Exploring The Temporal Variability Of Speech Intensity, Speech Intelligibility, And Communicative Participation In Individuals With Hypophonia And Parkinson’S Disease, Cynthia Mancinelli
Exploring The Temporal Variability Of Speech Intensity, Speech Intelligibility, And Communicative Participation In Individuals With Hypophonia And Parkinson’S Disease, Cynthia Mancinelli
Electronic Thesis and Dissertation Repository
Hypophonia, or reduced speech intensity, is frequently observed in individuals with Parkinson’s disease (PD). This speech deficit can impact speech intelligibility and communicative participation. However, there is little empirical evidence exploring the day-to-day variability of speech and communicative participation in individuals with PD. The purpose of this study is to investigate the temporal variability of acoustic and perceptual speech measures and psychosocial measures in individuals with hypophonia and PD. Additionally, this study seeks to examine the relationships among measures of speech intensity, speech intelligibility, self- and proxy-rated communicative participation, demographic factors, and non-speech factors. Twenty-three participants with PD, 23 primary …
Changes In Speech Intelligibility And Acoustic Distinctiveness Along A Speech Rate Continuum In Parkinson’S Disease, Thea Knowles
Changes In Speech Intelligibility And Acoustic Distinctiveness Along A Speech Rate Continuum In Parkinson’S Disease, Thea Knowles
Electronic Thesis and Dissertation Repository
Asking a person to speak slowly is a common technique in speech therapy for people with Parkinson’s disease (PD). Slowed speaking rates are thought to bring about changes in speech production that make it easier for people with speech impairments associated with PD to be understood, but this is not always the case. Furthermore, research suggests that using faster speech does not necessarily lead to decreases in speech intelligibility for some people with PD. Most studies of rate modification in PD have only included one or two rate adjustments to investigate the relationship between speech rate, intelligibility, and acoustic aspects …
The Effect Of Botulinum Toxin Type A On Speech Intelligibility In Oromandibular Dystonia, Beatriz Ysabel Domingo
The Effect Of Botulinum Toxin Type A On Speech Intelligibility In Oromandibular Dystonia, Beatriz Ysabel Domingo
Electronic Thesis and Dissertation Repository
Speech intelligibility of 10 individuals with OMD was measured before and after receiving BoNT-A injections. Intelligibility was assessed using the PIT (single-word intelligibility), SIT (sentence intelligibility), and a conversational speech task. Five listeners rated the speech intelligibility of these three intelligibility tasks via orthographic transcription and visual analogue scaling (VAS) techniques. BoNT-A was not associated with significant differences in speech intelligibility. Further analysis revealed a significant difference on the PIT VAS intelligibility ratings based on order of presentation, suggesting that listeners rated the first half of words on the PIT (words 1-29) as more intelligible than the second half of …
A Comparison Of Speech Amplification Devices For Individuals With Parkinson's Disease And Hypophonia, Monika Andreetta
A Comparison Of Speech Amplification Devices For Individuals With Parkinson's Disease And Hypophonia, Monika Andreetta
Electronic Thesis and Dissertation Repository
One of the most prevalent speech impairments in idiopathic Parkinson’s disease (PD) is hypophonia, a reduction in intensity, which typically decreases intelligibility. Speech amplification devices are a potential solution; however, despite the availability of a broad range of devices, no previous studies systematically compare their efficacy in PD. This study examined the effects of speech task (Sentence Intelligibility Test versus conversation), background noise (no noise versus 65 dB SPL multi-talker noise), and selected devices (ADDvox, BoomVox, ChatterVox, Oticon, SoniVox, Spokeman, and Voicette) for 11 PD and 10 control participants, using outcome measures of speech intensity, speech-to-noise ratio, intelligibility, sound quality, …
Effects Of Coordinated Bilateral Hearing Aids And Auditory Training On Sound Localization, Iman Elsabah Ibrahim
Effects Of Coordinated Bilateral Hearing Aids And Auditory Training On Sound Localization, Iman Elsabah Ibrahim
Electronic Thesis and Dissertation Repository
This thesis has two main objectives: 1) evaluating the benefits of the bilateral coordination of the hearing aid Digital Signal Processing (DSP) features by measuring and comparing the auditory performance with and without the activation of this coordination, and 2) evaluating the benefits of acclimatization and auditory training on such auditory performance and, determining whether receiving training in one aspect of auditory performance (sound localization) would generalize to an improvement in another aspect of auditory performance (speech intelligibility in noise), and to what extent. Two studies were performed. The first study evaluated the speech intelligibility in noise and horizontal sound …
The Effect Of Multitalker Background Noise On Speech Intelligibility In Parkinson's Disease And Controls, Talia M. Leszcz
The Effect Of Multitalker Background Noise On Speech Intelligibility In Parkinson's Disease And Controls, Talia M. Leszcz
Electronic Thesis and Dissertation Repository
This study investigated the effect of multi-talker background noise on speech intelligibility in participants with hypophonia due to Parkinson’s disease (PD). Ten individuals with PD and 10 geriatric controls were tested on four speech intelligibility tasks at the single word, sentence, and conversation level in various conditions of background noise. Listeners assessed speech intelligibility using word identification or orthographic transcription procedures. Results revealed non-significant differences between groups when intelligibility was assessed in no background noise. PD speech intelligibility decreased significantly relative to controls in the presence of background noise. A phonetic error analysis revealed a distinct error profile for PD …
