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? 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 (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
Enhancing language learning via auditory training and parent-infant interaction. This project aims to improve adult language learning. Most adults struggle to pronounce foreign speech, because their native processing skills cannot process foreign sounds. During infancy, native sound perception is tuned through listening to variants of speech sounds while interacting with care-givers. This project aims to show that adults can reprogram their processing skills if placed in the rich environment ava ....Enhancing language learning via auditory training and parent-infant interaction. This project aims to improve adult language learning. Most adults struggle to pronounce foreign speech, because their native processing skills cannot process foreign sounds. During infancy, native sound perception is tuned through listening to variants of speech sounds while interacting with care-givers. This project aims to show that adults can reprogram their processing skills if placed in the rich environment available to infants. Rigorous testing will show whether auditory training improves processing of foreign speech sounds in adults and children and leads to successful understanding and pronunciation of foreign words. This project could benefit many Australian monolingual families who have not fully engaged with neighbouring cultures due to a language barrier.Read moreRead less
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
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
Origins of Phonology and Lexicon: Abstract representations before 6 months. Language is one of the most sophisticated human abilities, yet infants learn it easily. The current view is that the origins of language are abstract representations of consonants and vowels that start to form at 6-10 months. However, recent evidence shows that abstraction begins before 3 months, and that carer-infant conversations are vital to the process. This study involves tracking infants’ behavioural and brain deve ....Origins of Phonology and Lexicon: Abstract representations before 6 months. Language is one of the most sophisticated human abilities, yet infants learn it easily. The current view is that the origins of language are abstract representations of consonants and vowels that start to form at 6-10 months. However, recent evidence shows that abstraction begins before 3 months, and that carer-infant conversations are vital to the process. This study involves tracking infants’ behavioural and brain development from 1 to 18 months and analysing carer-infant speech, to determine how early abstraction supports vocabulary growth, how carer speech assists this process, and what early conditions predict language development, thus benefiting earlier identification of language delay, and saving significantly on later remediation.Read moreRead less

The Big Australian Speech Corpus: An audio-visual speech corpus of Australian English. Contemporary speech science and technology are driven by the availability of large speech corpora. While audio databases exist for languages spoken in America, Europe and Japan, there is currently no large auditory-visual database of spoken language, and certainly not one for Australian English.

Contemporary speech science and technology are driven by the availability of large speech corpora. While audio databases exist for languages spoken in America, Europe and Japan, there is currently no large auditory-visual database of spoken language, and certainly not one for Australian English. Here we will establish the Big Australian Speech Corpus, which will support a speech science research and development using Australian English and facilitate the development of Australian speech technology applications from automatic speech recognition and text-to-speech synthesis used in taxi and other ordering services, to hearing prostheses and talking head aids for learning-impaired children, and a range of security and forensic applications.Read moreRead less
Learning to talk whitefella way. Many Indigenous children speak Aboriginal English or 'Kriol', which often sounds very different to Standard Australian English. Understanding the differences between these languages, and how 'Kriol' affects the learning of English, will help us to better assist Indigenous children to learn English and likely improve their educational outcomes.
Discovering the developmental trajectory of lexical stress production. In English words some syllables are more strongly stressed than others. Most children will learn to emphasise these syllables appropriately but some will not. This project will help to understand the normal development of this vital aspect of speech production and allow more effective assistance to those who experience difficulties.
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.
