Speech researchers have long been interested in how auditory and visual speech signals are integrated, and the recent work has revived interest in the role of speech production with respect to this process. Here, we discuss these issues from a developmental perspective. Because speech perception abilities typically outstrip speech production abilities in infancy and childhood, it is unclear how...

The study of second langiage (L2) speech production has a long history in second language (SLA) research, both for what it can tell us about the development of the specific skill and how it might illuminate the general processes of SLA. Over time, studies in L2 phonological attainment have become a battleground for perennial issues in SLA research encompassing cognitive, psychological, and soci...

Until recently, research in speech perception and speech production has largely focused on the search for psychological and phonetic evidence of discrete, abstract, context-free symbolic units corresponding to phonological segments or phonemes. Despite this common conceptual goal and intimately related objects of study, however, research in these two domains of speech communication has progress...

BACKGROUND Detailed knowledge of the neurophysiology of speech acquisition is important for understanding the developmental aspects of speech perception and production and for understanding developmental disorders of speech perception and production. METHOD A computer implemented neural model of sensorimotor control of speech production was developed. The model is capable of demonstrating the...

Temporal periodicity is the main physical correlate used experimentally in relating perceived pitch to vocal fold frequency. The accuracy of most measurement methods does not, however, match the pitch difference limens of normal hearing. Our a an im thems The experimental results presented here are concerned with the observations, and resulting understanding, that can be derived when routine an...

DIVA (Directions into Velocities of Articulators) is a mathematical model of the processes behind speech acquisition and production, supposed to achieve a functional representation of areas in the brain that are involved in speech production and speech perception. Introducing cerebellum control mechanism into the model plays a significant role in improving the mechanism of speech acquisition an...

Neurolinguistic investigations support the dissociation between speech production and speech perception in the case of aphasia. This means that an aphasic patient may be able to understand words and sentences while he is not able to produce them or, he may be able to produce certain linguistic forms properly while he is not able to detect the semantics of verbal utterances. Empirical data, howe...

Talkers modify their speech production in noisy environments partly as a reflex but also as an intentional communicative strategy to facilitate the transmission of the speech signal to the interlocutor. Previous studies have shown that talkers can adapt both auditory and visual elements of speech produced in noise. The current study examined whether auditory and visual speech production would b...
