Defektywne realizacje spółgłosek palatalnych dentalizowanych przy prawidłowych i nieprawidłowych warunkach zgryzowych. Wskazówki do terapii logopedycznej

The authors of the paper present the results of the research on the incorrect way of pronouncing the soft dentalized consonants as well as the range and regularity of the defect in the case of a person with open occlusion and with the correct one. The research shows that in both cases the defect consists in changing the palatal [ś ź ć v] into the palatalized [s’ z’ c’ r’] or even into the hard [s z c r]. However, the study does not only deal with the permanent substitution of the above-mentioned realisations but with the optional incorrect pronunciation that occurs alternatively with the correct one. In the position before a vowel the defective articulation even with distinctly heard [z] is a rule. What is more, [z] appears, although not so regularly, in the case of the right realisation of /ś ź ć v/ as well. The comparison of the pronunciation of a person with open occlusion and the correct one shows that the defect of occlusion does not influence the articulation of /ś ź ć v/. Certain phonetic factors resulting in the intensity of speech defects are more important here. For example, flattening lips during the articulation of a following vowel and the presence of other palatal dentalized sounds in a word or phrase. The conducted research provides certain tips helpful in logopedic therapy.
