This study aims to test a prediction of recent theoretical frameworks in speech motor control: if speech production targets are specified in auditory terms, people with better auditory acuity should have more precise speech targets. To investigate this, we had participants perform speech perception and production tasks in a counterbalanced order. To assess speech perception acuity, we used an a...

The objective of the research in speech communication is to gain an understanding of the processes whereby (a) discrete linguistic entities are encoded into speech by human talkers, and (b) speech signals are decoded into meaningful linguistic units by human listeners. Our general approach is to formulate theories or hypotheses regarding certain aspects of the speech processes, obtain experimen...

Alternative assessment approaches received considerable attention soon after a discontent with traditional, one-shot testing. These approaches, however, have been used only to improve learners’ linguistic ability despite communicative models of language which pointed that knowledge of language also involves pragmatic ability (Bachman, 1990; Bachman & Palmer, 1996). The present study tries to ex...

For 30 male and 30 female talkers, distributions of short-term rms speech levels, relative to the corresponding long-term rms levels, were determined in each of eight 1/3-oct bands for six short-term measurement intervals. Consecutive, Hanning-windowed, 20-ms time records were combined to produce nominal measurement intervals ranging from 20 to 120 ms. For each measurement interval, mean distri...

When we speak, we spontaneously produce gestures (cospeech gestures). Co-speech gestures and speech production are closely interlinked. However, the exact nature of the link is still under debate. To addressed the question that whether co-speech gestures originate from the speech production system or from a system independent of the speech production, the present study examined the relationship...

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 ...
