Communication is part of human everyday life and people can communicate in different ways. One of the ways is verbal communication. To understand the speech expression of an individual, it is important to know the segments on which it depends. Speech is a combination of voice and text, a way a person can expresses their thoughts and feelings. The success of such expression depends on elements such as speech fluency and communication competence, the knowledge and development of which contributes to a more fluent and comprehensible speech expression. By conducting research where the measuring instrument was an interview, we established the characteristics of speech expression in fourth-grade elementary school students. The analysis of the results showed that the students use the repetition, do not show a tendency to enrich their vocabulary and mostly use simpler sentences, and do not have a tendency to use sophisticated vocabulary nor more complex syntax in accordance with their age. It is important to notice the loops of spoken expression in fourth graders in order to influence it's improvement, where the greatest responsibility is on teachers. Teachers must pay attention and work on their own speech expression in order to influence the speech expression of their students. In addition, they should pay attention to the most common shortcomings of students' oral expression and adapt the methods of learning and work during the school hour according to them, for example devoting more time to oral presentations etc.
