The purpose of this paper is to extract the vowel formants of the ten young male speakers from the Buckeye Corpus of Conversational Speech [1] and to analyze them in comparison to earlier works in terms of various phonetic factors that are expected to affect the realization of the formant distribution. The first two formant frequency values were automatically extracted with a Praat script along with such factors as the place of articulation, the content versus function word information, syllabic stress information, the location in a word, location in utterance, speech rate of three consecutive words, and the word frequency in the corpus. The results indicated that the formant patterns from the corpus were very different from those of earlier works although the overall pattern was similar and that the factors were strongly responsible for the realization of the two formants.

The purpose of this study is to reveal the Korean learners' usage pattern of '의', the genitive particle, according to semantic classification, so that it can be referred to in determining the contents and methods of related education. The method of this study adopts a quantitative analysis using learners corpus established by National Institute of Korean Language. As a result of the analysis, as proficiency increases, the overall frequency of '의' increases and the number of meaning senses used increases. However, the frequency of errors also increases with it. As for the usage pattern of each sense, the meaning of 'ownership, belonging' is the most frequent, and followed by 'acting entity', 'kinship, social relations', and 'relationship(area)'. In conclusion, the meanings of 'acting subjects' and 'relationships(area) need to be supplemented with explicit education. Other meanings need to be discussed, and decisions should be made in consideration of learning purpose and proficiency.

This paper presents an acoustic and phonological study of the alveolar flaps in American English. Based on the Buckeye Corpus, the flapping tokens produced by twenty men are analyzed at both lexical and post-lexical levels. The data, analyzed with Pratt speech analysis, include duration, F2 and F3 in voicing during the flap, as well as duration, F1, F2, F3, and f0 in the adjacent vowels. The results provide evidence on two issues: (1) The different ways in which voiced and voiceless alveolar stops give rise to neutralized flapping stops by following lexical and post-lexical levels, (2) The extent to which the vowel features (height, frontness, and tenseness) affect flapping sounds. The results show that flaps are affected by pre-consonantal vowel features at the lexical as well as post-lexical levels. Unlike previous studies, this study uses the Praat method to distinguish flapped from unflapped tokens in the Buckeye Corpus and examines connections between the lexical and post-lexical levels.

The purpose of this work is to examine the English and Korean voiceless plosives from the Buckeye[15] and Seoul[16] corpus in terms of their static spectral characteristics. The plosives were automatically extracted by a Praat script. In order to estimate the percent correctness in the classification of the plosives, discriminant analyses were performed whose trainings were based on four spectral moments, i.e. the center of gravity, variance, skewness and kurtosis as suggested in [6]. Another set of discriminant analyses were performed based on the spectral tilts. In the last set of analyeses, the spectral moments and tilts were both used in the training. Results showed that the correct classification rate did not exceed around 65% in the best case, which suggested that phonetic cues other than the release burst would be necessary including the dynamic spectral aspects and vowel-onset cues.

The purpose of this paper is to measure the first two vowel formants of the ten young female speakers from the Buckeye Corpus of Conversational Speech [1] automatically and then to analyze various potential factors that may affect the formant distribution of the eight peripheral vowels of English. The factors that were analyzed included the place of articulation, the content versus function word information, the syllabic stress information, the location in a word, the location in an utterance, the speech rate of the three consecutive words, and the word frequency in the corpus. The results indicate that the overall formant patterns of the female speakers were similar to those of earlier works. The effects of the factors on the realization of the two formants were also similar to those from the male speakers with minor differences.

The paper investigates the acoustic characteristics of English fricatives in the TIMIT corpus, with a special focus on the role of voicing in rendering fricatives in American English. The TIMIT database includes 630 talkers and 2,342 different sentences, and comprises more than five hours of speech. Acoustic analyses are conducted in the domain of spectral and temporal properties by treating gender, voicing, and place of articulation as independent factors. The results of the acoustic analyses revealed that acoustic signals interact in a complex way to signal the gender, place, and voicing of fricatives. Classification experiments using a multiclass support vector machine (SVM) revealed that 78.7% of fricatives are correctly classified. The majority of errors stem from the misclassification of /θ/ as [f] and /ʒ/ as [z]. The average accuracy of gender classification is 78.7%. Most errors result from the classification of female speakers as male speakers. The paper contributes to the understanding of the effects of voicing and gender on fricatives in a large-scale speech corpus.

