Simulated Emotions: an Acoustic Study of Voice and Perturbation Measures

Sandra P. Whiteside

University of Sheffield, UK

This brief study presents a set of acoustic correlates for a number of vocal emotions simulated by two actors. Five short sentences were used in the simulations. The emotions simulated were neutral, cold anger, hot anger, happiness, sadness, interest and elation. The seventy sentences were digitised and a number of acoustic analyses were carried out, which included a number of perturbation measures. The acoustic parameters investigated were: i) mean overall fundamental frequency (Hz); ii) overall mean energy (dB); iii) overall mean standard deviation of energy (dB); iv) mean overall jitter (%); and v) mean overall shimmer (dB). These acoustic parameters were used to profile the vocal emotions. Results showed that the actors displayed similarities in their acoustic profiles for some emotions like anger and sadness, for example. The results are presented and discussed in brief.
