Summary: Audiological, phoniatric, psychological, psychiatric,
neurological, orthodontic, logopedic and phonetic data (40 variables) are
being collected on a sample of 75 children with articulation disorders,
between the ages 6 to 8. Data analysis is expected to address the problem
of causes of functional articulation disorders in order to improve
differential diagnostic techniques and create new, also differential,
procedures during therapy. Voice will be studied through perceptual
description and categorization of voices and dysphonic disorders, which is
a process of psychosomatic summations and averaging of the modulated
speech sound. In this way, objective acoustic correlates will be
determined on electroacoustic computer operated apparatus. This apparatus
will also measure average fundamental frequency values and voice
intensity, and display average spectrum for 60-second speech segments.
This objective procedure will be applied in monitoring voice changes as
well, which will be perceived auditorily, induced by control of a healthy
voice or rehabilitation of a dysphonic one.
Research goals: Articulation errors are the most frequent speech
disorders which, according to some authors, can be found in 35% of
preschool children and in 12 to 15 % children of school age. The aim of
this research is to determine the factors causing articulation disorders,
in order to apply suitable treatment for their elimination. We believe that
this would have better effects on related disorders, among which reading
and writing disorders are the most frequent. Nearly 20% of population have
voice disorders, which differ in their phenomenology and etyology. This
research will attempt to isolate the hereditary factor, whereas
phenomenology will be more strictly determined through a classification
based on three objectively measurable factors: average speech fundamental,
average speech loudness (of normal speech and maximally loud speech) and
average spectral form of speech. The results of this investigation may
create a basis for preventive measures and design of health protection
programs, as well as a basis for different approaches to treatment of
articulation and voice disorders. Other information about the project.
