Abstract

Using electropalatographic (EPG) data, we study the coarticulatory effect of intervocalic contexts on the Persian coronal stops [t] and [d]. The EPG patterns demonstrate that [d] is produced in a more anterior place than [t], proving the former to be a dentialveolar consonant and the latter to be an alveolar one. The coarticulation index (CI) is calculated for each consonant flanked by the same vowels. The results obtained show that there is no significant difference between [t] and [d], in terms of coarticulation; however, based on the data we have, we can say that [t] is more resistant to coarticulatory effect than [d]. This result is in agreement with previous investigations which propose that laminals show stronger coarticulation resistance than apicals.

Highlights

Phoneticians and phonologists use place of articulation as one of the most important parameters when they describe segments
Bladon and Al-Bamerni (1976) – the first scholars who originally proposed Coarticulatory Resistance (CR) – postulated that a numerical CR value can be designated to segments and their extrinsic allophones and this CR value can be used in the speech production mechanism to plan the coarticulatory directionality and magnitude for articulators
Since there was a noticeable difference between the coarticulation index values of [t] and [d], we examined the CI values of [t] and [d] in each intervocalic context separately and conducted an independent sample t-test to compare the CI values for them

Summary

Introduction

Phoneticians and phonologists use place of articulation as one of the most important parameters when they describe segments. The phonetic representation of a phoneme is not always the same and it may vary according to the adjacent segments or its position in the syllable. This mostly occurs because of the overlapping gestures of the two neighboring segments. Bladon and Al-Bamerni (1976) – the first scholars who originally proposed Coarticulatory Resistance (CR) – postulated that a numerical CR value can be designated to segments and their extrinsic allophones and this CR value can be used in the speech production mechanism to plan the coarticulatory directionality and magnitude for articulators Some are more resistant.
