This paper considers the problem of pronunciation of explosive consonants in the pronunciation by children from multicultural Russian-Korean Families. An experiment was conducted to identify the acoustic variations in the pronunciation by children of Korean explosive consonants. In the first stage, a computer program Praat 5.3.48 recorded Russian explosive consonants pronounced by native speakers of Russian, Mother of children.
