Reliability and Clinical Relevance of Segmental Analysis Based on Intelligibility Assessment Universiteit Gent
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 assessment is reliable and can be used for target selection. Secondly, the hypothesis that ...
Time and Frequency Dependent Amplification for Speech Intelligibility Enhancement in Noisy Environments Vrije Universiteit Brussel
When speech is presented through loudspeakers in a noisy environment, the background noise can significantly decrease speech intelligibility. Because the amplitude and spectrum of the background noise can vary over time (and because high loudness levels are to be avoided for listener comfort), choosing proper speech equalization and master gain settings for a public address system can be a difficult task. In this paper, we propose an adaptive ...
Articulation lost in space : the effects of local orobuccal anesthesia on articulation and intelligibility of phonemes Universiteit Gent
Motor speech requires numerous neural computations including feedforward and feedback control mechanisms. A reduction of auditory or somatosensory feedback may be implicated in disorders of speech, as predicted by various models of speech control. In this paper the effects of reduced somatosensory feedback on articulation and intelligibility of individual phonemes was evaluated by using topical anesthesia of orobuccal structures in 24 healthy ...

Intelligibility Required: How to make Us Look Smart Again Universiteit Hasselt
Users often become frustrated when they are unable to understand and control a ubicomp environment. Previous work has suggested that ubicomp systems should be intelligible to allow users to understand how the system works and controllable to let users intervene when the system makes a mistake. In this paper, we identify several design considerations for supporting intelligibility and control in ubicomp environments. We show these considerations ...
Objective intelligibility assessment of pathological speakers Universiteit Gent
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 (ASR) for producing features that characterize the pronunciations of a speaker and an ...
Impact of speech rate and mouth opening on hypernasality and speech intelligibility in children with a cleft (lip and) palate Universiteit Gent
Aim: this study evaluated the effectiveness of different speech techniques (i.e. modification of speech rate and/or mouth opening) for the rehabilitation of hypemasality in children with a cleft palate with or without a cleft lip (CP +/- L). The impact of speech rate and/or mouth opening was investigated on both hypemasality and speech intelligibility. Methods: thirteen patients with CP L and perceived hypemasality (mean age: 10y5m) and 13 age ...
The influence of oral health status on speech intelligibility, articulation and quality of life of older community-dwelling people Universiteit Gent
Objective: To investigate the impact of the oral health status on speech intelligibility, articulation and quality of life of older community-dwelling people. Background To our knowledge, there have been no studies on this topic in patients aged 75 years or older.Material and methods: Thirty outpatients of a university dental clinic (median [IQR] age of 77.00 [75-82] years) participated. The OHIP-14, a dental examination, a speech ...
Intelligibility of filtered speech and its relation to electrophysiological markers of supra-threshold hearing deficits Universiteit Gent
The origins and perceptual consequences of supra-threshold hearing deficits are not well understood. Sensory and neural deficits are likely contributors, underlining the need for an objective measure which quantifies the neural contributors and complements audiometric measures of sensory loss. The envelope-following response (EFR) is sensitive to neural fiber loss in animal models and has been proposed as a marker. However, its diagnostic ...
