Abstract. Currently, the number of children in need of correctional assistance is increasing in many countries of the world. According to the World Health Organization, speech disorders of various degrees are currently observed in an average of 30% of children admitted to the first grade, that is, when viewed objectively, during the preschool period, speech functions do not develop at the standard level in one third of the children's population and require additional corrective action from specialists. On the contrary, it is determined that phonetic-phonemic defects of speech (disorders in the pronunciation of sounds) appear in 15-25 per cent of the general population of children. According to the US National Centre for Health Statistics, voice disorders (articulatory or phonological disorders) in preschool children are 8-9 per cent. 5 per cent of children admitted to the first grade have speech defects such as speech disorders, stuttering, and dysarthria.
