Abstract
Experience with native-language prosody encourages language-specific strategies for speech
segmentation. Conflicting findings from previous research suggest that these strategies may not be
abstracted away from the acoustic manifestation of prosodic features in the native speech. Using
the artificial language learning paradigm, the current study explores this possibility in connection
with listeners of a lexical tone language called Taiwanese Southern Min (TSM). In TSM, the only
rising lexical tone occurs almost only on the final syllable of the language’s tone sandhi domain and is
phonetically associated with final lengthening. Based on these observations, Experiment I examined
what constituted a sufficient finality cue for use by TSM listeners to support segmentation: (a) final
fundamental frequency (F0) rise only; or (b) final F0 rise conjoined with final lengthening. The results
showed that segmentation was inhibited by the former cue but facilitated by the latter. Experiment
II showed that the facilitation cannot be attributed entirely to final lengthening, as a null effect was
found when final lengthening was the sole prosodic cue to segmentation. It is thus assumed that
acoustic details as fine-grained as the lengthening of the rising tone are involved in the modulation of
the segmentation strategy whereby TSM listeners perceive F0 rise as signaling finality. The inhibitory
effect of final F0 rise alone found in Experiment I motivated Experiment III, which revealed that initial
F0 rise in the absence of lengthening cues improved TSM listeners’ segmentation. It is speculated
that such use of initial F0 rise might reflect a cross-linguistic segmentation solution.
