Dissertation Abstract:

This dissertation examines how Seoul Korean speakers signal and detect the
Accentual Phrase (AP), which is the word-sized prosodic group, using pitch
and speech timing cues. The focus of the experimental investigation is on
how pitch and timing collaborate or compete with each other. All the
experimental materials used are phonemically identical strings which
contain two APs, and can be phrased in two different ways (e.g. 2+3 or 3+2
syllables).

A series of production and perception experiments demonstrated that, first,
the number of syllables within the AP and the type of AP-initial segment
systematically determined the pitch movement over the larger prosodic unit
(the Intonational Phrase). Second, pitch was foregrounded as a perceptual
cue to the AP when pitch and timing competed in experimental stimuli with
naturally occurring pitch and temporal variations; however, the
contribution of timing was magnified when stimuli had prototypical AP pitch
patterns (with a leap at the AP boundary) and an exaggerated timing cue
(compensatory lengthening). Although listeners' response patterns suggested
evidence of a weak trading relation between the pitch and timing, the
application of the trading relation to the perception of the prosodic
boundary seems to be problematic. In addition, listeners' expectation of
utterance-final lengthening affected their temporal perception.

Accentual Phrasing in Seoul Korean seems to be constrained by general
auditory principles, despite its distinctive aspects such as the lack of
metrical structure and the close relationship between micro- and
macro-melody. The auditory grouping principles based on proximity and
similarity may operate cross-linguistically in general, although speakers
seem to make language -specific adjustments. The implications of the
experimental findings on prosodic typology, shared grouping principles in
speech and non-speech sounds, and the linguistic and functional usage of
prosody are also discussed.
