Phonetics and Phonology
We investigate speech production, speech perception, and phonological organization in human language. We are interested in capturing phonetic and phonological phenomena and processing in adults, during the development of a first or second language, and in terms of the change that can occur in a speech community. We house and use a range of phonetic equipment to tackle our research questions, including -for perception- eye-tracking, and -for production- electromagnetic articulography (EMA), ultrasound, magnetic resonance imaging (MRI), electroglottography (EGG), and electropalatography (EPG).
Solving the puzzle of complex speech sounds
Speech sounds that fall into the 'l' and 'r' family of consonants ('liquids') are amongst the most difficult to master, both for children and for second language learners. Liquids are complex consonants, requiring finely tuned, and language-specific, coordination of articulatory gestures, but the details of this complexity remain poorly understood. Using state-of-the-art articulatory methods, we are examining liquid production and perception in four typologically-distinct languages, to shed more light on the phonological properties of this class of sounds.

Kaytetye and prosodic theory
We are examining the phonological structure of the Australian language Kaytetye, a member of the Arandic language family. Arandic languages have previously been analyzed as having unusual (VC) syllable structures, raising important questions for phonological theory. Through careful documentation and phonetic analysis of Kaytetye word and sentence structure, we aim to shed more light on its phonological organization, and implications for general theories of phonology and universals in language.

Sociophonetic effects during bilingual speech perception
Every time we say something, the speech signal carries two different types of information: linguistic and indexical. The linguistic information conveys the meaning of the message ("what was said"), while the indexical information provides details about the speaker ("who said it"). Indexical/sociophonetic information includes the speaker's age, sex, social class, regional and ethnic background, etc. Results from our psycholinguistic experiments suggest that sociophonetic information is simultaneously activated in a bilingual's two languages during speech perception. In particular, we investigate the activation of ethnicity in Maori-English bilingual New Zealanders, and the activation of speaker sex - and its effect on the processing of grammatical gender - in Italian-English bilinguals living in Australia. This parallel activation has implications for models of the bilingual cognitive architecture, which need to take indexical information into account. Key contact: Anita Szakay.
Infant-directed speech is the register that almost all caregivers cross-linguistically automatically adopt when speaking to young infants and children. Our research is aimed at better understanding the diversity as well as the consistency in the phonetic characteristics of infant-directed speech across languages (e.g., Nepali or Dutch rather than English) and across speakers (e.g., fathers rather than mothers). Our collaborations with child development experts across disciplines highlight the role that infant-directed speech can play in the development of the parent-infant bond and the early stages of healthy emotional development.

The acoustics of suprasegmental variation in dialects of English
Speakers of different dialects sound different. Often this is due to segmental variation, i.e. differences in the pronunciation of particular vowels and consonants. We are investigating how speakers of different ethnic varieties of English use suprasegmentals such as speech rhythm, voice quality, and pitch. Our research draws on data from Maori English in New Zealand, Multicultural London in English in the UK, and Lebanese English in Australia. Through production and perception experiments we examine how speakers index their ethnic identity with regard to prosody, and whether listeners can rely on suprasegmental cues to correctly identify a speaker's ethnicity.

Multicultural Australian English: The new voice of Sydney
Australia is one of the most ethnically diverse countries in the world. Yet the complex relationship between speech production and cultural diversity is largely unknown in 21st century multicultural Australia. This project aims to generate an integrated and inclusive model of Australian English, through meticulous phonetic analysis of spoken language used by Sydney adolescents from a range of ethnic backgrounds. The history of excellence in Australian English phonetic studies and state-of-the-art facilities make Macquarie University the optimal location for this research. Project outcomes are expected to inform sociophonetic theories of variation, ethnicity, and identity, and provide a framework for supporting sociocultural cohesion in Australia.

The Australian Voices project aims to provide a comprehensive analysis of phonetics and phonology of English in Australian to explore aspects of origins, evolution and variation. We aim to investigate the nature of the Australian accent today and how has it evolved in response to the rapidly changing society in which we live. Unprecedented cultural change has led to increased linguistic variation in the community necessitating a reevaluation of ideas about Australian English and its various forms. In particular, we aim to advance our understanding of the wide range of ethnocultural and indigenous varieties and to provide a detailed account of social and regional variation. The proportion of the Australian population born overseas is currently at its highest level in 120 years so it is timely to examine how the accent originated, how it has evolved, and in particular, to consider the impact of sociocultural variation on language change.
