Drawing upon sociocultural theory of Vygotsky, the current study aims to investigate the effect of dyadic interaction in mixed and matched level proficiency pairings on comprehension and production of request and apology speech acts. The participants were 125 EFL learners who were randomly assigned to control and experimental (interaction) groups. Based on their scores in the pretest including ...

in this investigation, the effects of enclosure, restal delayed grazing andcontinued grazing treatments on the production rate and vegetation cover were studied.study area was sadrabad pasture. after selecting three bands (1+1+1=3 hectare area) asthree treatments in the restricted and non restricted area, they were transected to threetransects. then plots (1×2m2 ) were selected to measure the p...

the speech is an easily accessible signal which clearly represents the characteristics of larynx and vocal folds. therefore, application of some proper machine learning algorithms on a small part of a recorded speech signal may help in non-invasive diagnosing of vocal fold diseases. since there are some experimental evidences that suggest the existence of chaotic behavior in speech production s...

The issue of whether speech is supported by the same neural substrates as non-speech vocal tract gestures has been contentious. In this fMRI study we tested whether producing non-speech vocal tract gestures in humans shares the same functional neuroanatomy as non-sense speech syllables. Production of non-speech vocal tract gestures, devoid of phonological content but similar to speech in that t...

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...

objectives: speech and language development is one of the main aspects of evolution in humans and is one of the most complex brain functions such that it is referred to as one of the highest cortical functions such as thinking, reading and writing. speech and language disorders are considered as a major public health problem because they cause many secondary complications in the childhood and a...

PURPOSE This review summarizes research on disorders of speech production in Down syndrome (DS) for the purposes of informing clinical services and guiding future research. METHOD Review of the literature was based on searches using MEDLINE, Google Scholar, PsycINFO, and HighWire Press, as well as consideration of reference lists in retrieved documents (including online sources). Search terms...

Traditionally, models of speech comprehension and production do not depend on concepts and processes from the phonological short-term memory (pSTM) literature. Likewise, in working memory research, pSTM is considered to be a language-independent system that facilitates language acquisition rather than speech processing per se. We discuss couplings between pSTM, speech perception and speech prod...
