Speech delay is one of the developmental disorders that often occurs in early childhood, affecting
approximately 5–10% of preschool-age children globally. This phenomenon can have significant impacts on
children’s communication, social, and academic development. This study aims to analyze the causative
factors, impacts, and effective intervention strategies in dealing with speech delay through a literature review
approach. The method used involves searching for and critically analyzing various relevant scientific sources
published between 2019–2024 from the Google Scholar database using keywords “speech delay”, “children’s
language development”, and “speech delay intervention”. The results of the study show that biological factors
(genetics, birth weight, premature birth, neurological disorders), environmental factors (lack of verbal
stimulation, excessive gadget exposure, multilingual environment), and psychosocial factors (parental
education level, working mothers, family stress) collectively contribute to the occurrence of speech delay.
Early intervention involving the active role of parents and professionals has been proven effective in
overcoming speech delay in children. This review emphasizes the importance of early detection and holistic
approaches that integrate family involvement, professional guidance, and targeted therapeutic interventions
to support optimal language development in children
