An acoustic model of pathological voice production is presented. It describes the non-linear effects occurring in the acoustic waveform of disordered voices. The noise components such as fundamental frequency and amplitude irregularities and variations, sub-harmonic components, turbulent noise and voice breaks are formally expressed as a result of random time function influences on the excitati...

BACKGROUND Historically, the complete removable denture is the last prosthetic procedure to switch to digital techniques whose advantages are mainly observed in the laboratory stages; however, it is not possible to measure the depressibility of the oral mucosa using optical cameras, thus conventional impression techniques are still necessary. This article describes the clinical and laboratory p...

proper speech functioning in human being, depends on the precise coordination and timing balances in a series of complex neuro nuscular movements and actions. starting from the prime organ of energy source of expelled air from respirato y system; deliver such air to trigger vocal cords; swift changes of this phonatory episode to a comprehensible sound in resonace and final coordination of all h...

This paper addresses the problem of Computer-Aided Speech and Language Therapy (CASLT). The goal of the work described in the paper is to develop and evaluate a semi-automated system for providing interactive speech therapy to the increasing population of impaired individuals and help professional speech therapists. A discussion on the development and evaluation of a set of interactive therapy ...

Improved methods for assessing bulbar impairment are necessary for expediting diagnosis of bulbar dysfunction in ALS, for predicting disease progression across speech subsystems, and for addressing the critical need for sensitive outcome measures for ongoing experimental treatment trials. To address this need, we are obtaining longitudinal profiles of bulbar impairment in 100 individuals based ...
