The effects of sentence structure on consonant and vowel articulations. Whilst machine-generated speech is generally of good quality at the level of the single word, it is noticeably less natural-sounding at the level of the sentence. This project examines an important aspect of the naturalness of human speech, namely, the effect that sentence structure has on individual consonants and vowels. A break-down of this naturalness is seen in some speakers who have suffered traumatic brain injury: suc ....The effects of sentence structure on consonant and vowel articulations. Whilst machine-generated speech is generally of good quality at the level of the single word, it is noticeably less natural-sounding at the level of the sentence. This project examines an important aspect of the naturalness of human speech, namely, the effect that sentence structure has on individual consonants and vowels. A break-down of this naturalness is seen in some speakers who have suffered traumatic brain injury: such speakers perform well when asked to utter a short word, but struggle when asked to produce a longer string of sounds. A better understanding of the interaction between speech sounds and sentence structure will lead to improvements in the treatment of speech disorders, and in the quality of human-machine communication.Read moreRead less
Phonological effects on the development of inflectional morphology. This project investigates the mechanisms underlying typically developing children's variable omission of inflectional morphemes (for example, plural, past tense). The results will have significant implications for the evaluation and design of interventions for language-delayed populations where serious problems of communication persist.
How Strict is the Mother Tongue? Using Dialects to Probe Early Speech Perception and Word Recognition. This project will 1)advance knowledge of toddler word representations and their developmental precursors; 2) contribute to theories of phonological vs phonetic properties of spoken language; 3) explain how experience with the ambient language shapes children's phonological and lexical development. Moreover, the findings will 4) offer crucial new insights into sources of developmental disorders ....How Strict is the Mother Tongue?

This project will 1)advance knowledge of toddler word representations and their developmental precursors; 2) contribute to theories of phonological vs phonetic properties of spoken language; 3) explain how experience with the ambient language shapes children's phonological and lexical development. Moreover, the findings will 4) offer crucial new insights into sources of developmental disorders (language delay, dyslexia) leading to improved early diagnosis and treatment; 5) bear on issues of second language learning; and by understanding the process by which young learners handle dialect variability, 6) provide insights into how automatic speech recognition systems can be made more robust to dialectal and foreign accent differences.

Development of second language phonetic and phonological categories. The majority of the world's population speaks two or more languages, yet we know little about how multiple languages are accommodated within a single speaker. Why do children appear to learn a second language 'like a native' but adults invariably develop a clearly perceptible foreign accent? This project investigates a little-known fact - adult second language speakers also 'hear' with a foreign accent. As Australia becomes inc ....Development of second language phonetic and phonological categories. The majority of the world's population speaks two or more languages, yet we know little about how multiple languages are accommodated within a single speaker. Why do children appear to learn a second language 'like a native' but adults invariably develop a clearly perceptible foreign accent? This project investigates a little-known fact - adult second language speakers also 'hear' with a foreign accent. As Australia becomes increasingly multilingual increasing our understanding of the human capacity for language learning would strengthen Australia's social and economic fabric by leading to improved educational practices, work prospects for migrants and, most importantly, understanding between cultures.Read moreRead less
An instrumental investigation of consonant sequences in a northern Australian language. Australian indigenous languages are of great interest, due in part to their unique phonetic structure relative to many other languages of the world. Most advances in speech science and phonetic theory are based on studies of English, or other European languages, yet an important goal of phonetic science is to account for speaking and listening processes that are deemed to be universal. Our proposal seeks ....An instrumental investigation of consonant sequences in a northern Australian language.

