What realization suggests that mastery of fundamental speech structure is a prerequisite invention for high-performing SER?

Answer

Emotion is often an overlay on top of fundamental speech structure

The success seen in modern Speech Emotion Recognition (SER) systems, particularly those utilizing representation learning derived from self-supervised pre-training, points toward a crucial realization regarding the nature of emotion in speech. This insight posits that emotional expression does not create speech from scratch; rather, emotion is typically superimposed or layered upon the fundamental, inherent structure of speech itself—the baseline acoustic characteristics that define a person speaking a language. Because this foundational structure (covering basic articulation, speaker characteristics, and phonetics) must be mastered before deviations caused by emotion can be accurately isolated and classified, leveraging representations learned from general speech processing proves a superior starting point. Therefore, the true prerequisite invention is not just the recognition algorithm, but the mastery of the base speech structure itself.
