Comparative analysis of the state of timbre disorders and acoustic characteristics in students with voice and hearing impairments

<jats:p>&lt;p&gt;&lt;em&gt;Abstract&lt;/em&gt; &lt;strong&gt;Context and relevance. &lt;/strong&gt;The polysensory analysis of the components of speech activity plays a special role in the formation of phonation. Taking into account the specifics of the state of resonance balance among different categories of students with special educational needs, it is necessary to rationally approach the selection of technologies and the content of correctional and developmental work. The search for effective and adequate speech therapy techniques for primary school students with primary and secondary vocal tone disorders and their reasonable combination are an integral part of the modern correctional education system.&lt;strong&gt; Objective. &lt;/strong&gt;To evaluate the specific characteristics of vocal tone disorders in students with voice disorders (dysphonia) and hearing disorders and their impact on the formation of acoustic components of self-esteem.&lt;strong&gt; Methods and materials. &lt;/strong&gt;The materials of an experimental study, which was of a comparative nature, are presented. The study involved 69 primary school age students, of whom 39 children were diagnosed with dysphonia and 30 &amp;mdash; with hearing disorders of varying severity. The developed program for the diagnosis of developmental disorders consisted of two stages, allowing to assess the state of the motor skills of the soft palate in involuntary and voluntary terms; auditory and acoustic assessment of the timbre of the voice.&lt;strong&gt; Results. &lt;/strong&gt;The relevance of the study and the importance of the acoustic control condition for the selection of correctional and developmental learning technologies is proved; the specific characteristics of the disorders under study are established.&lt;strong&gt; Conclusions. &lt;/strong&gt;The presented materials make it possible not only to judge the need for an interdisciplinary approach to correcting voice disorders in primary and secondary speech pathology, but also to improve the quality of speech therapy work.&lt;/p&gt;</jats:p>
