Percentage of Dysfluent syllables. Timepoint: The baseline session, immediately before and after the intervention, in all intervention sessions (5 sessions), at the end of the first and sixth weeks after the intervention. Method of measurement: For this purpose, sample reading and conversation of the cases at each of the results evaluation points (baseline session, immediately before and after the intervention, in all the intervention sessions (5 sessions) before and after the therapy assignments and at the end of the first and sixth weeks after the intervention) is recorded. The first 2 minutes of each of the recorded samples are used to check the percentage of non-syllabic syllables (DS). (In these 2 minutes, the reference must have produced at least 200 floods). Also, the topic of conversations and reading text will be new in all assessment and treatment sessions, and no repeated samples will be recorded (standard Persian language texts will be used, including the Rainbow text).
