This paper examines, analyzes, and synthesizes literature on VOT production and perception in the context of Motor Theory of speech perception. Specifically, positive and negative evidences from speech production and perception, language acquisition, and evidence of dissociation from speech disorders of VOT are reviewed in the light of the Necessity Condition versus a weaker version of motor th...

Perception results are presented that address the role of Lombard speech in auditory and audiovisual speech perception. Basically, visual enhancement neutralizes the advantage of Lombard speech observed for auditory perception. It remains an open question whether or not Lombard speech is preferable for perception studies of speech in noise.

It has been found that auditory-visual speech perception differs over languages, particularly between English and Japanese speakers. This difference emerges due to increased use of visual information by English speakers between 6 and 8 years [14]. This study investigates the linguistic factors that may cause changes in auditory-visual speech perception development. Children aged between 5 and 8...

background and aim: there is a controversy about cochlear implant usefulness for users since they do not develop speech and language with equal quality. many researchers by controlling demographic and medical variables in this population suggested the contribution of neuro­cognitive factors such as working memory to this variation. the aim of this study was to com­pare working memory capacity b...

Much crosslinguistic research exists on the production and perception of voice onset time (VOT). However, most research on the perception of VOT uses synthetic stimuli instead of natural speech stimuli. Effects of synthetic speech on the perception of VOT are not known, but more research needs to be done to see if there are differences between perception using synthetic speech and perception us...

Research into how speech production and perception are related has a long history. Proponents of the motor theory of speech perception argued in the sixties that speech sounds are perceived in terms of the articulatory features or gestures required to produce those sounds (Liberman et al., 1967; Liberman, 1996). The prediction was that infants, who do not yet produce speech sounds, would have d...

For both adults and children, acoustic context plays an important role in speech perception. For adults, both speech and nonspeech acoustic contexts influence perception of subsequent speech items, consistent with the argument that effects of context are due to domain-general auditory processes. However, prior research examining the effects of context on children's speech perception have focuse...

OBJECTIVE This study aimed to evaluate the long-term speech perception and speech intelligibility of congenitally and prelingually deaf children after cochlear implantation. It was a longitudinal study following 63 congenitally or prelingually deaf children up to 5 years after implantation. They each received a nucleus multichannel cochlear implant before they were 10 years old. METHODS Perce...

The limitation in performance of current speech synthesis and speech recognition systems may result from the fact that these systems are not designed with respect to the human neural processes of speech production and perception. A neurocomputational model of speech production and perception is introduced which is organized with respect to human neural processes of speech production and percept...
