Purpose: The human voice changes with the progression of neurological disease and the onset of diseases that affect articulators, often decreasing the effectiveness of communication. These changes can be objectively measured using signal processing techniques that extract acoustic features. When measuring acoustic features, there are often several…

This paper addresses the techniques of treating patients with functional disorders of pronouncing sibilants in Arabic. The sounds under question are /s/, /z/, /?/. The main disorders that are studied here are: substitution and distortion. A descriptive analytical approach was followed; patients from different ages of functional pronunciation…

The three types of stresses namely "word stress," "compound stress" and "phrasal stress" are the key elements to determine the exact means of conveying a specific intent in an utterance. Therefore during perception and production of such meaning carrying codes, being able to use the right stress pattern is vitally…

This brief article reflects on some pitfalls inherent in the learning and teaching of segmental phonetic transcription. We suggest that a gestural interpretation to disordered speech data, in conjunction with segmental phonetic transcription, can add valuable insight into patterns of disordered speech, and that a gestural orientation should form…

Notes that in phonetic categorization, listeners hear a range of speech sounds forming a continuum of ambiguous sounds between two endpoints and are required to identify the sounds as one or other of the endpoints. Points out that this task has been used in phonetics and in psycholinguistics to study categorical perception, selective adaptation,…

The experimental addition of speech output to computer-based Esperanto lessons using speech synthesized from text is described. Because of Esperanto's phonetic spelling and simple rhythm, it is particularly easy to describe the mechanisms of Esperanto synthesis. Attention is directed to how the text-to-speech conversion is performed and the ways…
