A Predictive Model of Prosody Through Grammatical Interface: A Computational Approach
This research contributes to our understanding of the interaction between components of linguistic grammar, in demonstrating the dependencies between phonetics, phonology, syntax and semantics in the encoding of prosody. In addition, my work building on a stochastic model of prosody prediction has …

An investigation of the value of auditory training in the education of deaf children
<p>For over a quarter of a century a difference of opinion has existed regarding the relative value of auditory training in the education of the deaf child. The opponents have insisted that in most deaf children there is little or no residual hearing on which to use acoustic stimulation. The …

Exploration of Lip Shape Measures and their Association with Tongue Contact Patterns
A variety of tools and techniques have been developed to measure the movements of the vocal tract, specifically of the tongue and lips. In recent years, computer technology has allowed for extensive exploration of these precise movements and for the development of speech recognition systems. …

Communication and language development in young children: a case-study evaluation of training for early years practitioners
… (DfES 2006), which was designed to support the development of practitioners’ understanding and skills in relation to children’s speech, language and communication. Effective skills in the area of language and communication are considered critical to academic achievement and later life …

Assessing functional links between speech production and perception in multilingual speakers
The relationship between speech production and speech perception capacities is highly debated. The picture is complicated further by studies of second language acquisition, where development of speech perception is not always accompanied by proportional gains in speech production, and vice versa. …

Discovering linguistic structures in speech : models and applications
… to infer linguistic structures from noisy speech streams seems to be an innate human capability. However, reproducing the same ability in machines has remained a challenging task. In this thesis, we address this task, and develop a class of probabilistic models that discover the latent …

Bayesian algorithms for speech enhancement
The portability of modern voice processing devices allows them to be used in environments where background noise conditions can be adverse. Background noise can deteriorate the quality of speech transmitted through such devices, but speech enhancement algorithms can ameliorate this degradation to …

O desenvolvimento da linguagem e pensamento da criança na visão de Piaget e Vygotsky
The steps of development of the childhood arouse interest in the human being. Seeing the behavior of children is a natural thing for humans, also as making comparisons between them and another children. During a long period the development of speech was seen as smartness, as it differentiates a …

The acquisition of Setswana phonology in children aged 3;0 – 6;0 years : a cross-sectional study
This study aimed to describe the typical development of speech in first language Setswana speaking children. Thirty-six children, aged 3;0 – 6;0 years, attending preschools in Hebron in the North-West Province of South Africa, participated in the study. The objectives of the study were documenting …

The Role of DNA Methylation in Defining the Vocal Learning Transcriptome of the Zebra Finch
… complex behavior which is a critical component of human spoken language acquisition. It is convergent across several independent lineages of birds and mammals, including songbirds and humans. The development of speech and song production in humans and songbirds is strikingly similar, though the …

Formulaic language in speech fluency development in English as a second language
This thesis is an investigation of the role of formulaic language in second language (L2) speech fluency development, within a cognitive and information processing framework. Fluency has been studied and defined in terms of temporal variables of speech such as rate of speech, pause frequency and …

Neural Enhancement Strategies for Robust Speech Processing
In real-world scenarios, speech signals are often contaminated with environmental noises, and reverberation, which degrades speech quality and intelligibility. Lately, the development of deep learning algorithms has marked milestones in speech- based research fields e.g. speech recognition, spoken …

Speech recognition with probabilistic transcriptions and end-to-end systems using deep learning
… we develop deep learning models in automatic speech recognition (ASR) for two contrasting tasks characterized by the amounts of labeled data available for training. In the first half, we deal with scenarios when there are limited or no labeled data for training ASR systems. This situation is …

Gibt es Zusammenhänge zwischen einer expressiven Sprachentwicklungsstörung und einem zentro-temporalen Sharp-Wave-Fokus (Rolando-Fokus) mit der weiteren Entwicklung?
Die Arbeit befaßt sich im Rahmen einer klinischen Studie mit der weiteren Entwicklung von Kindern, bei denen im Kindergartenalter eine expressive Sprachentwicklungsstörung diagnostiziert wurde, und Kindern mit einem zentro- temporalen Sharp- wave- fokus (Rolando- Fokus)im EEG. Anhand …

Neural Time Alignment for End-to-End Automatic Speech Recognition Systems
Automatic Speech Recognition (ASR) is an important component for machines to interact with humans. With the development of deep learning, ASR systems can obtain very low error rates when there is a lot of training data available. Apart from the recognised text, it is also important to determine …

Temporal and Aerodynamic Aspects of Velopharyngeal Coarticulation: Effects of Age, Gender and Vowel Height
<p>Previous studies on the normal patterns of velopharyngeal coarticulation did not provide a multidimensional description of the phenomenon. The primary objective of this study was to determine the effects of age, gender and vowel height on the temporal and aerodynamic aspects of nasal airflow …
