| Abstract(in English) | A method to automatically assess the pronunciation of Japanese ESL students and identify pronunciation errors most critical to their intelligibility is presented. In an experimental study, we evaluate students intelligibility on a 5-level scale and detect their pronunciation errors using Automatic Speech Recognition. We demonstrate which errors characterize each level of intelligibility. We propose an algorithm based on the statistical distributions of the error rates to assess students intelligibility. A given student's error rates are compared to those of students of the same intelligibility level to determine which errors should be studied in priority. This algorithm was implemented in a pronunciation learning system that diagnoses the student's pronunciation on situational skits and guides the student towards adapted pronunciation drills. Preliminary results on intelligibility estimation confirm the validity of the approach. |
