Emotion is encoded in the voice at the acoustic level — in pitch variation, energy distribution, timing patterns, and spectral dynamics. The EmotionalEngine analyzes these correlates to classify vocals into eight primary emotional states.
Confident, vulnerable, aggressive, euphoric, melancholic, neutral, tense, and transcendent. Each class has distinct acoustic signatures and corresponding processing implications — a vulnerable vocal needs space and air, an aggressive vocal needs presence and bite.
A vulnerable vocal needs space and air. An aggressive vocal needs presence and bite. These are not style preferences — they are acoustic requirements.
