Á¦¸ñ Using Formant Comparison Method to Design a Korean Pronunciation Self-Study System for Chinese Learn







Because of Korean popular spread abroad rapidly through China, Korean language study has been became very popular. However, the pronunciation has many difference between Korean and Chinese. Therefore, the Chinese learners are difficult to study and exercise the Korean pronunciation exactly by themselves. Even if the learner study the Korean with a teacher, the teacher cannot supervise the learner all the time. Formant is an acoustic resonance of the human vocal tract that is able to know the sound production of the speaker. In this paper, using formant comparison method to design a Korean pronunciation self-study system for Chinese learner was presented. Through the developed algorithm, the formants are measured as amplitude peaks in the frequency spectrum of the Chinese leaner¡¯s voice, the results can be explained by a spectrogram and comparison with the standard pronunciation to find the error of pronunciation automatically. The algorithm was designed by a Matlab program and conduct an experiment to test the performance. The experimental results shown the designed algorithm is able to measure the formant of the sound wave accurately, and the Chinese learners can find the reason of the error pronunciation easily by the designed comparison method. In the future, the presented system will be developed for more languages and transplanted to the mobile device.
