This book was released on 2015 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well established that individuals with Parkinson's disease (PD) exhibit differences in their ability to perform internally guided (IG) movements versus externally guided (EG) movements. The goal of this study was to evaluate the vocal parameters of utterances produced by ten speakers with Parkinson's disease in two contexts: covert conversation (an IG context) and sentence reading (an EG context). Analyses were centered on measures of dysfluency, speaking rate and pitch variation. Results revealed significant differences for two of the ten speakers between speaking conditions. Namely, these speakers spoke faster and more fluently in the EG condition. Findings partially align with those of the original study (Weir-Mayta, 2014) which found perceptually salient differences between IG and EG conditions for six of the ten speakers. Future research is needed to continue to explicate the effects of external cuing on motor speech performance in individuals with PD.

This book was released on 2016-11-11 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of speech of people with Parkinson's disease is an interesting and highly relevant topic that has attracted the research community during several years. The advances in digital signal processing and pattern recognition have motivated the research community to work on the development of computational tools to perform automatic analysis of speech. Most of the contributions on this topic are focused on sustained phonation of vowels and only consider recordings of one language. This thesis addresses two problems considering recordings of sustained phonations of vowels and continuous speech signals: (1) the automatic classification of Parkinson's patients vs. healthy speakers, and (2) the prediction of the neurological state of the patients according to the motor section of the Unified Parkinson's Disease Rating Scale (UPDRS). Recordings of three languages are considered: Spanish, German, and Czech. German and Czech data were provided by other researchers, and Spanish data were recorded in Medellin, Colombia, during the development of this work. Besides the classical approaches to assess pathological speech, a new method to model articulation deficits of Parkinson's patients is proposed. This new articulation modeling approach shows to be more accurate and robust than others to discriminate between Parkinson's patients and healthy speakers in the three considered languages.

This book was released on 1998 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was designed to examine the effect of four rate control procedures on speech rate in Parkinson's Disease (PD) and normal subjects. Utterance duration of a target phrase across fast and slow speaking conditions was measured during the following rate control procedures: magnitude production, delayed auditory feedback, computerized rhythmic pacing, and metronome pacing. The main findings were that PD subjects produced a faster rate of speech than normals during the slowest speech conditions of magnitude production, thereby underestimating the scaling of their speech at the slowest end of the continuum. In addition, it was found that PD subjects were more variable than normals during the slowest speech rate conditions of each rate control procedure. Furthermore, during the visuomotor speech task of the computerized rhythmic pacing procedure, PD subjects produced more variable speech rates. These results appear to be in general agreement with previous studies of speech rate in patients with PD.

This book was released on 2014 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well established that individuals with Parkinson's disease (PD) have difficulty performing skilled movement when forced to rely on internal cues versus responses guided by external stimuli. This discrepancy has been attributed to the dysfunctional basal ganglia lacking an adequate, internally generated model causing persons with PD to become overly reliant on external cues to guide skilled movement. The extent to which speech production aligns with theories of internal versus external cuing is not well understood. The purpose of this study was to examine the effect of an internally versus externally cued speech task on the understandability and naturalness of speakers with PD and a clinical comparison group of speakers with cerebellar disease (CD) as perceived by 10 experienced speech-language pathologists. A direct comparison was made between sentences extracted from a covertly recorded conversational sample (internally cued) and the reading of those same sentences by the speakers (externally cued). The listeners rated the speech samples using a visual analog scale for the perceptual dimensions of understandability and naturalness. Results suggest that experienced listeners perceived the speech of participants with PD as more natural and more understandable during the reading condition. The cerebellar group also demonstrated a difference between speaking conditions, but only for understandability. Thus, the percept of naturalness appeared to be sensitive to capturing the differences between speakers with Parkinson's disease and cerebellar disease.

