Acoustic expression of emotions in vocal performance: Vibrato variability in emotional singing styles

[摘要] Opera singers adopt different singing styles to express a wide array of emotions and display acoustic features while the audience judges their emotive capabilities. Despite significant breakthroughs in the synthesis of AI singing technology, the encoding emotional expression remains a topic that needs further discussion. When adopting famous opera arias, the emotions in singing are usually closely related to the lyrics. However, a number of researchers have reported that emotions can be judged by a single note [1]. Furthermore, some studies have proved that singers can perform emotions such as ‘‘Anger, Fear, Joy, and Sadness’’ by virtue of the differences in vibrato.
