  • This paper concerns effective speaker adaptation methods to solve the over-training problem in speaker verification, which frequently occurs when modeling a speaker with sparse training data. While various speaker adaptations have already been applied to speech recognition, these methods have not yet been formally considered in speaker verification. This paper proposes speaker adaptation methods using a combination of MAP and MLLR adaptations, which are successfully used in speech recognition, and applies to speaker verification. Experimental results show that the speaker verification system using a weighted MAP and MLLR adaptation outperforms that of the conventional speaker models without adaptation by a factor of up to 5 times. From these results, we show that the speaker adaptation method achieves significantly better performance even when only small training data is available for speaker verification.

  • This paper presents a method using Maximum-Likelihood Linear Regression (MLLR) adaptation to improve recognition performance of Limabeam algorithm for speech recognition using microphone array. From our investigation on Limabeam algorithm, we can see that the performance of filtering optimization depends strongly on the supporting optimal state sequence and this sequence is created by using Viterbi algorithm trained with HMM model. So we propose an approach using MLLR adaptation for the recognition of speech uttered in a new environment to obtain better optimal state sequence that support for the filtering parameters' optimal step. Experimental results show that the system embedded with MLLR adaptation presents the word correct recognition rate 2% higher than that of original calibrate Limabeam and also present 7% higher than that of Delay and Sum algorithm. The best recognition accuracy of 89.4% is obtained when we use 4 microphones with 5 utterances for adaptation.

  • The current study examined whether multicultural students' depression level mediated between cultural adaptation stress and school life adaptation in South Korea. A total of 1,329 students in the sixth year (2016) of the National Youth Policy Institute (NYPI) 's multicultural youth panel data were analyzed using regression analysis. The main results of the study are as follows. First, cultural adaptation stress of adolescents in multicultural families had a direct influence on school life adaptation. Second, depression partly mediated between cultural adaptation stress and school life adaptation. These findings have major implications for policies and interventions in regard to cultural adaptation stress and school life adaptation of the youth in multicultrual families.

  • This study was designed to investigate the feasibility of utilizing an adaptation for selective elicitation of tactile sensations by means of transcutaneous electrical stimulation. We conducted the first experiment to investigate how the stimulation frequency affected the adaptation. Twenty healthy subjects participated in the second experiment to confirm our proposal that the perception intensity of the low-frequency vibration can be enhanced after a high-frequency adaptation, and vice versa. It was found that (1) a low-frequency stimulation did not adapt the nerve afferents responsible for the high-frequency vibration, (2) a high-frequency stimulation affected the nerve afferents responsible for the low-frequency vibration, but adapted to the pressure sensation more intensely, and (3) more than 62% of the subjects reported a more clear selective sensation after the adaptation had lessened or depressed the unwanted sensation. The observations showed that adaptation of the nerve afferent could be utilized for selective elicitation of tactile sensations.

  • Diffusion of innovation theories have been used to explain the adaptation process of Chinese college students to Korean food. This study examined and compared Korean food adaptation among Chinese college students in Gyeonggido and Daejeon. A total of 141 Chinese college students were surveyed from August 01 to November supported by the Chinese Students Association in Gyeonggido. The results show that the adaptation process of Chinese college students to Korean food was different between Gyeonggido and Daejeon. Chinese college students did not have many opportunities to learn about Korean food and search information about Korean food. The adaptation process of Chinese college students to Korean food was different by residential type and period. The adaptation process of Chinese college students in Gyeonggido to Korean food was composed of three factors: interest-reinvention-adoption, awareness, and evaluation-trial-adoption. Three factors of the adaptation process of Chinese college students in Daejeon to Korean food were awareness-evaluationtrial, adoption-reinvention-trial, and interest.

  • In this study, we looked at whether the character strength of foreign students affects the adaptation of university life and tried to figure out whether cultural adaptation stress has mediating effect. To this end, we set up a research model based on prior research, conducted a survey of 263 foreign students belonging to G City and N City, and analyzed the data using the spss statistics program. As a result of the study, the character strength of foreign students was affecting the adaptation of university life, and the cultural adaptation stress of international students partially mediated the relationship between character strength and university life adaptation. Therefore, it is suggested that it is necessary to develop a program that reduces cultural stress and to have a professional counselor in the university who can continuously consult international students.

  • This study is aimed at analyzing the characteristics of adaptation to college life among freshmen of D University by utilizing the DEU-GRIT test. To achieve this, we examined differences in level of college life adaptation according to gender and major, and explored the characteristics of college life adaptation among college freshmen who were clustered based on their level of academic, social, emotional, and career adaptation, which is an important factor in adaptation to college life. Moreover, based on the DEU-GRIT test standards, we also explored the characteristics of their college life adaptation by sorting out low level groups of freshmen with difficulties adapting. The results demonstrated that male students had a higher level of emotional adaptation than female students, and that science and technology majors had higher levels of academic and emotional adaptation than students in the humanities and society majors. Furthermore, a cluster analysis based on 4 factor levels of college life adaptation showed that cluster 1 had a high level of adaptability to all factors, but cluster 3 had a low level of adaptability to all factors. Moreover, while cluster 2 showed a high level of emotional adaptation, cluster 4 showed a low level of emotional adaptation. On the other hand, a lower-standard group of DEU-GRIT tests showed that the level of academic adaptation and social adaptation was higher among female students than among male students. However, the overall level of college life, academic, and emotional adaptation were higher among science and technology students than among those majoring in humanities and social studies. In addition, a cluster analysis based on the level of 4 factors of college life adaptation of lower-standard groups showed that cluster 1 of the lower-standard groups had a high level of emotional adaptation, while cluster 2 of the lower-standard groups had a low level of emotional and career adaptation and a high level of academic and social adaptation. Also, cluster 3 of the lower-standard groups was found to have low levels of all factors, and cluster 4 of the lower-standard groups showed low levels of social and emotional adaptation and high levels of academic and career adaptation. This indicates that, in terms of social and emotional adaptation among freshmen, participation in psychological counseling programs tailored according to gender is necessary and, regarding the major, relative emotional intervention is required due to the high and low expectations of job prospects. In conclusion, the emotional and social adaptation to college life among the lower-level groups is likely to serve as a protective factor for college life adaptation, suggesting that specific intervention should be contemplated.
