Critical Review: Does Delayed Auditory Feedback Improve Speech Intelligibility in Parkinson’s Disease?
نویسنده
چکیده
This critical review examines the effect of delayed auditory feedback (DAF) on speech intelligibility in Parkinson’s disease. Each of the eight articles included in this review examines speech rate and intelligibility with the use of DAF in patients with Parkinson’s disease. Three of the eight articles found positive effects on intelligibility with the use of DAF and five of the eight articles found negative or no effects on intelligibility while using DAF. The outcomes of these studies indicate mixed evidence for improvements in intelligibility in Parkinson’s disease with the use of DAF.

Factors Influencing the Effects of Delayed Auditory Feedback on Dysarthric Speech Associated with Parkinson’s Disease
Purpose:The present study examined the effects of Delayed Auditory Feedback (DAF) as a rate control intervention for dysarthric speakers with Parkinson's disease.Adverse reactions to relatively long delay intervals are often observed during clinical use of DAF, and may result from improper "matching" of the delayed signal.To facilitate optimal use of DAF, clinicians may need to provide instruct...

The purpose of this second of two related papers is to present detailed clinical applications of delayed auditory feedback (DAF) in treating the speech rate and fluency deficits in speakers with Parkinson’s disease. For optimal results from DAF, clinicians should provide the speaker with instruction, modeling, and feedback. Toward that goal, the contributions of clinician instruction on the eff...

Abstract Background: The aim of this study was to determine the auditory performance of congenitally deaf children and the effect of cochlear implantation (CI) on speech intelligibility. Methods: Aprospective study was undertaken on 47 children in a pediatric tertiary referral center for CI. All children were deaf prelingually and were younger than 8 years of age. They were followed up until 5...

Purpose: Speech perception in participants with auditory neuropathy (AN) was systematically studied to answer the following 2 questions: Does noise present a particular problem for people with AN? Can clear speech and cochlear implants alleviate this problem? Method: The researchers evaluated the advantage in intelligibility of clear speech over conversational speech in 13 participants with AN....
متن کاملDirectly Comparing the Listening Strategies of Humans and Machines
1. MOTIVATION • Human listeners are much better at recognizing speech in noise than automatic speech recognition (ASR) systems – Understanding why could directly improve ASR noise robustness • We utilize the recently introduced “auditory bubbles” technique to compare the cues used by humans and ASRs (Mandel, 2013; Mandel et al., 2014) 1. Measure the intelligibility to listeners of the same spee...
