It is well known that Japanese prosodic structure assumes mora below the syllable tier. Syllables with V or CV structure are counted as having one morn whereas those with coda consonants /-pp, -tt, -kk, -ss, -N/ or long vowels are counted as having two morns in Japanese. This study measured the acoustic duration of these special moras ('tokusyuhaku') produced by Tokyo dialect speakers to see if they are isochronic with V or CV. It also examined the production of Korean(Seoul/Kyungsang dialect) and Chinese native speakers loaming Japanese as a second language to examine how the learners' first language influence their second language. Finally, it examined how speakers of the Akita dialect, which is blown as a syllabeme dialect in Japanese, produced them. The results showed that intra-speaker variation as well as inter-speaker variation was observed in the production by Akita dialect speakers. Production of native speakers of Chinese and Kyungsang dialect of Korean -- which have vowel length contrast in their phonological systems -- showed a similar result to Tokyo dialect speakers, which implies the influence of the learners' first language on the acquisition of the second language.

The results of this thesis show that Seoul dialect speakers neutralized /$\varepsilon$/ and /e/ to /E/ about 80％ and the old aged generations pronounced /ㅐ/ and /ㅔ/ as it is than the young aged generations's.

The neutralization of /$s^h$/ and /$s^*$/ in Gyeongsang dialects is a culturally salient stereotype that has received relatively little attention in the phonetic literature. The current study is a more extensive acoustic comparison of the sibilant fricative productions of Seoul and Gyeongsang dialect speakers. The data presented here suggest that, at least for young Seoul and Daegu speakers, there are few inter-dialectal differences in sibilant fricative production. These conclusions are supported by the output of mixed effects logistic regression models that used aspiration duration, spectral mean of the frication noise, and H1-H2 of the following vowel to predict fricative type in each dialect. The clearest dialect difference was that Daegu speakers' /$s^h$/ and /$s^*$/ productions had overall shorter aspiration durations than those of Seoul speakers, suggesting the opposite of the traditional "/$s^*$/ produced as [$s^h$]" stereotype of Gyeongsang dialects. Further work is needed to investigate whether /$s^h/-/s^*$/ neutralization in Daegu is perceptual rather than acoustic in nature.

The aim of this paper is to show what are the sociolinguistic variables of length loss in Seoul dialect. 350 people were inquired to pronunce 40words. Among the informants, 152 were male, and198 were female. In terms of their age, 49 were twenties, 70 were thirties, 69 were forties, 71 were fifties, and 91 were above sixties. According to our statistics, 18 words show sociolinguistic variation by age, and sex was not a variable. So we can conclude that Seoul dialect is undergoing length loss by age at least. But we need to enlarge the number of words and informants and we also need to adopt other variables.

This study examines the acoustic characteristics of Korean stops of two dialects, Seoul and Kyungsang, focusing on VOT(Voice Onset Time). 8 speakers of these two dialects were asked to read 590 words which contain the stops of different places of articulation and phonation types. The results showed that overall the VOTs of Kyungsang dialect were shorter than those of Seoul dialect. This was more prominent in lenis stops than in fortis or aspirated stops. It was also shown that there were significant VOT overlapping differences between the two dialects.

American English vowels and Korean vowels were compared by the plotformant method. For American English vowels, six General American English speakers pronounced English words in the b_t environment. For Korean vowels eight Kyongsang dialect speakers and eight Seoul dialect speakers pronounced Korean words in the environments of k_t, p_t and t_t. The formant plots were obtained by plotting F1/F2 tokens of 13 American English vowels on the F1xF2 plane. In spite of personal variations the 13 vowel spaces of all six American English speakers maintained their relative positions with some overlaps. Clear distinctions were made between i-I, e-$\varepsilon$, u-$\sigma$, and o-c. The domain of c and $\alpha$ overlapped for three American English speakers, but it did not for three other speakers. The 8 Korean vowel spaces of Kyongsang dialect speakers and Seoul dialect speakers were very similar and maintained their relative positions. No distinction was made between e and $\varepsilon$. In contrast with American English e which is a neutral vowel, Korean e was a back vowel. The comparison of 13 American English vowel positions and 8 Korean Vowel positions is expected to shed some light on the errors of English vowel pronunciation of Korean learners.

This study examines the acoustic characteristics of Korean stops of two dialect, Seoul and Daegu, 20 speakers of these two dialects were asked to read 15 words containing the stops of different places of articulation and phonation types at initial. The stops in the two dialects show mainly two acoustic differences. Firstly, There was a difference in distinctive features for phonetic types in the two dialects. Secondly, lenis revel fortis`s characters in Daegu dialect.

The sentence-final rising tones of interrogatives in Seoul dialect are contrastive at lesat in two groups. One is H-type which ends in a lower pitch, the other HH-type ending in a higher one. But they are different in terms of inclinational value, also. And the latter is more adequate criterion than the former which would be available in an ideal condition.

The purpose of this experimental study is to investigate characteristics of English pitch accents uttered by Korean speakers. Six English sentences were uttered five times by fifteen male undergraduate and graduate students from three groups, Seoul, Yongnam and Honam dialect speakers. We compared the subjects' data with the data of a native speaker of English as model pronunciation of English pitch accents. Acoustic features(Fo, duration, amplitude) were measured from sound spectrograms made by the PC Works. Results showed that (1) acoustic features of English pitch accents are Fo and duration for the native speaker and Korean speakers altogether, (2) Seoul dialect speakers uttered English pitch accents more similarly to the English native speaker than the other dialect speakers and (3) Korean speakers generally have difficulties in pronouncing L* accents. It appears that Korean speakers have more problems in pronouncing L* accents than H* accents.

음성 인식 기술은 상당 기간 연구 개발이 계속적으로 되었는데 최근에 이르러 스마트 폰이 급속히 확산되면서 그 필요성, 즉, 고품질의 상용 서비스에 대한 욕구가 널리 확산되고 있다. 이런 환경에서도 사실 한국어는 상대적으로 소홀히 다뤄 질 수 있는 가능성이 매우 높다. 이러한 소외는 기술적인 문제로만 남겨지는 것이 아니라 언어라는 측면에서 문화와 직결된다. 이에 한국어 음성 인식 연구는 꼭 필요한 것이고 많은 부분 국가가 정책적으로 지원을 하는 것이 마땅하나 현 상황은 많이 미흡하나 아마도 곧 그 필요성이 대두 될 것이라 예상하며 그를 준비하는 연구로 특화된 분야, 즉, 표준어와 방언들 그리고 감정 표현 언어에 관한 연구를 한다.