This book was released on 2013 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study examined the effects of speaking mode (clear, habitual, slow speech) on speech production and speech perception of individuals with and without Parkinson's disease. In the speech production task there were 21 speakers who read the Farm passage in habitual, clear and slow speech modes. Acoustic analysis involving the assessment of the first and second formant frequencies was performed using vowel space areas, vowel dispersions, /i-alpha/ distances for both tense and lax vowels produced in each of the speaking conditions. Duration ratios of both the tense and lax vowels were also examined in each condition. Effects of the conditions on perception were investigated in two listening tasks. In the first task, 3 listeners heard a subset of speakers from the production portion. In a forced choice task the listeners then selected the vowel they preferred in a given speaking condition. In the second listening task, 10 listeners used a 7-point Likert rating scale to rate 4 sentences produced in each of the 3 conditions for the 21 speakers. Production results showed that vowel space areas were larger in the clear and slow conditions compared to habitual, with no statistically significant difference between clear and slow. Results from the first listening task showed a preference for vowels in clear speech mode, and the second showed that speakers were rated most intelligible in clear speech mode.

This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Parkinson's disease (PD) is a neurodegenerative syndrome that results in various movement abnormalities, including a resting tremor, bradykinesia (slow or reduced range of movement), rigidity due to increased muscle tone, a delay in the initiation of movements, and disturbances of postural reflexes. This can lead to secondary conditions such as depression, dementia, swallowing difficulties, and a speech disorder called hypokinetic dysarthria. The aim of this doctoral project is to find robust and "trackable" markers in hypokinetic dysarthria associated with PD across two-time points. These markers could indicate a change in PD motor symptoms. The original plan for this study was to take speech recordings of people with PD and age-matched controls, face to face in a recording studio, for acoustic analysis. However, with the onset of the COVID-19 pandemic, a change of plan was required. The move to online data collection presented several new challenges while also having a positive effect on participant numbers. This case study focuses on the data collection process used to collect speech data online from people with PD and a control group for the purpose of acoustic analysis. Issues encountered in collecting reliable speech data online are discussed, including the key factors of consideration such as audio quality, ease of the data collection process for participants, and the available methods to record speech data remotely. Finally, the application of this method of data collection in other linguistics studies and wider use in social sciences is outlined.

Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the role of loudness perception and selected auditory processes in 17 participants with hypophonia related to Parkinson's disease (PD) and 25 controls. For most of the five loudness perception tasks (magnitude estimation, imitation, speech-to-noise judgment, magnitude production, magnitude production in noise), the PD participants produced a significantly different pattern and used a more restricted range than the controls in their self-generated estimates of speech intensity and judgments of speech loudness. Results from two self-assessment questionnaires (CETI-M, M-SAPP) found that the PD participants perceived themselves as less effective communicators than controls. An audiometric evaluation suggested that the PD participants may have abnormalities related to higher admittance values, higher acoustic reflex thresholds and higher pure-tone thresholds for lower frequencies. These results suggest that individuals with PD may have a speech loudness perception deficit involving the abnormal perception of externally-generated and self-generated speech intensity stimuli.

This book was released on 2017-01-05 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have brought new insights to the understanding of Parkinson’s disease, impact of exercise and sound displays in rehabilitation and movement facilitation. There is growing evidence that auditory signals in the environment can provide a temporal template for movement and change the mode of motor control from intrinsic to extrinsic; habitual to goal-directed, enabling enhanced motor performance in patients. In addition, forced exercise rate studies show that exercising at the pace of healthy adults can have potential neuroprotective benefits for patients. Many research groups have explored the use of auditory cues (such as rhythmical auditory training) in improving gait and upper limb movement parameters. Cues are usually either intermittent (metronome) or continuous (dynamic sound displays). Similarly, dance based interventions suggest that patients benefit from additional sensory information (i.e. the temporal structure embedded in music and proprioceptive information from a dancing partner) that facilities movement. On the contrary, studies dedicated to auditory perception and motor timing report an impaired ability of patients to perceive and synchronise with complex rhythmical structures (i.e. causing an inability to play musical instruments). With the growth of modern technology and the increasing portability of hi-specification devices (such as smart phones), new research questions on the design of interventions are beginning to emerge as we strive for more efficient therapeutic approaches. In this Research Topic we wanted to bring together top scientists from the movement disorder, motor control and sound related studies along with therapists. That way, we can engage in cross-disciplinary and challenging scientific debate about future rehabilitation avenues and frontiers for Parkinson’s disease patients.
