본 연구는 Praat 소프트웨어 프로그램을 이용하여 영어이중모음 /eɪ/ 와 /aɪ/, 그리고 영어전설저모음 /æ/의 발음 길이에 관해 한국인 피 실험자와 원어민 피 실험자를 대상으로 그 차이를 비교분석해보고자 한 연구이다. 이 연구를 위해서 영어문장이 발화되고 녹음되었으며, 피 실험자는 한국인과 원어민 각각 6명씩 참가하였으며, 모두 여성이었고 나이는 23세에서 35세에 위치하고 있다. 음향특질중 하나인 길이측정을 위해서 Praat소프트웨어 프로그램을 활용하였으며, 그 결과를 통계 처리하였다. 실험결과 /eɪ/ 와 /aɪ/에서는 한국인들이 더 길게 발음하였지만 그 차이가 통계상 유의미한 수준은 아니었다. 그러나 /æ/의 발음에서는 한국인들의 발음 길이가 원어민에 비해 훨씬 짧았으며, 그 차이도 통계상 유의미한 수준으로 나타났다.

The purpose of this experimental study is to investigate and compare the vowel lengths of the English diphthongs, /eɪ/ and /aɪ/, and the front low vowel /æ/ among English-speaking natives with Korean college students using the Praat software program. To do this English sentences were uttered and recorded by twelve subjects, six Korean subjects and six English-speaking native subjects. All the subjects are female and their age ranges from 23 to 35. Acoustic features(duration) were measured from a sound spectrogram with the help of the Praat software program and analyzed through statistical analysis. Results showed that the vowel lengths of the English diphthongs and the front low vowel between native English speakers and Korean collegians were different. In the pronunciation of the diphthongs /eɪ/ and /aɪ/, Korean subjects pronounced longer than native subjects did, but the difference was not significant. However, in the pronunciation of the English front low vowel /æ/, native subjects pronounced significantly longer than Korean subjects did. From the data of the overall sum of words and vowels between the two subject groups, we were able to find out that the differences of lengths of both the three words and the two diphthongs /eɪ/ and /aɪ/ were not significant, but those of /æ/ were significant.

가설 설정
According to the study, stressed vowels are shorter before voiceless consonants than before voiced. In addition to that, the study argued that stressed vowels are shorter before an unstressed syllable in a bisyllabic word than in a monosyllabic word. Dennis H.
제안 방법
As the three words, vacation, buy, and camera, have /eɪ/, /aɪ/, and /æ/ respectively in their stressed syllable, I could measure both the vowel lengths of /eɪ/, /aɪ/, and /æ/ and the three words simultaneously. After measuring the lengths, I analyzed the data statistically and tried to find out the difference of vowel lengths and vowel ratio between the two subject groups.
Instead of using this kind of subjective opinion, I will try to investigate the improvement of Korean students' pronunciation features based on the results of the experiment of this study, which could be considered objective judgment.
As the class is required for all the students, they were familiar with the textbook. The main reason I selected this book was that in this dialogue I could find the three words, vacation, buy, and camera. These three words have two English diphthongs, /eɪ/ and /aɪ/, and an English front low vowel /æ/ respectively, all of which are apt to be pronounced differently by Koreans and English-speaking natives especially in vowel lengths.
This study was done to investigate the lengths of the English diphthongs, /eɪ/ and /aɪ/, and the front low vowel /æ/ between English-speaking natives and Korean college students through experiment, the result of which could be used in teaching English pronunciation in the classroom.
대상 데이터
12 females were chosen to participate in this experiment, acting as subjects: 6 Korean female students from Namseoul University and 6 English-speaking female natives from Suwon Global Village. The six Namseoul University students have the experience of having studied abroad for more than six months in the U.
For this experiment, conversation dialogues in World English page 137 were used, which is now being used as the everyday conversation textbook for Namseoul University freshmen. As the class is required for all the students, they were familiar with the textbook.
In addition to this, the lengths of Korean students' pronunciation of the English diphthongs /eɪ/ and /aɪ/ will be investigated. To do this, I selected English test sentences from the page 137 of World English, which is being used as a textbook for Namseoul University freshmen. The three words used in the experiment are vacation, buy, and camera, which include two English diphthongs /eɪ/ and /aɪ/ and front low vowel /æ/ respectively in the stressed syllable.
성능/효과
They also explained that their study showed that the distinction between short and long vowels emerged less consistently in sentential context than in isolation. They concluded that using the data the vowel length distinction is being lost in Korean and is no longer a productive contrast. Dennis H.
