The development of children's speech is a very complex and subtle process, which takes place under the influence of many different factors. Speech is a social phenomenon and its development is possible only in the conditions of the human environment. The family is the closest and the most natural child’s environment and therefore has the greatest role in the process of child development, including speech development. For many of today's children can be said to have poor language. Early recognition of deviations and early interventions are extremely important because delayed and inadequate speech development is one of the main causes of later learning difficulties. The third chapter describes in more detail the most common speech disorders in the general population of children, "Articulation disorders", their causes and prevention. The fourth chapter describes language difficulties and the reasons why language-speech disorders occur. The fifth chapter describes speech rhythm and tempo disorders, while the sixth chapter describes voice disorders and the prevention of voice disorders in children. The next chapter describes aphasia and dysphasia, i.e. the difficulties that arise due to the effect of brain damage on communication. When the development of finger movements corresponds to the age, speech development is also normal. When the development of fine motor skills lags behind, the development of speech also lags behind. The eighth chapter, which describes the interdependence of speech and motor skills, tells us about this. The game is man's natural activity. It allows a person to develop physically, intellectually, emotionally, spiritually, socially. Therefore, the ninth chapter describes language games for stimulating the correct development of speech. Particular emphasis is placed on songs in the form of games for speech development because it is easier for children to accept speech teaching material if it is rhythmic and accessible to visualization, and the song has exactly these qualities. In addition to songs in the form of games, finger games also have a special meaning, which will also be described in more detail in the ninth chapter. Finally, the stimulating of speech development will be described as well as the way in which language and speech development should be constantly stimulated because properly developed language and speech are prerequisites for the appropriate development of the child.
