The Effect of Lexical Frequency on Tone Production
نویسندگان
چکیده
Previous research has identified robust effects on segmental production of lexical factors like word frequency, predictability or neighborhood density. One question that remains unanswered is whether such lexical effects hold also at the suprasegmental level. This study investigates whether lexical factors such as usage frequency affect tone production in Cantonese. We recorded Cantonese monosyllabic words of high and low usage frequency, controlling for segmental factors. The results show that lexical factors do influence suprasegmental production. Words of the same tone but of different usage frequency differ significantly in pitch height. Low-frequency words are hyperarticulated and produced with relatively higher pitch. The overall tone space of lowfrequency words is more expanded than that of their high-frequency counterparts.

Production of English Lexical Stress by Persian EFL Learners
This study examines the phonetic properties of lexical stress in English produced by Persian speakers learning English as a foreign language. The four most reliable phonetic correlates of English lexical stress, namely fundamental frequency, duration, intensity, and vowel quality were measured across Persian speakers’ production of the stressed and unstressed syllables of five English disyllabi...

The present study was undertaken to investigate the effects of varying frequency patterns (FPs) of words on the productive acquisition of a young EFL learner in a home setting. Target words were presented to the learner using games and role plays. They were subsequently traced for their frequencies in input and output. Eighteen immediate tests and delayed tests were administered to measure the ...

متن کاملThe effect of lexical frequency and Lombard reflex on tone hyperarticulation
Among the many factors that affect phonetic variation, two of them, low word frequency and speech in noise (Lombard speech), are linked to stronger or fuller realizations of segments. Noise and low usage frequency are both factors that may lead to perceptual difficulty suggesting that the strengthening due to these two factors may be related. To understand how these two factors relate to each o...
متن کاملThe Effect of Extensive Reading on Iranian EFL Learners’ Lexical Bundle Performance: a comparative study of adaptive and authentic texts
Formulaic language and sequence as the core characteristic of real-life language and native-like fluency, has been a subject of inquiry in recent decades. The aim of the present study is to investigate the effects of two extensive reading text types, i.e., adaptive and authentic, on Iranian EFL learners’ development of lexical bundles. To this aim, 20 intermediate EFL learners were chosen to pa...
