Temporal, Spectral Evidence of Devoiced Vowels in Korean
نویسنده
چکیده
Vowel devoicing is a phenomenon that is reported to occur in many languages such as Japanese, Parisian and Montreal French, Turkish and English. This paper investigates vowel devoicing in Korean. A devoiced vowel does not exhibit characteristic vocal tract resonances, and instead is realized as a long interval of aspiration or frication following consonant release, resulting in non-distinct segment boundaries between devoiced vowels and adjacent voiceless consonants. This paper examines temporal and spectral evidence of devoiced vowels and, among other findings, reveals that in Korean devoiced high vowels are not segmentally deleted but phonetically masked, suggesting that vowel devoicing results from the overlap of glottal gestures. This paper also examines the effect of the preceding consonant place and manner, and the height and front/backness of vowels on devoicing.

Acoustic Evidence for High Vowel Devoicing in Lezgi
This study uses acoustic analysis to determine whether unstressed pretonic high vowels in Lezgi are deleted or devoiced. We argue that the vowel gesture is not deleted, but it is overlapped and consequently devoiced by the preceding [s] gesture. We use spectral analysis to test the increased gestural overlap hypothesis. Three results support this hypothesis and consequently the devoicing interp...
متن کاملThe lingual articulation of devoiced /u/ in Tokyo Japanese
In Tokyo Japanese, /u/ is typically devoiced between two voiceless consonants. Whether the lingual vowel gesture is influenced by devoicing or present at all in devoiced vowels remains an open debate, largely because relevant articulatory data has not been available. We report ElectroMagnetic Articulography (EMA) data that addresses this question. We analyzed both the trajectory of the tongue d...
متن کاملThe Phonetic Realization of Devoiced Vowels in the Southern Ute Language
In this article, we analyze the phonetic realizations of devoiced vowels from 8 fluent speakers of Southern Ute, a severely endangered Southern Numic Uto-Aztecan language spoken in Southwestern Colorado. Devoiced vowels are considered to be an important aspect of the phonology of Southern Ute, yet very little is known about the pronunciation of such segments. Our findings indicate that devoiced...
متن کاملArchitekt or archtekt? perception of devoiced vowels produced by Japanese speakers of German
In Tokyo Japanese, vowel devoicing is a common process leading to the reduction of high, unstressed vowels, mostly when they occur between unvoiced consonants. Native Japanese speakers learning German show a strong tendency to produce these devoiced vowels in the foreign language, too, despite the lack of this regular process in that language, here in German. This study examines the extent to w...
متن کاملAcoustic and articulatory correlates of Japanese devoiced vowels
In Japanese, high vowels may devoice between two unvoiced obstruents (k[u̥]kaku 'division', k[i̥]kaku 'plan'). Recent studies have shown that the devoicing of non-high vowels (k[ḁ]karu 'take', k[e̥]ta 'digit, k[o̥]tae 'answer') may also occur. This paper evaluates the role of vowel duration and vocal folds gestures involved in vowel devoicing in Japanese. An experiment using an electroglottograph (...
