It addresses the low precision of existing methods and the time-consuming nature of compiling training data for regression analysis-based estimation methods by language teachers. Our approach employs acoustic-phonetic features extracted using an acoustic-phonetic analysis tool as explanatory variables for regression. We anticipate that integrating these features will enhance estimation precision and reduce data compilation costs. In our experiment, the estimation method incorporating acoustic-phonetic features exhibited a statistically significant improvement over the previous methods.
