This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall purpose of this dissertation was to identify the effects of delayed auditory feedback (DAF) on speech motor stability and speech fluency in normally fluent adults (PWNS) and to compare them with effects on adults who exhibit persistent stuttering. If the auditory processing influences differently the two groups, it might shed light on the basic role of auditory-to-motor integration in speech production. Differences in auditory feedback dependency were also expected between normally fluent individuals who are highly susceptible to DAF and normally fluent individuals who are minimally affected by DAF. Three studies were conducted to (I) subgroup 62 normally fluent males and females based on their responses to DAF during spontaneous conversational speaking and reading tasks, (II) compare responses to DAF between 15 normally fluent adults who showed high stuttering-like disfluencies (SLD) under DAF (High-SLD group), 15 normally fluent adults who showed low SLD under DAF (Low-SLD group), and 15 adults who stutter, and (III) compare the specific effects of DAF on speech motor stability and movement patterns (lower-lip movement) in 11 normally fluent adults versus 11 adults who stutter. Study I revealed that normally fluent participants, as a group, increased the amount of SLD and speech errors (SE), and decreased articulation rate (AR) when speaking under DAF relative to speaking under amplified non-delayed condition (aNAF). Sex had a limited differential effect on other disfluencies (OD) and AR whereas task effects were seen in OD, SE, and AR. Neither sex nor task, however, did influence SLD. Three subgroups, Low, Middle, and High Responders were identified. There were clear differences between the Low and High Responders in that the Low Responders exhibited smaller numbers of SLD and SE as well as faster AR than the High Responders. The Middle Responders revealed task dependency, showing different responses than those exhibited by the Low and High Responders. The results of Study II showed that people who stutter did not reduce SLD counts under DAF condition, a finding that deviates from reports of previous studies. PWS also exhibited higher mean number of SLD than the normally fluent Low-SLD group but similar to that of normally fluent High-SLD group. For all groups, the number of SE was higher and AR was slower under DAF than aNAF. PWS showed larger individual variability in responses to aNAF compared to natural feedback conditions in that some PWS reduced SLD under aNAF condition. Study III revealed significant difference between PWS and PWNS in speech kinematic stabilities, showing that PWS exhibited higher spatio-temporal index (i.e., lower speech motor stability) than PWNS across auditory feedback conditions in four utterance stimuli. PWS, however, yielded higher speech movement stability under aNAF and 25ms-DAF in longer stimuli compared to natural feedback condition. There was no group difference in movement displacement and velocity for opening-closing sequential movements but the patterns were different in each group. PWNS showed lower displacement and velocity under aNAF and DAF compared to natural feedback condition for both opening and closing movements whereas PWS showed higher displacement under DAF than aNAF condition and higher velocity under nNAF than 25ms-DAF. Normally fluent people showed shorter movement duration and faster articulation rate than PWS across auditory feedback and stimuli. This dissertation study has demonstrated different influences of auditory feedback on speech motor control in normally fluent adults and adults who stutter. In both groups, individual variability was obvious. In normally fluent adults, diverse responses to DAF could be explained with different auditory feedback dependency for ongoing speech articulatory production. PWS were more dependent on auditory feedback for speech production, and auditory-to-motor integration under aNAF and short delay feedback conditions helped them to improve speech motor stability.

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 excerpt: This study was designed to examine the effects of delayed auditory feedback (DAF) on the speech kinematics of normal speakers. The procedure involved collecting jaw, upper and lower lip kinematics for closing gestures, using strain gauges during 4 different DAF conditions (0, 40, 80, and 120 msec delay). An acoustic analysis of utterance duration revealed that rate of speech became slower across increases in DAF. The main kinematic findings were that movement time, percent time to peak velocity, and the number of velocity peaks increased with increases in DAF. Additionally, peak velocity and the peak velocity/maximum displacement ratio decreased with increases in DAF. Maximum displacement showed a consistent increase across DAF settings for jaw movements but not for upper and lower lip movements. These kinematic results appear to be in general agreement with previous kinematic studies of slow speech.

Available in PDF, EPUB and Kindle. Book excerpt: Motor learning relies on the integrity of sensorimotor circuits in the brain, which are largely affected in individuals with Parkinson disease (PD). Additionally, data suggest normal aging can affect various stages of motor learning. Though data are available on the nature of non-speech motor learning, fewer studies have examined how adults with and without motor speech disorders learn speech articulatory sequences. The aim of the current investigation is to examine speech motor sequence learning in normal aging and PD. A speech motor sequence learning task was developed and implemented to examine acquisition, consolidation, and automatization over two days. On Day 1, participants learned a sequence of six monosyllabic nonwords to examine acquisition. This speech motor sequence was re-tested on Day 2 in single- and dual-task conditions to evaluate consolidation and automatization, respectively. Learning was inferred from gains in speed and accuracy of the speech motor sequence. There were no observed effects of aging or PD on speech motor sequence acquisition, as all groups exhibited comparable gains in speed and accuracy on Day 1. However, aging and PD were observed to affect speech motor consolidation following night-time sleep. Specifically, at the Day 2 re-test, young adults exhibited offline gains in speed and accuracy, older adults maintained speed and accuracy (without offline gains), and individuals with PD exhibited offline losses in speed. Only younger adults demonstrated automatization, exhibiting negligible dual-task effects when concurrently performing the speech motor sequence with a visuo-motor task. Conversely, both older adults and individuals with PD exhibited significantly poorer performance of the speech motor sequence in the dual-task condition, with individuals with PD experiencing the largest degree of bidirectional dual-task interference. Overall, the current findings suggest that speech motor learning is affected by both Parkinson Disease and normal aging. Data from the current investigation are largely in line with findings in the non-speech motor sequence learning literature, suggesting that speech and non-speech motor learning may rely on similar neural circuits. As the individuals with PD exhibited deficits in the consolidation and automatization phases of learning, these data may hold important implications for the speech rehabilitation in PD.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of divided attention on speech in Parkinson’s disease (PD) have been studied for a variety of tasks in recent years. Much of the previous research studied gait patterns while participants concurrently performed another task. There have been few studies regarding the effects of divided attention on speech in individuals with PD. The ability to communicate effectively relies in part on an appropriate rate of speech, vocal intensity, and fundamental frequency control. This study included 27 participants: 8 with PD, 12 neurologically healthy older (HO) adults, and 7 healthy younger (HY) adults. Each participant was given a list of topics to speak about during the experiment. They produced monologues under three conditions: standing, walking on a treadmill, and walking over obstacles on a treadmill. Each monologue was recorded and trimmed of pauses between topics, experimenter speech, and nonspeech behaviors before analysis. Speech rate, speaking versus pausing time, overall intensity, and intensity and fundamental frequency (F0) variability were analyzed. Median, mean, maximum, and minimum F0 increased as the gait task increased in difficulty. Mean and standard deviation of intensity also increased with gait demands. All groups had increased intensity variability when walking compared to standing. Speaking versus pausing time did not differ significantly as a function of the walking task and the results varied across the groups; the same was true for speech rate. These findings reflect changes in performance during divided attention tasks, with a greater effect on HO adults and individuals with PD than their younger counterparts.
