ENGLISH SPEECH THE PLACE OF ARTICULATION OF OET ENGLISH CLASS
Previous studies have reported several aspects of voicing of the stops spoken by both Korean speakers and Native English speakers . Pre voiced, also known as truly voiced stops, is the production of vibration of the vocal cords starting before the release burst. The value of pre voicing is measured in negative values; pre voicing is also known as negative VOT or lead-voicing [4]. Voicing occurring before the release burst at the onset position of a word as a pre voicing and at the final position of a word has been a subject of various studies across different languages including English and Korean. Even within one language, voicing of the voiced stops can display different characteristics according to different regions of the speakers of the same language . Moreover, in regards to the voicing of English stop voicing, comparative studies have been conducted between Native speakers of English and speakers of other languages including Cantonese, Japanese, Korean, Mandarin, Saraiki, Spanish and Taiwanese.ENGLISH SPEECH THE PLACE OF ARTICULATION OF OET ENGLISH CLASS
Previous studies have shown that there are regional differences of the prevoicing of voiced stops of American English . It was also suggested that southern varieties of American English voiced stops are more heavily prevoiced than other varieties of American English . While some studies have reported that no gender related differences were found, others have reported that male speakers’ production have more heavily voiced stops than that of female speakers.
The current study is designed to observe the occurrence of the voicing of the English voiced stops produced by both Korean and Native English speakers, and then to compare those aspects in regards to the place of articulation (bilabial, alveolar, and velar) and the syllabic position of a mono-syllabic word (onset and coda). Acoustic analyses of the voicing of the English stops are expected to show the longer duration of prevoicing in the productions of the Native speakers as the previous studies. Korean-Spoken English Corpus (K-SEC) was used for this particular study.
