Language development is crucial to all aspects of children’s lives and is one of the best predictors of educational achievement. Many researchers have discussed speech delay because it is a communication barrier that often occurs in children. Speech delay is a speech disorder in children that has an impact on their social life. Even though there have been many studies on speech delay, not many of these studies have identified the types of speech delay that are most commonly found in children. Therefore, this review aims to describe the causes of speech delay that are most often experienced by children with speech delay. The method uses a systematic review method, namely analysing 15 research articles that examine cases of speech delay in a child. Data was collected using review techniques and grouping articles based on the factors that cause a child's speech delay. The results of the research show that most children who experience speech delays are caused by certain factors; therefore, a mother must pay close attention to her health throughout pregnancy until her children pass through the toddler years.
