The aim of this paper is to describe the speech therapy procedure in the case of children with cleft lip and palate, with a particular focus on preventive measures. It discusses the elements of the procedure that could significantly influence the effects of the therapy in detail. Improperly selected exercises to train organs of speech or improve breathing will not bring satisfactory effects or can even intensify bad habits. Complying with the recommendations described in this paper is particularly important in the treatment of children with open nasality.
