The study of spontaneous speech is considered one of the most important problems in linguistics today. The main reason for this is the attempts to automate speech. Despite the fact that artificial intelligence systems are currently performing both written and spoken speech, the process of automating human speech is not over. After all, language is a complex system, and automating all its cultural and social aspects is not an easy task. In addition, it is necessary to take into account age aspects in the use of language. The tempo, timbre, and manner of speaking change as a person ages. It is even possible to estimate a person's age through these aspects. The speech of older people has served as the object of many studies. However, the study of children's speech lags behind in this regard. This article discusses the need to study children's speech and when this category of studies began.
