Characterisation of Stop Consonants in Asian Languages: A Multilingual Study of Unreleased Final Stops - Naver Labs Europe

Final stops are often performed without an audible release burst in many Asian languages, whatever their linguistic families. This work proposes to characterize, from the aerodynamic and glottographic points of view, the final stops / p t k / in two tonal vs. non-tonal Asian languages (Vietnamese and Korean). This paper deals with the study of glottal behavior (the opening and the closing of the vocal folds, the vertical position of the larynx) in synchronization with the measurements of airflow (oral and nasal) during the phases of consonant realization. The results show that (1) there is no nasal release after the consonant closure; (2) the larynx systematically lowers during the closure phase. This realization “strategy” is in line with our hypothesis that the intra-oral pressure drop, characteristic of not releasing, is not due to a possible nasal leak but to the larynx decrease, causing the burst loss of these final stop consonants.
