Perceptual processes mediating recognition, including the recognition of objects and spoken words, is inherently multisensory. This is true in spite of the fact that sensory inputs are segregated in early stages of neuro-sensory encoding. In face-to-face communication, for example, auditory information is processed in the cochlea, encoded in auditory sensory nerve, and processed in lower cortical areas. Eventually, these “sounds” are processed in higher cortical pathways such as the auditory cortex where it is perceived as speech. Likewise, visual information obtained from observing a talker’s articulators is encoded in lower visual pathways. Subsequently, this information undergoes processing in the visual cortex prior to the extraction of articulatory gestures in higher cortical areas associated with speech and language. As language perception unfolds, information garnered from visual articulators interacts with language processing in multiple brain regions. This occurs via visual projections to auditory, language, and multisensory brain regions. The association of auditory and visual speech signals makes the speech signal a highly “configural” percept. An important direction for the field is thus to provide ways to measure the extent to which visual speech information influences auditory processing, and likewise, assess how the unisensory components of the signal combine to form a configural/integrated percept. Numerous behavioral measures such as accuracy (e.g., percent correct, susceptibility to the “McGurk Effect”) and reaction time (RT) have been employed to assess multisensory integration ability in speech perception. On the other hand, neural based measures such as fMRI, EEG and MEG have been employed to examine the locus and or time-course of integration. The purpose of this Research Topic is to find converging behavioral and neural based assessments of audiovisual integration in speech perception. A further aim is to investigate speech recognition ability in normal hearing, hearing-impaired, and aging populations. As such, the purpose is to obtain neural measures from EEG as well as fMRI that shed light on the neural bases of multisensory processes, while connecting them to model based measures of reaction time and accuracy in the behavioral domain. In doing so, we endeavor to gain a more thorough description of the neural bases and mechanisms underlying integration in higher order processes such as speech and language recognition.

Perceptual categorization is fundamental to the brain’s remarkable ability to process large amounts of sensory information and efficiently recognize objects including speech. Perceptual categorization is the neural bridge between lower-level sensory and higher-level language processing. A long line of research on the physical properties of the speech signal as determined by the anatomy and physiology of the speech production apparatus has led to descriptions of the acoustic information that is used in speech recognition (e.g., stop consonants place and manner of articulation, voice onset time, aspiration). Recent research has also considered what visual cues are relevant to visual speech recognition (i.e., the visual counter-parts used in lipreading or audiovisual speech perception). Much of the theoretical work on speech perception was done in the twentieth century without the benefit of neuroimaging technologies and models of neural representation. Recent progress in understanding the functional organization of sensory and association cortices based on advances in neuroimaging presents the possibility of achieving a comprehensive and far reaching account of perception in the service of language. At the level of cell assemblies, research in animals and humans suggests that neurons in the temporal cortex are important for encoding biological categories. On the cellular level, different classes of neurons (interneurons and pyramidal neurons) have been suggested to play differential roles in the neural computations underlying auditory and visual categorization. The moment is ripe for a research topic focused on neural mechanisms mediating the emergence of speech representations (including auditory, visual and even somatosensory based forms). Important progress can be achieved by juxtaposing within the same research topic the knowledge that currently exists, the identified lacunae, and the theories that can support future investigations. This research topic provides a snapshot and platform for discussion of current understanding of neural mechanisms underlying the formation of perceptual categories and their relationship to language from a multidisciplinary and multisensory perspective. It includes contributions (reviews, original research, methodological developments) pertaining to the neural substrates, dynamics, and mechanisms underlying perceptual categorization and their interaction with neural processes governing speech perception.

Speech recognition in ‘adverse conditions’ has been a familiar area of research in computer science, engineering, and hearing sciences for several decades. In contrast, most psycholinguistic theories of speech recognition are built upon evidence gathered from tasks performed by healthy listeners on carefully recorded speech, in a quiet environment, and under conditions of undivided attention. Building upon the momentum initiated by the Psycholinguistic Approaches to Speech Recognition in Adverse Conditions workshop held in Bristol, UK, in 2010, the aim of this volume is to promote a multi-disciplinary, yet unified approach to the perceptual, cognitive, and neuro-physiological mechanisms underpinning the recognition of degraded speech, variable speech, speech experienced under cognitive load, and speech experienced by theoretically relevant populations. This collection opens with a review of the literature and a formal classification of adverse conditions. The research articles then highlight those adverse conditions with the greatest potential for constraining theory, showing that some speech phenomena often believed to be immutable can be affected by noise, surface variations, or attentional set in ways that will force researchers to rethink their theory. This volume is essential for those interested in speech recognition outside laboratory constraints.

"When we speak, we configure the vocal tract which shapes the visible motions of the face and the patterning of the audible speech acoustics. Similarly, we use these visible and audible behaviors to perceive speech. This book showcases a broad range of research investigating how these two types of signals are used in spoken communication, how they interact, and how they can be used to enhance the realistic synthesis and recognition of audible and visible speech. The volume begins by addressing two important questions about human audiovisual performance: how auditory and visual signals combine to access the mental lexicon and where in the brain this and related processes take place. It then turns to the production and perception of multimodal speech and how structures are coordinated within and across the two modalities. Finally, the book presents overviews and recent developments in machine-based speech recognition and synthesis of AV speech"--Provided by publisher.

Fluency is the quintessence of effective reading. To obtain socio-economic success, fluent reading is of primordial importance and reading is considered a crucial marker of an individual’s life course. Approximately 5% of children are affected by developmental dyslexia, exhibiting inaccurate word recognition, spelling, phonological decoding, and most importantly, severely dysfluent reading, which remains as their most characterizing and persistent deficit. Unable to attain society’s literacy demands, individuals with dyslexia are at severe risk for adverse academic, economic, and psychosocial consequences. Recently, it has been posed that the development of automatic letter-speech sound (LSS) integration is critical in the acquisition of fluent reading skills, and in particular that a failure to develop automatic LSS integration results in an impairment of reading fluency. In support, neurocognitive research has suggested that the development of automatized processing of LSS associations is an essential step in the formation of a functional neural network for reading. Furthermore, both neurocognitive and behavioural studies have suggested a less efficient LSS integration in children with dyslexia than in typical readers. Finally, results from intervention studies have suggested that training LSS might be a promising approach to ameliorate dysfluent reading in children with dyslexia. Nonetheless, there is still a considerable gap of knowledge in our understanding of the mechanisms by which learning LSS associations relate to (dys)fluent reading.

Cognitive neuroscience has grown into a rich and complex discipline, some 35 years after the term was coined. Given the great expanse of the field, an inclusive and authoritative resource such as this handbook is needed for examining the current state-of-the-science in cognitive neuroscience. Spread across two volumes, the 59 chapters included in this handbook systemically survey all aspects of cognitive neuroscience, spanning perception, attention, memory, language, emotion, self and social cognition, higher cognitive functions, and clinical applications. Additional chapters cover topics ranging from the use of top-down cognitive processes in visual perception to the representation and recognition of objects and spatial relations; attention and its relationship to action as well as visual motor control; language and related core abilities including semantics, speech perception and production, the distinction between linguistic competence and performance, and the capacity for written language. Special coverage is also given to chapters describing the psychopharmacology of cognition, the theory of mind, the neuroscience underlying the regulation of emotion, and neuropsychological and neuroimaging evidence that supports the special status of self-knowledge in memory. This handbook provides a comprehensive compendium of research on cognitive neuroscience that will be widely accessible to students, researchers, and professionals working in this exciting and growing field.
