In this final paper, importance is attached to the interaction of speech with other activities with children of early and preschool age. Speech is associated with all activities. We pay attention to its development and its necessary to work on it from child’s birth. The aim of this paper is to confirm the importance of the interaction of speech with other activities as a prerequisite for the overall development of children. The conducted research showed that there is an inevitable connection between various activities (art, music, physical, etc.) with the development of speech. Through such activities the child's motor skills develop as a prerequisite for speech, but also for many mental functions such as intelligence, memory, attention and auditory perception. The research shows individuality in children, but also some difficulties that today's children encounter during speech development. This final paper offers insight into research with children of mixed nursery and mixed kindergarten groups. I observed how speech is development and encouraged childrens speech expression through various activities.
