The speech intervention provides individual laboratories in which the speech therapist, through phonetic exercises, teaches the pupil to understand and deliver oral messages. During each session, each child is encouraged to learn how to clearly express his thoughts and emotions.

Throughout the years of schooling, the student is subjected to individual and group speech therapy in which he/she can learn initially to deliver voice and words, and then to express himself with words, to communicate, to understand oral messages and to transmit them.
