The speech of Sino-Korean has been evolved from geopolitical cause since 1945. The aim of this study is to collect Yanji dialectal speech and to compare with South Korean dialectal speech. Twenty Yanbian university students participated as informants. Acoustic speech informations are analyzed using the Multi-Speech Windows Vista version. Dialectal speech characteristics of Yanji sino-Korean showed posterior vowel /${\alpha}$/, neutralization of mid-vowel /o/ between /o/ and /Ɔ/. Lenis stop sound showed the tendency of glottalization based on VOT value. Sibilant sound contains aspiration following constriction and lateral /l/ realized the approximant /r/.

《官話類編》是一部美國傳教士Calvin Wilson Mateer1892編寫的漢語教科書. 他1864年來華之後為了有效的传道编写語言學, 数学, 科学等方面的教科书并设立了山东养学堂和登州学会馆, 中国教育史上出了不少贡献. 《官話類編》是花25年的时间, 进行对北京, 南京, 九江, 潍县方言的方言调查后编写的, 内容簡單而且日常会话为主, 收到当时来华传教士的欢迎. 当时北京官话被认为是最时髦, 最流行的方言, 成为官方的公式语言. 虽然南方官话不是主流, 但还是在中国的更大地区里接受的官话方言. 《官話類編》里的北京官话有疑母消失, 见, 精组合流, 保存iai韵母, 梗曾摄, 宕江摄, 通摄存在文白异读等特征, 他记录的南京官话有见精组对立, 疑母消失, 保存入声和iai韵母, n, l和n, ŋ想混的特征, 为了解当时语言使用的情况以及音韵特征提供很有价值的信息.

Acoustically a naturally-spoken vowel is composed of five formants. However, the acoustic quality of a vowel is known to be mostly determined by $F_1\;and\;F_2$. The main purpose of this study was to examine how synthesized vowels with $F_1\;and\;F_2$ are perceived by Korean native speakers. In addion, we are interested in finding whether the synthesized vowels are perceived differently by standard Korean speakers and Kyungnam regional dialect speakers. In the experiment 9 Seoul standard Korean speakers and 9 Kyungnam dialect speakers heard 536 vowels synthesized in vowel space with $F_1\;by\;F_2$ and categorized them into one of 10 Korean vowels. The resultant vowel map showed that each Korean vowel occupies an unique area in the two-dimensional vowel space of $F_1\;by\;F_2$, and confirmed that $F_1\;and\;F_2$ play important roles in the perception of vowels. The results also showed that the Seoul speakers and the Kyungnam speakers perceive the synthesized vowels differently. For example, /e/ versus /$\varepsilon$/ contrast, /y/, and /$\phi$/ are perceived differently by the Seoul speakers, whereas they were perceptually confused by the Kyungnam speakers. These results might be due to the different vowel systems of the standard Korean and the Kyungnam regional dialect. While the latter uses a six-vowel system which has no /e/ vs /$/ contrast, /v/ vs /i/ contrast, /y/, and /$\phi$/, the former recognizes these as different vowels. This result suggests that the vowel system of differing dialect restricts the perception of the Korean vowels. Unexpectedly /i/ does not occupy any area in the vowel apace. This result suggests that /i/ cannot be synthesized without $F_3$.

This study attempted to acoustically analyze the diphthongs of native Jeju speakers in their 70s, 50s, and 20s to observe their diphthong inventories 96 subjects participated in the recording using a set of picture cards. Results show that Jeju dialect speakers in their 70s distinguish /we/ and $/w{\varepsilon}/$, /yo/ and /yc/, but have difficulty pronouncing /ye/, $/y{\varepsilon}/$, and /iy/ correctly. It is interesting to find that the diphthong inventory of Jeju dialect speakers in their 50s are in transitional stage. They share the diphthong inventories of those people in their 70's containing /we/ and $/w{\varepsilon}/$, and /yo/ and /yc/, but they do not produce them as clearly as the latter age group. The former age group also share the common feature with those people in their 20's because both age groups show the same pronunciation of /iy/. The youngest group seldom pronounce /we/ and $/w{\varepsilon}/$, /yo/ and /yc/ correctly unlike native Jeju speakers in their 70s, but they can easily pronounce the diphthong /iy/ like standard Korean speakers.

The purpose of this experimental study is to investigate and compare the. vowel lengths of English diphthongs and low vowels among native-English-speaking Americans with Korean college students from the Chungnam and Gyungnam provinces. Eight words and sixteen sentences were uttered five times by twenty five subjects from three groups; 1) Chungnam dialect speakers, 2) Gyungnam dialect speakers and 3) five native-English-speaking Americans. Acoustic features (duration) were measured from sound spectrograms made by the PC Quire. Results showed that the vowel lengths of English diphthongs and low vowels between native English speakers and Korean collegians of Chungnam and Gyungnam provinces were different. Comparing the average length of English diphthongs of Korean collegians with those of American natives, we can see that native English speakers tend to pronounce the English diphthongs shorter than Korean collegians do. However, native English speakers tend to pronounce the English low vowels longer than Korean collegians do. In this study we also tried to find out the differences of English diphthongs and low vowel lengths in relation to their utterance positions among American natives and Chungnam and Gyungnam dialect speakers. By the results of this experiment, we observed a lengthening effect in the three groups. However, in the pronunciation of American natives, a lengthening effect of English vowels was more clearly observed, especially in the pronunciation of English diphthongs.

The purpose of this study was to explore how married female immigrants adjust to their lives in Korea. A total of 15 women from three different countries participated in the study. The major issues that these women faced included communication breakdowns with their husband and other family members, financial problems as well as problems with raising children in a different culture. The findings showed that such problems were usually rooted in a lack of Korean cultural knowledge and skills. Additionally, the inaccurate use of the language by married female immigrants who have lived in Korea for longer than six months was often fossilized. For instance, because they usually learned the language in a local dialect, it took them longer to distinguish the dialect from standard Korean. The results found that married female immigrants who received both Korean lessons and family life education instructions overcame their culture shock and adapted to Korean culture more easily than those who did not receive such instructions.

Speech can actively elicit feelings and attitudes by using words. It is important for researchers to identify the emotional content contained in speech signals as well as the sort of emotion that resulted from the speech that was made. In this study, we studied the emotion recognition system using a database in Arabic, especially in the Saudi dialect, the database is from a YouTube channel called Telfaz11, The four emotions that were examined were anger, happiness, sadness, and neutral. In our experiments, we extracted features from audio signals, such as Mel Frequency Cepstral Coefficient (MFCC) and Zero-Crossing Rate (ZCR), then we classified emotions using many classification algorithms such as machine learning algorithms (Support Vector Machine (SVM) and K-Nearest Neighbor (KNN)) and deep learning algorithms such as (Convolution Neural Network (CNN) and Long Short-Term Memory (LSTM)). Our Experiments showed that the MFCC feature extraction method and CNN model obtained the best accuracy result with 95%, proving the effectiveness of this classification system in recognizing Arabic spoken emotions.
