| Research Abstract |
To improve the performance of analyzing foreign language pro-nunciations, structural representation of speech was introduced to the task of scoring the pronunciation, detecting pronunciation errors, and clustering students' pronunciations. The structural representation allows us only to represent the pronunciation only based on sound-to-sound relations. By using the relations as well as absolute sound features, which have been conventionally used, the performance of scoring and error detection was im-proved. High validity of students' clustering was also shown.
