| Summary: | The article is devoted to the analysis of the spectrographic characteristics of defective sounds pronunciation in children with minimal dysarthric disorders (mild dysarthria). These characteristics were obtained in the process of an experimental-phonetic study. It involved the study of the nature of changes that occur during the transition from one sound to another and also during the pronunciation of a single sound. The article presents the results of the experiment carried out on the basis of a qualitative analysis of dynamic spectrograms of syllables; describes the most permanent signs characterizing the defective sounds pronunciation in syllables of various structures (open, closed). The nature of the mutual influences of sounds in various structures of syllables is revealed. Comparative data were obtained for the acoustic (formant) proximity of various variants of defective pronunciation to the sound standard in children with minimal dysarthric disorders. The contextual phonetic influences at the level of syllables are determined, taking into account the acoustic characteristics of sounds and their defective variants. |
