Loudness Matching In Individuals With Parkinson’S Disease And Hypophonia, Catherine Johnson
Loudness Matching In Individuals With Parkinson’S Disease And Hypophonia, Catherine Johnson
Electronic Thesis and Dissertation Repository
The purpose of the present study was to investigate speech loudness perception in 15 individuals with Parkinson’s disease (IWPD) and hypophonia (reduced speech intensity) and 15 healthy control (HC) participants. A loudness matching procedure was used to examine conditions involving speech loudness targets presented at various levels (60 to 80dB SPL). The loudness response conditions included manually controlled audio playback of external speech, self-vocalized speech, amplified self-speech, and speech projected to a distance of 2 meters. For most of the loudness matching conditions, the PD group did not demonstrate the predicted deficit in loudness matching. In some loudness matching conditions, …
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 …
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, …
The Effect Of Concurrent Cognitive, Linguistic And Motor Tasks On Speech Intensity In Parkinson’S Disease, Teresa J. Valenzano
The Effect Of Concurrent Cognitive, Linguistic And Motor Tasks On Speech Intensity In Parkinson’S Disease, Teresa J. Valenzano
Electronic Thesis and Dissertation Repository
This study investigated the effect of concurrent tasks on speech intensity in Parkinson’s disease (PD). Thirteen PD participants and twenty-two controls performed three tasks concurrent with a speech task. The speech task involved a repeated carrier phrase and a target word. The concurrent tasks involved math addition (cognitive), verb generation (linguistic), and manual visuomotor tracking (motor) at three levels of difficulty. All three concurrent tasks were associated with reduced speech intensity relative to the isolated speech task. The concurrent motor task was generally associated with the greatest reduction in speech intensity. Task performance measures were not significantly different for the …
Loudness Perception And Speech Intensity Control In Parkinson's Disease, Jenna Paula Clark
Loudness Perception And Speech Intensity Control In Parkinson's Disease, Jenna Paula Clark
Electronic Thesis and Dissertation Repository
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 …
