Book Description
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.

Book Description
This book constitutes the revised and extended papers of the First Automatic Assessment of Parkinsonian Speech Workshop, AAPS 2019, held in Cambridge, Massachusetts, USA, in September 2019. The 6 full papers were thoroughly reviewed and selected from 15 submissions. They present recent research on the automatic assessment of parkinsonian speech from the point of view of such disciplines as machine learning, speech technology, phonetics, neurology, and speech therapy

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
The purpose of the current study was to determine the extent to which a clear speech instruction would modulate acoustic measures of intonation and speech timing in speakers with and without PD in reading and extemporaneous speech tasks. Speakers both read simple reading passages and responded to self-selected extemporaneous speech prompts. Participants first performed the reading and extemporaneous speech tasks in a habitual manner, and then a second time in a clearer than usual style following an instruction to "over-enunciate each word." The speech samples were parsed using a process specified by the Systemic Theory of Functional Linguistics and further analyzed acoustically for measures of intonation and speech timing. Results revealed that speakers with PD presented with overall less variation in fundamental frequency and slower falling and rising fundamental frequency contours than controls regardless of speaking style. Speakers with PD exhibited significantly less clarity-related reduction in articulation rate than controls for both speaking tasks. For the reading task, all speakers exhibited clarity-related reduction in articulation rate. For the extemporaneous task, only control speakers exhibited clarity-related changes in articulation rate and pause durations, whereas speakers with PD exhibited no change in articulation rate between the habitual and clear speech styles. These results may indicate that speakers with PD exhibited a less robust clear speech response than controls. Additionally, it is possible that the higher cognitive-linguistic load of the extemporaneous task interfered with the magnitude of the clear speech response. Together, the demands of generative language and clear speech production associated with the extemporaneous task may have reduced some of the clear speech benefits for speakers in the PD group.
