Research on Emotional Expression of Students in Different School Stages Based on Speech Emotion Recognition

Abstract

From children to teenagers and then to adults, individuals' emotional expression ability has undergone significant changes. From the compulsory education stage to the general senior middle school stage, students' cognitive and emotional needs will change greatly. Students of different school stages show significant differences in their vocal emotional expression, which not only affects their social skills but also has important guiding significance for educational practice. Therefore, this study focuses on the vocal emotional expression of students at different school stages. This study explores the differences in vocal emotional expression among students at different school stages (primary school, junior high school, and senior high school), with a focus on the expression characteristics of different emotional types and the situation of inconsistent internal and external emotions. The research results show that in terms of emotional types, students at different school stages have a relatively high accuracy rate in expressing sadness, while the accuracy rate for expressing anger is the lowest, and the accuracy rate for expressing anger is significantly lower than that for other emotions. In terms of school stages, the overall accuracy of emotional expression among students improves with the increase of school stages, but the differences between school stages are not significant. In the task of expressing inconsistent internal and external emotions, the study found that senior high school students have significantly better emotional conversion ability than primary and junior high school students, indicating that as the school stage increases, students' adaptability in complex emotional expression tasks gradually improves.