Most advances in speech science and phonetic theory are based on studies of English, or other European languages, yet an important goal of phonetic science is to account for speaking and listening processes that are deemed to be universal. Our proposal seeks to address key aspects of current phonetic theory and models of speech sound production, by providing data from an indigenous Australian language.Read moreRead less

Summary
Neural and behavioural evidence for children’s learning of grammatical morphology. Children with various types of language delay have problems learning grammatical structure, leading to communicative breakdown. This project will use brain imaging and behavioural methods to understand better the nature of these problems, leading to more effective intervention, better child health and wellbeing, and improved educational outcomes.
Unveiling the mystery of tone perception: How does native language prosody affect adults' perception of foreign tones? This project provides new knowledge about how humans perceive non-native lexical tone categories. The results of this large-scale cross-language study will indicate how native languages constrain human perception of non-native speech (consonants, vowels, intonation). These data will greatly facilitate the research in second language acquisition and teaching, speech perception mo ....Unveiling the mystery of tone perception: How does native language prosody affect adults' perception of foreign tones? This project provides new knowledge about how humans perceive non-native lexical tone categories. The results of this large-scale cross-language study will indicate how native languages constrain human perception of non-native speech (consonants, vowels, intonation). These data will greatly facilitate the research in second language acquisition and teaching, speech perception modeling including automatic speech recognition with tone languages, human speech processing. The findings will also be useful to clinical speech and hearing research for speech and hearing impaired persons, and commercial applications in foreign language teaching, and computer assisted language learning for language learners.Read moreRead less
Rising Intonation in Australian English. The project will model the intonation of Australian English through an analysis of spoken dialogues from over 200 speakers. The study of the different types of rising intonation across different population groups will advance our knowledge of how Australian English is different from other accents, how it has changed in the last 40 years, and how accent is related to social class in Australia. The outcomes include publications on the theory of intonation, ....Rising Intonation in Australian English.

The study of the different types of rising intonation across different population groups will advance our knowledge of how Australian English is different from other accents, how it has changed in the last 40 years, and how accent is related to social class in Australia. The outcomes include publications on the theory of intonation, accent change, and its relationship to social class as well as a working model of intonation that can be implemented in a system for synthesising Australian English speech.Read moreRead less
Illuminating the Language-specific and Physiological Motor-control Influences on Children's Production of Lexical Stress. Great progress has been made in understanding the production of individual speech sounds but much less is known about the production of prosody. Lexical stress is a type of prosody that reflects the contrast between strong and weak syllables within single words. The ability to achieve this contrastivity shows a protracted developmental trajectory in healthy children and is at ....Illuminating the Language-specific and Physiological Motor-control Influences on Children's Production of Lexical Stress. Great progress has been made in understanding the production of individual speech sounds but much less is known about the production of prosody. Lexical stress is a type of prosody that reflects the contrast between strong and weak syllables within single words. The ability to achieve this contrastivity shows a protracted developmental trajectory in healthy children and is atypical in some children with autism. How these developmental influences relate to language-specific versus physiological motor-control factors is unknown. This project will address this critical research problem via innovative acoustic investigations. Outcomes will trigger the next generation of speech production models with potential for impact in areas like speech pathology.Read moreRead less
The relationship between speech production and perception in Australian language speakers: implications for speech development and learning in Aboriginal children. Chronic ear infection blights the life of at least 50% of Aboriginal Australians. In a vicious cycle that extends from generation to generation, it leads to hearing loss, educational disadvantage, socio-economic disadvantage and environmental depredation, which once again leads to ear (and many other) infections. This is a unique atte ....The relationship between speech production and perception in Australian language speakers: implications for speech development and learning in Aboriginal children. Chronic ear infection blights the life of at least 50% of Aboriginal Australians. In a vicious cycle that extends from generation to generation, it leads to hearing loss, educational disadvantage, socio-economic disadvantage and environmental depredation, which once again leads to ear (and many other) infections. This is a unique attempt by researchers across academic disciplines to study the role of language in educational disadvantage and whether this disadvantage might be made worse for Aboriginal children by the early use of English at school. We ask whether, on purely acoustic or linguistic grounds, communicating in an Aboriginal language might offer improved educational and health outcomes for Aboriginal children in the early years.Read moreRead less
