Motivation:Conventional fixed expressions
and catchphrases rely on prosody to communicate
systematic functionality, as well as uniqueness
Conclusions:By emphasising the relation between F0 and
periodic energy, periograms can intuitively display different
phonetic realisations of the same phrase in different interactional
settings, while accounting for pervasive syllabic reduction in
naturally occurring speech [6,7].
Periograms of spontaneous speech indicate that tonal events
might not have to be associated to canonical syllables as docking
sites, paving the way for an intonational phonology of
spontaneous speech [8,9].
