The prosodic aspects of hypokinetic dysarthria in Parkinson's disease (PD) have been the focus of numerous reports. Few data on the effects of levodopa on prosody, more specifically on the effects on the variability of prosodic characteristics such as pitch, loudness and speech rate, are available in advanced PD. The relation between these characteristics(More)
It is commonly acknowledged that word or phoneme intelligibility is an important criterion in the assessment of the communication efficiency of a pathological speaker. People have therefore put a lot of effort in the design of perceptual intelligibility rating tests. These tests usually have the drawback that they employ unnatural speech material (e.g.,(More)
To improve ecological validity, perceptual and instrumental assessment of disordered voice, including overall voice quality, should ideally sample both sustained vowels and continuous speech. This investigation assessed the utility of combining both voice contexts for the purpose of auditory-perceptual ratings as well as acoustic measurement of overall(More)
Over the past several decades, many acoustic markers have been proposed to be sensitive to and measure overall voice quality. This meta-analysis presents a retrospective appraisal of scientific reports, which evaluated the relation between perceived overall voice quality and several acoustic-phonetic correlates. Twenty-five studies met the inclusion(More)
Intelligibility is a primary measure for the assessment of pathological speech. Traditionally, it is measured using a perceptual test, which is by definition subjective in nature. Consequently, there is a great interest in reliable, automatic and therefore objective methods. This paper presents such a method that incorporates an automatic speech recognizer(More)
The effect of speech rate on overall intelligibility in Parkinson's Disease (PD) is still a matter of debate. A comparison of the results of previous studies on speech rate in PD is hampered by methodological differences. In this study, we evaluated the effects of levodopa on speech rate and on its variability in a standardized reading task. Twenty-five(More)
OBJECTIVE In persons with a speech pathology, improved intelligibility is the fundamental goal of treatment. Identification of specific phonetic features that affect intelligibility, contributes to selecting intervention targets. The main purpose of this study was to investigate whether a segmental analysis based on a perceptual phoneme intelligibility(More)
This paper considers an inventory problem on a multi-stage, serial system. The demand for the end item is stochastic and stationary. The relevant costs include a fixed ordering cost and an echelon inventory holding cost for each stage, and a backorder cost for the end item. The objective is to find a continuous-review inventory control policy that minimizes(More)
INTRODUCTION Severe tinnitus can seriously impair patients in their activities in daily life and reduce their quality of life. The aims of this prospective clinical study were to assess the long-term effects of cochlear implantation (CI) on tinnitus in patients with single-sided deafness and ipsilateral incapacitating tinnitus, and to investigate whether CI(More)
