Evaluation and Education of Standard Chinese Single Vowel Pronunciation Based on Speech Analysis

Abstract

This study analyzed the experimental reports of current or preliminary Chinese teachers attending Hankuk University of Foreign Studies Graduate School of Education to present a standard Chinese vowel pronunciation evaluation and education using speech analysis technology. As a result of the study, it was found that accurate pronunciation diagnosis was possible through the formants table used for vowel speech analysis, and specific and intuitive correction measures that can be applied in the field were needed to lead to pronunciation correction. In other words, in the vowel correction plan, rather than the expression of moving the position of the tongue to high, low, or front and back, it was found that high-operability and efficient guidance such as “Open your mouth wide.” or “Open your mouth small.”, “Pout your lips.” or “Flat your lips.” was needed. Through this study, I felt the need to melt related terminology in the pronunciation curriculum as well as pronunciation evaluation and education using speech analysis technology, and second, I felt the need to study abdominal vowels, consonants, intonation, and strength based on speech analysis technology. In particular, pronunciation evaluation and education based on voice analysis technology will serve as the first button in establishing an automatic pronunciation evaluation system in the future, so more active research should be conducted in this area.
