Abstract: Objective: To establish an articulation scaling system for Uyghur language, and on the base of which to lay a foundation for articulation treatment of Uyghur cleft palate postoperative patients who suffer from articulation disorders. Methods: Normal Uyghur speech articulation scale was made according to the acoustic characteristics and morphological characteristics of normal Uyghur. The words were read by 31 Uyghur cleft palate postoperative patients and normal Uyghur people. Meanwhile their voices were recorded into the computer. Two judgers scored the articulations of the recordings. An articulation scaling system was finally established taking into consideration both the characteristics of cleft palate speech and features of Uyghur language. Results: Uyghur acoustic features of Uyghur cleft palate patients were summarized, and an articulation scaling system was firstly established. Conclusion: The articulation scaling system laid a theoretical foundation for articulation treatment of Uyghur cleft palate postoperative patients, provided necessary references for speech pathology research, and initiated studies on Uyghur speech pathology.
