In order to investigate objective methods for measuring speech intelligibility, the reliability and validity of the Conversational Intelligibility Test(CIT), frequently used by speech-language-hearing therapists, were examined. The rating data of speech intelligibility obtained by CIT were compared to the results by equal-appearing interval scaling. The intelligibility of 19 glossectomized patients were evaluated by three listeners: listeners experienced and inexperienced with speech disorders of glossectomized patients, and undergraduate students in the Department of Communication Disorders. The intelligibility obtained by CIT was closely related to the results of the equal-appearing interval scaling, and the interjudge reliability was high for the inexperienced listeners and undergraduate students. These results suggest that CIT is a valid method for measuring conversational intelligibility.
