Abstract: In order to investigate what acoustic features are important to emotional impressions and how those features relate to emotion perception, we interpolate voices from pairs of typical emotions with a morphing method, collect emotion scores on Arousal-Valence space by a listening test, and analyze how acoustic features relate to the evaluations. The results show that Arousal perception can be stably described by merely using fundamental frequency (F0). In contrast, although this research found that F0 and formants can fit Valence scores, how acoustic features correspond to Valence perception vary with different morphing references. Furthermore, the results show that modification rules of different formant components are necessary for the voice conversion system with better Valence control.
