The purpose of the paper is to identify effective methods based on an interdisciplinary approach in tackling speech disorders in children via the study of two groups of respondents, with the various applications of corrective measures. As a result, in the Experimental group (EG) the indicators of producing hushing sounds are lower in comparison with the Control group (CG). In conclusion, a well-formed differentiation of the movements of the organs of articulation and the completeness of the kinesthetic sensations of various positions of the tongue in the oral cavity is required for the development of pronunciation.
