Dysarthria is a neuromotor impairment of speech that affects one or more of the speech sub-systems. It is reflected in the acoustic characteristics of the phonemes as deviations from their healthy counterparts. To capture these deviations, in this work a continuous speech, an isolated-style monophone-based, and a triphone-based speech recognition systems are developed. These speech recognition ...

In this paper, assessment of ASR systems with a limited set of speech data selected from a larger testing corpus was studied for connected Dutch digits. Three methods of data selection were applied, namely random, knowledge-based, and datadriven selection. The goal of this study was to find out whether reliable assessment of speech recognition systems can be achieved by using a small sample of ...

My response to Fey's article (1985; reprinted 1992, this issue) focuses on the confusion caused by the application of simplistic phonological definitions and models to the assessment and treatment of children with speech delays. In addition to having no explanatory adequacy, such definitions/models lead either to assessment and treatment procedures that are similarly focused or to procedures th...

OBJECTIVES The purpose of this study was to investigate the motor profile of 125 children with developmental speech and language disorders and to test for differences, if any, in motor profile among subgroups of children with developmental speech and language disorders. METHODS The participants were 125 children with developmental speech and language disorders aged 6 to 9 years from 2 special...

Cognitive assessment in clinic represents time consuming and expensive task. Speech may be employed as a means of monitoring cognitive function in elderly people. Extraction of speech characteristics from speech recorded remotely over a telephone was investigated and compared to speech characteristics extracted from recordings made in controlled environment. Results demonstrate that speech char...

Low rate coders based on the harmonic-noise model are sensitive to acoustic background noise at low SNRs due to the increase in parameter errors from the analysis of noisy speech. We investigate the use of spectral subtraction enhancement preprocessing on the performance of the sinusoidal model based codec both by objective assessment of parameter errors and the subjective testing of output spe...

INTRODUCTION Acoustic evaluation of alaryngeal voices is among the most prominent issues in speech analysis field. In fact, many methods have been developed to date to substitute the classic perceptual evaluation. The Aim of this study is to present our experience in erygmophonic speech objective assessment and to discuss the most widely used methods of acoustic speech appraisal. through a pros...

Tongue bifurcation (also called 'splitting' or 'forking') is an increasingly popular cosmetic procedure in the body modification community that involves splitting the anterior tongue down the centre line. The implications of this procedure for speech have not been systematically studied; a few case studies have been published and suggest that there may be effects, primarily on fricatives. This ...

This paper presents a new concept of an e-learning system with intelligent two-way speech communication between the system and its users. Computational intelligence methods allow for analysis, evaluation and assessment of user’s knowledge and skills and user’s ability for efficient information processing. The system is also capable of control, supervision and optimization of the e-learning proc...
