Children start acquiring speech as a language activity from an early age. Speech development is a spontaneous and natural developmental process, but this development requires the influence of the environment. The parent is the first model that communicates with the child and has a great and important influence on him. After the family environment, the child comes to kindergarten and educators become the second most important models and promoters of children's speech development. Speech development is a spontaneous process and there are clearly defined developmental stages, however, it should be kept in mind that it is an individual process in which each child acquires language at a certain pace and dynamics. In most children, the language acquisition process takes place without difficulty, but in some cases, there may be certain physiological delays. While some children have more severe difficulties that result in language and speech difficulties. In the first part of the paper, the speech and language development of the child is described, as well as the difficulties that may arise in it. It also describes the influence of educators on speech and language development, as well as the activities and incentives that educators carry out with children. In the second part of the paper, research was conducted in the form of a survey containing 15 questions. The results showed that educators play a very important role in the development of speech in kindergarten and preschool children and that some educators are not considered sufficiently competent and educated for the conducted activities related to the stimulation of speech and language development with children with speech difficulties.
