Abstract:
This paper explores how the acoustic characteristics of the
voice signal affect. It considers the proposition that the cueing
of affect relies on variations in voice source parameters (includ-
ing f0) that involve both global, uniform shifts across an utter-
ance, and local, within-utterance changes, at prosodically rele-
vant points. To test this, a perception test was conducted with
stimuli where modifications were made to voice source param-
eters of a synthesised baseline utterance, to target angry and sad
renditions. The baseline utterance was generated with the
ABAIR Irish TTS system, for one male and one female voice.
The voice parameter manipulations drew on earlier production
and perception experiments, and involved three stimulus series:
those with global, local and a combination of global and local
adjustments. 65 listeners judged the stimuli as one of the fol-
lowing: angry, interested, no emotion, relaxed and sad, and in-
dicated how strongly any affect was perceived. Results broadly
support the initial proposition, in that the most effective signal-
ling of both angry and sad affect tended to involve those stimuli
which combined global and local adjustments. However, results
for stimuli targeting angry were often judged as interested, in-
dicating that the negative valence is not consistently cued by the
manipulations in these stimuli.
