A Scale from Frowning to Smiling: Perception and Acoustics of Short Stimuli

Klaus Hartl

University of Munich, Germany

The work presented in this paper deals with the listener's ability to distinguish certain nuances in emotional speech. In the first part of this work a perception experiment is described, where stimuli with a duration of only 500 ms were presented to subjects. These stimuli were rated on a scale reaching from "frowning" to "smiling" in order to get a reference value for each presented stimulus.
   Since the results of the perception experiment were very conclusive, acoustic analysis was performed to explore the acoustic correlates. In the second part the extraction of acoustic features is presented, which not only includes F0, formants and related measurements but also voice source parameters derived from the estimation of a LF-model.
   A high intra-speaker variation and also the inaccurate extraction of parameters make it difficult to find appropriate acoustic correlates.
