Book Description
Speech perception is dependent upon the ability to map the sensory features of a speech signal onto the perceptual features which make up language (i.e., phonemes). A great deal of research over the past six decades has focused on how variability across talkers influences speech processing. Listeners are required to normalize the acoustic variability across talkers by continuously updating the mapping from the acoustic signal to phonetic representations. As such, processing speech from multiple talkers is cognitively more demanding than listening to a single talker. This processing cost appears to reflect, in part, the influence of listeners’ expectations that speech is coming from multiple sources (talkers). It remains unclear whether talker normalization effects are present in individuals with autism spectrum disorder (ASD), given broad differences in social and sensory processing. The present study examined talker normalization and effects of talker expectation in adolescents with ASD and typical development. Participants were asked to respond to target words embedded in a stream of speech; the pitch of the talkers (F0) varied in half of trials. Furthermore, half of participants were told that this variability was due to fluctuations in a single talker’s speech, while the other half were told that the speech was variable because it was produced by two talkers. Results indicated that participants with ASD were significantly slower to respond under conditions of acoustic variability, while typically developing participants were not. Furthermore, the degree to which participants with ASD were influenced by the variability was significantly correlated with parent-reported sensory atypicality. This relationship was not moderated by ASD symptom severity. Neither diagnostic group was influenced by the manipulation of expectations. Overall, these results suggest that sensory differences present in ASD may account in part for communication difficulties.

Book Description
Early Word Learning explores the processes leading to a young child learning words and their meanings. Word learning is here understood as the outcome of overlapping and interacting processes, starting with an infant’s learning of native speech sounds to segmenting proto-words from fluent speech, mapping individual words to meanings in the face of natural variability and uncertainty, and developing a structured mental lexicon. Experts in the field review the development of early lexical acquisition from empirical, computational and theoretical perspectives to examine the development of skilled word learning as the outcome of a process that begins even before birth and spans the first two years of life. Drawing on cutting-edge research in infant eye-tracking, neuroimaging techniques and computational modelling, this book surveys the field covering both established results and the most recent advances in word learning research. Featuring chapters from international experts whose research approaches the topic from these diverse perspectives using different methodologies, this book provides a comprehensive yet coherent and unified representation of early word learning. It will be invaluable for both undergraduate and postgraduate courses in early language development as well as being of interest to researchers interested in lexical development.

Book Description
The idea that speech is a dynamic process is a tautology: whether from the standpoint of the talker, the listener, or the engineer, speech is an action, a sound, or a signal continuously changing in time. Yet, because phonetics and speech science are offspring of classical phonology, speech has been viewed as a sequence of discrete events-positions of the articulatory apparatus, waveform segments, and phonemes. Although this perspective has been mockingly referred to as "beads on a string", from the time of Henry Sweet's 19th century treatise almost up to our days specialists of speech science and speech technology have continued to conceptualize the speech signal as a sequence of static states interleaved with transitional elements reflecting the quasi-continuous nature of vocal production. This book, a collection of papers of which each looks at speech as a dynamic process and highlights one of its particularities, is dedicated to the memory of Ludmilla Andreevna Chistovich. At the outset, it was planned to be a Chistovich festschrift but, sadly, she passed away a few months before the book went to press. The 24 chapters of this volume testify to the enormous influence that she and her colleagues have had over the four decades since the publication of their 1965 monograph.

Book Description
In this book, some of today’s leading neurolinguists and psycholinguists provide insight into the nature of phonological processing using behavioural measures, computational modeling, EEG and fMRI. The essays cover a range of topics including categorization, acoustic variability and invariance, underspecification, talker-specificity and machine learning, focusing on the acoustics, perception, acquisition and neural representation of speech.
