Speech and language development is a complex process that takes place amongst children in a similar, but not the same way. Children learn the language in interaction with others, and it is our job to provide them with quality communication. Vocabulary enrichment and development takes place almost a lifetime. The aim of the study was to investigate how much kindergarten teachers deal with language acquisition in children, in what way, how much influence educators have on speech and language development, and whether children see progress in speech development. I conducted the research with an anonymous online survey intended for kindergarten teachers. The research showed that educators carry out a multitude of activities a week that encourage the development of speech, and the results of the research show how they deal with language acquisition. Educators are more likely to tell children stories and read picture books than to play language games with them or use rhymes and tongue twisters in their work, and over 80% of educators often talk to children and see progress in speech and vocabulary expansion. In conclusion, in order to enrich children's vocabulary and encourage speech and language development, it is important to be a quality role model, provide them with support and security and a stimulating environment. Encouraging research, asking questions, lots of love and understanding results in good speech and language development and the development of children's curiosity. It is important to talk to children every day, not just through kindergarten activities, and to pay attention to our expressions, pace of speech, tone and pitch because we are the child's speech role models and as educators and parents have one of the most important roles in a child's life and in overall development.
