Speech development in preschool children is crucial for their overall emotional, cognitive and physiological development. Speech is the basic means of communication that children acquire through interaction with the environment, and music can have a significant impact in stimulating this process. Through music, children develop rhythm and auditory abilities, articulation is stimulated and all this contributes to the development of speech. Speech disorders in children of a certain age can manifest themselves in different ways. Among the most common disorders is pronunciation disorder, which refers to improper articulation of sounds, and language difficulties that include problems with understanding and forming sentences. Other disorders such as rhythm and tempo disorders of speech, such as stuttering, haste and bradillalia, are also very important, as is a voice disorder that involves changes in the volume, pitch or quality of the voice. The causes of speech disorders can be varied, including genetic factors, neurological problems, hearing problems, and environmental factors such as lack of stimulation in early childhood. Recognizing the symptoms of speech disorders is crucial for adequate diagnosis and therapy. Speech therapy assessment and the use of specialized diagnostic methods make it possible to accurately determine the type and cause of the disorder. Early intervention is of great importance because it enables faster progress in therapy and prevents further difficulties in speech development. Speech therapy, adapted to the specific needs of the child, can significantly improve speech abilities. Prevention of speech disorders includes encouraging speech development from an early age, with the creation of a stimulating environment and regular check-ups by specialists. It is important to say that the role of parents and educators in the development of speech in children cannot be emphasized enough. Through everyday conversation, reading, play and interaction, children receive the necessary incentives for language acquisition and development. Furthermore, the education of parents and their involvement in the early identification and support of the child can significantly contribute to early diagnosis and success in the treatment of speech disorders. Taking care of a child's speech development from the earliest days lays the foundation for their successful professional and social life in the future.
