Speech therapy techniques that include increasing loudness, tone (e.g., open mouth) were performed during therapy sessions. Furthermore, auditory and visual stimulation was used to improving self-monitoring of the other prosodic features.Results: After ten therapy sessions, improvement of the all measure of interest was indicated on the visual analog scale. Generalization and maintenance was assessed by parents. Moreover, the patients performed self-assessment using equal scale.Conclusion: present study recommends a useful informal evaluation of prosody for clinical purposes.
