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.
