This project characterises variability in its chosen domain (phonology, phonetics, syllabic structure) and contributes models which harness variability to identify linguistic structure in phonetic data. The linguistic organization in focus is that of syllables. Syllables are fundamental units of spoken language, mediating between lower-level properties of individual sounds and higher prosody. Recent work indicates that stability patterns of certain intervals, defined over sequences of consonants and vowels, are the phonetic (physical) correlates of distinct syllabic structures. This project examines how consistently interval-based phonetic measures express differences between distinct syllabic structures. We do so by considering the effects of variability in the same syllabic organizations across languages as well as the effect of variability on different syllabic organizations within the same language. Finally, we extend current computational modelling methods for the identification of syllabic structure in phonetic data by endowing them with information about how variability in a number of different factors influences interval-based phonetic measures of syllabic organizations.
