In this thesis, the role of the preschool teacher as a speech model in the kindergarten and the general influence of the preschool teacher on the proper development of children's speech were investigated. Speech development begins immediately after the birth of a child and develops less intensively during the first three years of life. A key component of children's speech development is listening, therefore the fundamental role of preschool teachers in speech development consists in encouraging conversation, correct pronunciation of words and correcting pronunciation disorders. For preschool teachers to adequately fulfill their role as speech models, they must constantly educate themselves, create a stimulating environment for speech development, and develop trust with children so that they feel safe participating in the conversation. In the final paper, the preschool teachers' answers to the questions asked through the interview are presented, which emphasize the attitudes and opinions of the teachers regarding the role of the educator as a speech model. Preschool teachers emphasized the need for constant training, the significant impact of screening on the increasing frequency of pronunciation disorders, and listed various stimulating methods used in their daily work to encourage the proper development of children's speech.