This study focused on the meaning of 'educational philosophy' by the method of corpus analysis. There is the difference of meaning on educational philosophy between professional researchers and publics. This semantic phenomenon implies that the image acoustics of 'educational philosophy' are not matched between two groups. This study, which originated from Saussure's linguistics theory, examined the semantics of educational philosophy in the . Unlike philosophical inquiry on education, the definition of educational philosophy, the general public use 'educational philosophy' like the connotation of secret of successful learning and child nurturing. Given the power of the media and the mass, these tendency could affect the meaning and definition of educational philosophy. Professional researchers should investigate these acoustic image from the sense of linguistic and educational approaches. These researches could contribute to clarify descriptive and normative meaning of the educational philosophy.

이 연구는 담화 표지 '아, 어, 음'의 출현 빈도와 발화 시간, 발화 위치 등을 계량적으로 관찰하여 성별과 연령별 차이를 보이고자 하였다. 이를 위해 대용량 음성 코퍼스인 서울코퍼스를 이용하였고, Praat(ver.6.1.31)으로 음길이와 실제 발화를 확인하고, Emeditor(ver.17.6.1)로 코퍼스를 분석하고, R(ver.3.4.4)로 통계 분석하여 결과를 제시하였다. 성별에 따라 보면 여성의 경우 남성보다 단독 발화에서 '음'이 고빈도로 사용되었고, 발화 종결 위치에서의 평균 음길이 또한 길었다. 연령에 따라 보면 발화 시작 위치에서 10대에서는 '아'가, 40대는 '어'가 고빈도로 출현하는 것이 특징적이었다.

본 코퍼스 기반 연구는 통사론 영역에서 자주 등장하는 학술어휘들을 목록화하고 추출된 단어 목록을 Coxhead(2000)의 학술어휘 목록(AWL) 및 West(1953)의 기본어휘 목록(GSL)과 비교하여 통사론 코퍼스 내의 어휘 분포와 범위를 조사하였다. 이를 위해 영어교육 전공자들이 주로 사용하는 필수 통사론 전공 서적을 546,074 단어 수준의 전문 코퍼스로 구축한 다음 AntWordProfiler 1.4.1로 분석하였다. 빈도를 기준으로 분석한 결과 16회 이상 등장한 학술어휘는 288개(50.5%), 15회 이하 등장한 학술어휘는 218개(38.2%)로 나타났다. AWL과 GSL의 출현 범위는 각각 9.19%와 78.92%로 나타났으며 GSL과 AWL을 포함한 비중은 전체 토큰의 88.11%에 달하였다. AWL이 광범위한 학술 요구를 충족시키는데 중추적인 역할을 할 수 있다는 점을 감안할 때, 본 연구는 학문 문식성과 학업 능력을 향상시키기 위한 방안으로 학문 분야별 학술 어휘목록을 편성할 필요가 있음을 강조하였다.

Text data plays a significant role in understanding and analyzing trends in consumer, business, and social sectors. For text analysis, there must be a corpus that reflects specific domain knowledge. However, in the field of fashion, the professional corpus is insufficient. This study aims to develop a taxonomy and thesaurus that considers the specialty of fashion products. To this end, about 100,000 fashion vocabulary terms were collected by crawling text data from WSGN, Pantone, and online platforms; text subsequently was extracted through preprocessing with Python. The taxonomy was composed of items, silhouettes, details, styles, colors, textiles, and patterns/prints, which are seven attributes of clothes. The corpus was completed through processing synonyms of terms from fashion books such as dictionaries. Finally, 10,294 vocabulary words, including 1,956 standard Korean words, were classified in the taxonomy. All data was then developed into a web dictionary system. Quantitative and qualitative performance tests of the results were conducted through expert reviews. The performance of the thesaurus also was verified by comparing the results of text mining analysis through the previously developed corpus. This study contributes to achieving a text data standard and enables meaningful results of text mining analysis in the fashion field.
