Abstract
Smiling while talking can be perceived not only
visually but also audibly. Several acoustic-phonetic
properties have been found to cue smiling in the
acoustic signal. The aim of this study was to validate
properties associated with smiled speech using a
natural video corpus. The realisations of
monophthongs of the same words spoken with and
without a visible smile were compared. The results
show a significant increase of intensity (for all
words), of F2 (for words with the round vowel /o:/)
and of F0 (for all words except the backchannel
marker ja) in the smiled condition.
