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

The network connects leading and emerging researchers across disciplines, exploits previously unrecognised intersections, supports interdisciplinary graduate training and exchanges, provides database storage infrastructure, and consults with industry and government to set, not follow, research agendas. By generating an explosion of new approaches and knowledge, the network will build Australia's reputation as a leader in communication science and technology via advances in automatic speech recognition, distress call monitoring, hearing prostheses, web interfaces, and data retrieval and data mining systems.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
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

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
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
Language processing in children with high functioning autism: Evidence from eye tracking. The language abilities in people with autism predict their response to intervention and their cognitive outcome. Young children with autism with poor language abilities are severely disadvantaged. Yet we understand little about what impedes their language development and their interpretation of what others say. The research findings will make a significant contribution by enriching our understanding of why ....Language processing in children with high functioning autism: Evidence from eye tracking. The language abilities in people with autism predict their response to intervention and their cognitive outcome. Young children with autism with poor language abilities are severely disadvantaged. Yet we understand little about what impedes their language development and their interpretation of what others say. The research findings will make a significant contribution by enriching our understanding of why and how comprehension may go astray, as well as helping us to identify subgroups within the autism population.Read moreRead less
Using written language to probe speech recognition models. Speech recognition models fall into two principal classes, with fundamentally different processing architectures. Feedback models (e.g. TRACE, McClelland & Elman, 1986) allow lexical knowledge to exert top-down control over phonemic analysis. Feedforward models (e.g. Merge, Norris, McQueen & Cutler, 2000) assume that information flow is entirely bottom-up. Our project adopts an innovative approach to testing between these model classe ....Using written language to probe speech recognition models. Speech recognition models fall into two principal classes, with fundamentally different processing architectures. Feedback models (e.g. TRACE, McClelland & Elman, 1986) allow lexical knowledge to exert top-down control over phonemic analysis. Feedforward models (e.g. Merge, Norris, McQueen & Cutler, 2000) assume that information flow is entirely bottom-up. Our project adopts an innovative approach to testing between these model classes, by examining the influence of written-word knowledge on speech perception. To distinguish the models, contrasts must test different processing levels and examine strategy effects. TRACE favors broad effects with limited strategic influence; Merge favors lexical effects that are necessarily sensitive to strategic factorsRead moreRead less

Optical imaging of brain activity: Studies of the neural basis of sensory perception, plasticity and behaviour. Basic to the understanding of the brain is to know how the overall architecture of the nervous system relates to its function. We propose to study this by directly visualising the regions that are functionally active in the living brains of animals, down to resolution limits of less than 100 micrometres.

Basic to the understanding of the brain is to know how the overall architecture of the nervous system relates to its function. We propose to study this by directly visualising the regions that are functionally active in the living brains of animals, down to resolution limits of less than 100 micrometres. Such "optical imaging" will be done by recording light reflected from the surface of the brain, which in turn depends upon activity-dependent intrinsic signals (eg. degree of oxygenation of haemoglobin). These signals will be recorded by a special camera and amplified using the requested system.Read moreRead less
