Abstract
This study investigated how predictability and prosodic phrasing interact in accounting for the variability of syllable duration in Taiwan Southern Min. Speech data were extracted from 8 hours of spontaneous speech. Three predictability measurements were examined: bigram surprisal, bigram informativity, and lexical frequency. Results showed that higher informativity and surprisal led to longer syllables. As for the interaction with prosodic positions, there was a general weakening of predictability effects for syllables closer to the boundary, especially in the pre-boundary position, where pre-boundary lengthening was the strongest. However, the effect of word informativity appeared to be least modulated by this effect of boundary marking. These findings are consistent with a hypothesis that prosodic structure modulates the predictability effects on phonetic variability. The robustness of informativity in predicting syllable duration also suggests a possibility of stored phonetic variants associated with a word's usual contextual predictability.
期刊介绍：
Contemporary research into spoken language employs a wide range of approaches, from instrumental measures to perceptual and neurocognitive measures, to computational models, for investigating the properties and principles of speech in communicative settings across the world’s languages. ''Phonetica'' is an international interdisciplinary forum for phonetic science that covers all aspects of the subject matter, from phonetic and phonological descriptions of segments and prosodies to speech physiology, articulation, acoustics, perception, acquisition, and phonetic variation and change. ''Phonetica'' thus provides a platform for a comprehensive understanding of speaker-hearer interaction across languages and dialects, and of learning contexts throughout the lifespan. Papers published in this journal report expert original work that deals both with theoretical issues and with new empirical data, as well as with innovative methods and applications that will help to advance the field.
