This project will benefit the 1 in 20 Australian children who stutter and their families. We will learn for the first time how stuttering impacts on child development in the early school years and document the relationship between stuttering and other childhood conditions. The study will produce much needed information about recovery from stuttering and stuttering persistence. Therefore new knowledge will result to inform the scientific community and provide professionals and families with much needed evidence-based information about stuttering progression. Together this information will inform intervention approaches and help direct resources to those children who need them most. Read moreRead less

The language abilities of young offenders: Missing links in theory and practice.. Young offenders are a complex and challenging population, with high rates of comorbidity between attentional, learning, and behaviour problems. Few workers have, however, considered the underlying language processing and production skills in this population. Available evidence indicates a high level of vulnerability to language disorders in young offenders. These may contribute to poor academic performance and fail ....The language abilities of young offenders: Missing links in theory and practice.. Young offenders are a complex and challenging population, with high rates of comorbidity between attentional, learning, and behaviour problems. Few workers have, however, considered the underlying language processing and production skills in this population. Available evidence indicates a high level of vulnerability to language disorders in young offenders. These may contribute to poor academic performance and failure to develop prosocial skills. This study will explore language competencies and will describe their relationship to social skills, patterns of comorbidity, and type of offence (property Vs violent). Findings will be relevant to theories of juvenile offending and design of prevention/intervention programsRead moreRead less
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
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. 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 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
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
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.
Determinants of Audio-Visual effects in degraded and non-degraded speech. Seeing a speaker's face can affect the perception of their speech in a number of ways. This project proposes a detailed comparison of factors that affect Audio-Visual (AV) facilitation of degraded speech detection and identification. Detection-based tasks should be more sensitive to signal based correlations whereas identification-based effects more sensitive to complementary information. The significance of the current pr ....Determinants of Audio-Visual effects in degraded and non-degraded speech. Seeing a speaker's face can affect the perception of their speech in a number of ways. This project proposes a detailed comparison of factors that affect Audio-Visual (AV) facilitation of degraded speech detection and identification. Detection-based tasks should be more sensitive to signal based correlations whereas identification-based effects more sensitive to complementary information. The significance of the current proposal is that it offers both a strategy and a connected series of experiments for determining key behavioural constraints on AV speech integration. Understanding AV interactions will build links between neurophysiological processes and coherent perception and have important implications for AV application.Read moreRead less
Uptalk in Australian English Intonation. Australian English speakers often use rising instead of falling intonation at the end of sentences which are not questions. This phenomenon of uptalk is one of the unique traits of the Australian English accent. The project will model uptalk by analyzing spoken dialogues from 150 speakers from three major populations, Sydney, Melbourne, and regional Victoria. The intonation patterns of regional and non-Sydney populations have been poorly investigated ....Uptalk in Australian English Intonation. Australian English speakers often use rising instead of falling intonation at the end of sentences which are not questions. This phenomenon of uptalk is one of the unique traits of the Australian English accent. The project will model uptalk by analyzing spoken dialogues from 150 speakers from three major populations, Sydney, Melbourne, and regional Victoria. The intonation patterns of regional and non-Sydney populations have been poorly investigated, so this kind of study is needed to get a more complete understanding of Australian English intonation and the Australian accent. Outcomes will include publications on intonation and laboratory phonology, sociophonetics, and a working model of intonation that can be implemented in speech output systems for Australian English.Read moreRead less
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.
