Abstract

The purpose of this study is to examine how
suprasegmental amplitude manipulation on different
linguistic levels (sentence, word, syllable) would
affect perceptual dominance ratings. Six (Canadian)
English speakers produced sentences/paragraphs with
neutral valence. Amplitudes were then manipulated
on three levels: (i) sentence/paragraph (i.e. amplitude
enhancement of entire phrases or paragraphs), (ii)
word (one specific word in focus, realized with
enhanced amplitude), and (iii) syllable (i.e.
increasing/decreasing amplitude differences between
all stressed versus unstressed syllables). 71
participants of an online perception experiment then
rated the stimuli on 4 continuous sliding scales
corresponding to concepts of social and physical
dominance. Results showed that amplitude increases
on sentence level significantly increased dominance
ratings. In contrast, on the syllable level significantly
decreased dominance ratings were observed for
increased amplitude levels. Word level manipulations
and the decreased syllable condition did not have an
effect on ratings
