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.
Book Synopsis Acoustic and Articulatory Kinematic Vowel Space in Parkinsonian Speech by : Marisa Lucarelli

Available in PDF, EPUB and Kindle. Book excerpt: This study compares acoustic and articulatory productions of Parkinsonian speakers to healthy controls, concentrating more specifically on how vowels are articulated in the presence of tremors and rigidity. Four subjects diagnosed with Parkinson's Disease and four healthy controls were recorded stating utterances comprised of six English vowels on a 3-D Electromagnetic Articulograph. Acoustic differences in vowel quality between the healthy and pathological speech were measured and analyzed by extracting the first and second formant frequencies from the acoustic signal. Similarly, differences in vowel articulation were studied by comparing the maximum displacement of the tongue between the two populations. Acoustic and articulatory vowel space areas were also calculated in a scatter plot. Statistical analysis comparing the acoustic and articulatory vowel space area, vowel production and formant frequencies show an overall decreased acoustic tense and lax vowel space area in those with Parkinson's disease with the exception for tense vowels in males. Parkinsonian speakers also had a higher variability of individual vowel productions, both acoustically and articulatorily while maintaining vowel identity and have more variability overall in the vowel productions related to the vertical axis.

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 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 2017-11-30 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA) came into being in 1999 from the particularly felt need of sharing know-how, objectives and results between areas that until then seemed quite distinct such as bioengineering, medicine and singing. MAVEBA deals with all aspects concerning the study of the human voice with applications ranging from the neonate to the adult and elderly. Over the years the initial issues have grown and spread also in other aspects of research such as occupational voice disorders, neurology, rehabilitation, image and video analysis. MAVEBA takes place every two years always in Firenze, Italy.

Download or read book Acoustic Analysis of Internally Versus Externally Guided Speech in Parkinson's Disease written by Susannah Balestracci and published by . 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 2024-08-07 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Degeneration of nerve cells that control cognitive, speech, and language processes leading to linguistic impairments at various levels, from verbal utterances to individual speech sounds, could indicate signs of neurological, cognitive and psychiatric disorders such as Alzheimer’s disease (AD), Parkinson’s disease (PD), amyotrophic lateral sclerosis (ALS), dementias, depression, autism spectrum disorder, schizophrenia, etc. Currently, these disorders are diagnosed using specific clinical diagnostic criteria and neuropsychological examinations. However, speech-based biomarkers could potentially offer many advantages over current clinical standards. In addition to being objective and naturalistic, they can also be collected remotely with minimal instruction and time requirements. Furthermore, Machine Learning algorithms developed to build automated diagnostic models using linguistic features extracted from speech could aid diagnosis of patients with probable diseases from a group of normal population. To ensure that speech-based biomarkers are providing accurate measurement and can serve as effective clinical tools for detecting and monitoring disease, speech features extracted and analyzed must be systematically and rigorously evaluated. Different machine learning architectures trained to classify different types of disordered speech must also be rigorously tested and systematically compared.

Download or read book The Lombard Effect on Speech Clarity in Patients with Parkinson Disease written by Firas Saler Daher Alfwaress and published by . This book was released on 2008 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vocal loudness tends to increase when healthy speakers are speaking in the presence of background noise. Acoustic studies of Lombard speech have shown that other articulatory changes associated with increased intelligibility occur along with the increase in loudness. Lombard speech in healthy speakers is characterized by decreased speaking rate, increased fundamental frequency range and mean, as well as increased vowel space. These results suggest a more complex interaction between auditory monitoring of speech and motor speech planning in this uncommon speaking environment. Recently, there has been increased interest in the effect of background noise on speakers with Parkinson Disease (PD). In this study, nineteen patients with Mild-to-Moderate Idiopathic PD (10 males and 9 females) and 19 age-and-sex matched healthy speakers were recruited to investigate these acoustic-phonetic measures in quiet and in Lombard conditions. A 90 dB SPL noise was given binaurally via a closed headset to induce the LE. Subjects were engaged in repeating the syllable chain /pataka/ and reading a set of phonetically balanced sentences. Speaking rate was measured by the diadochokinetic (DDK) task and speech rate (SR). Vocal loudness measures included intensity (INT) and intensity standard deviation (INTSD). Fundamental frequency range (F0Rge), mean (F0M), and standard deviation (F0SD) were the acoustic measures of fundamental frequency. The vowel space (VS) was obtained by measuring the vowel quadrilateral of the corner vowels /i, æ, a, u/ in the vocal tract. Repeated measures ANOVA results showed a statistically significant increase in vocal loudness measures, increase in F0 measures, and a decrease in speaking rate measures in both groups as a function of noise. The VS was not statistically different for both groups of participants in the Lombard condition. The male speakers in both groups showed increased VS compared to their female counterparts. The Parkinsonian group showed a smaller VS area in both conditions. In particular, the PD patients with moderate severity showed centralized VS compared to the healthy participants. These findings suggest that speakers with PD utilize neuromotor planning for speech production with the same capacity as non-impaired speakers; however, this capacity tends to deteriorate as PD becomes advanced.
