Natural Semantic Metalanguage (NSM): formalisation, computation, referential semantics. Meaning is what links language with culture, communication and cognition but strangely enough, most linguists do not regard semantics (the systematic study of meaning) as a central part of their discipline. This project pursues basic research in the leading meaning-based theory of language: the natural semantic metalanguage (NSM) theory, which has been originated and developed primarily in Australia.

Meaning is what links language with culture, communication and cognition but strangely enough, most linguists do not regard semantics (the systematic study of meaning) as a central part of their discipline. This project pursues basic research in the leading meaning-based theory of language: the natural semantic metalanguage (NSM) theory, which has been originated and developed primarily in Australia. It aims to make this theory more precise, to work out how it can be used by computers, and to connect it with other, more mathematically inspired approaches to meaning.Read moreRead less
Papuan Descriptive Linguistics of the West Sepik Region. The New Guinea area has an exceptional, but very poorly understood linguistic diversity, over 1000 languages belonging to many unrelated families. This project will fill in gaps through on site fieldwork in Sandaun (West Sepik) Province, linguistically the most genetically diverse and least known province in all of Papua New Guinea. The grammatical descriptions resulting will enrich our understanding of linguistic variation, not only in ....Papuan Descriptive Linguistics of the West Sepik Region.

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? 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.

Ask the Net: Intelligent Natural Language Learning. Natural Language Processing (NLP) has progressed rapidly using corpus-based machine learning techniques. However, corpus development costs cause a ?data bottleneck? which prevents systems from reaching human competence.

Natural Language Processing (NLP) has progressed rapidly using corpus-based machine learning techniques. However, corpus development costs cause a ?data bottleneck? which prevents systems from reaching human competence. This project overcomes the difficulties of creating huge corpora by employing the innate language ability of untrained contributors. We will show how to automatically select and present examples, containing informative linguistic structures, which are most beneficial for training NLP systems. These examples will be analysed by many contributors whose responses will be automatically collated into corpora. Huge corpora are vital to emerging language technologies for managing textual information in the global economy.

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
Language typology and cognitive effects of language learning. This project aims to map, in older adults and preschool-age children, the extent and nature of cognitive benefit from training in a foreign language. Learning a language is recognised to be beneficial in various ways, but this project investigates whether it matters which language one learns. The project will compare the resulting cognitive changes to language learners across different languages to test whether the benefit is uniquely ....Language typology and cognitive effects of language learning. This project aims to map, in older adults and preschool-age children, the extent and nature of cognitive benefit from training in a foreign language. Learning a language is recognised to be beneficial in various ways, but this project investigates whether it matters which language one learns. The project will compare the resulting cognitive changes to language learners across different languages to test whether the benefit is uniquely effective. It will also gauge whether these changes occur when learning is easier in childhood compared to when it is harder later in life. The project findings will inform the development of linguistic, social, and educational programs to optimise cognitive function both for childhood development and healthy ageing, especially in Australia where second language acquisition is lower compared to other countries.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

The project will provide a crucial test of current theories of language processing and linguistic typology via experimental work on the Indigenous language Wubuy, a language that defies the perceived fundamental distinction between words and phrases. This will have significant benefit to Indigenous language maintenance and revitalisation efforts and thus help improve Indigenous education outcomes and reinforce cultural pride.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.

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
