The aim of the paper is to describe the case study of two twin sisters with speech delays
based on the observations and experiments conducted in the form of the prepared
tasks. The author focuses on the children’s interaction skills and characterizes their
speech taking into consideration the speech quality, quantity as well as the problems encountered
by the children in the process of communication. The study reveals the level
of communicative competence represented by the girls, as well as their sociolinguistic
skills. The article finally attempts to define the concept of “readiness to communicate”.
