The article discusses the research on emotional prosody, which refers to the sound properties of vocal expressions that convey both linguistic and paralinguistic information, such as a speaker's intention and emotional state. Despite decades of research, the relationship between acoustic features and emotional states remains unclear. The authors summarize the existing literature, highlight challenges in understanding emotional prosody, and propose directions for future research. They emphasize the importance of emotional prosody in human communication, particularly in psychology, clinical applications, and technology. The study reviews the development of acoustic features used to identify emotional prosody, including quality/spectral features, dynamic/contour features, and other features. It also discusses the role of factors such as speech material, acoustic characteristics, and cultural differences in the mapping between acoustic features and emotions. The authors suggest that future research should focus on improving the accuracy of emotional prosody recognition, considering the complexity of the relationship between acoustic features and emotional states. The article concludes that emotional prosody is a crucial aspect of human communication and that further research is needed to better understand its acoustic properties and their implications in various fields.The article discusses the research on emotional prosody, which refers to the sound properties of vocal expressions that convey both linguistic and paralinguistic information, such as a speaker's intention and emotional state.
