson’s disease (PD) perceived to have reduced articulatory precision when reading may be correctly identified using...

...Ghadah G. Alharbi; Michael P. Cannito; Eugene H. Buder; Shaheen N. Awan Purpose: This article examines cepstral/spectral analyses of sustained /α/ vowels produced by speakers with hypokinetic dysarthria secondary to idiopathic Parkinson’s disease (PD) before and after Lee Silverman Voice Treatment...

...Ellika Schalling; Kerstin Johansson; Lena Hartelius Background: Changes in communicative functions are common in Parkinson’s disease (PD), but there are only limited data provided by individuals with PD on how these changes are perceived, what their consequences are, and what type of intervention...

...Lena Hartelius Objective: The aim of this study was to investigate the incidence of developmental speech dysfluencies in individuals with Parkinson's disease (PD). Background: The possible relationship between PD and dysfluencies such as stuttering has engaged researchers for many years. However...

...L. Hartelius; P. Svantesson; A. Hedlund; B. Holmberg; D. Revesz; T. Thorlin The main characteristics of dysarthria in Parkinson’s disease (PD) are monotony of pitch and loudness, reduced stress, variable speech rate, imprecise consonants, and breathy and harsh voice. Earlier treatment studies have...

...L. Hartelius; P. Svensson A survey of approximately 460 patients with Parkinson’s disease (PD) or multiple sclerosis (MS) shows that speech and swallowing difficulties are very frequent within these groups. Seventy percent of the PD patients and 44% of the MS patients had experienced impairment...

...Bernadette R. Shea; Sakina S. Drummond; Steven Metzer; Kathleen M. Krueger Comprehensive speech examinations of 10 equally affected subjects with moderate, treated Parkinson’s disease were performed before and 4 weeks following initiation of treatment with selegiline (deprenyl), with other drug...

... dynamic analysis as a voice analysis tool for the effects of deep brain stimulation (DBS) and levodopa on patients with Parkinson’s disease (PD). Methods: In this study, the effects of DBS and levodopa treatment on patients with PD were measured using perturbation, nonlinear dynamic, and perceptual...

...Kate Bunton This study investigates the importance of fundamental frequency (F0) as a perceptual cue for identification of vowel targets produced by speakers with Parkinson’s disease (PD). It has been suggested in the literature that F0 is a redundant cue for vowel identification in highly...

...Kristin M. Rosen; Raymond D. Kent; Joseph R. Duffy This study examines intensity decay in the phonation of persons with Parkinson’s disease (PD). The decline in vocal intensity (determined by linear regression of the intensity envelope) was compared across the following tasks: vowel prolongation...

... dysarthria secondary to multiple sclerosis (MS) and Parkinson’s disease (PD). The results suggest that temporal measures are more useful than energy measures for distinguishing among dysarthria secondary to MS, dysarthria secondary to PD, and healthy controls. The results also highlight the value...

...Shimon Sapir; Lorraine O. Ramig; Patricia Hoyt; Stefanie Countryman; Christopher O’Brien; Margaret Hoehn Thirty-five individuals with idiopathic Parkinson’s disease were enrolled in speech treatment. Twenty-two were enrolled in a high-effort phonatory-respiratory treatment program (Lee Silverman...
