ABSTRACT
Objective:To apply electropalatography(EPG) in speech training for the patients with misarticulations caused by abnormal palatolingual contact, such as palatalized misarticulation(PM) and lateral misarticulation(LM) because of cleft lip and palate. Methods: Four patients with cleft lip and palate averagely aged 12.5 years old were enrolled in this study. PM was found in all the patients with or without LM. Misarticulations of these patients were corrected by visual feedback of EPG in speech training. Speech intelligibility and electropalatogram before and after therapy were compared. Results: It was convenient for the patients to check their pronaciation by the visual feedback of EPG.Their speech intelligibility was improved and palatolingual contact were more anterior after speech training. Conclusion: EPG is a valuable instrument in speech training for patients with misarticulation
