The purpose of this study is to identify potential semantic landscape makeup of "the Forty Eight Poems of Soswaewon" according to Yin-Yang and Five Elements Principle(陰陽五行論). that speculation system between human's nature and cosmical universal order. Existing academic discussions made so far concerning this topic can be summed up as follows: 1. Among Yin-Yang-based landscape makeups of the Forty Eight Poems of Soswaewon, poetic writings for embodiment of interactions between nature and human behaviors focused on depicting dynamic aspects of a poetic narrator when he appreciates or explores hills and streams as of to live free from worldly cares. Primarily, many of those writings were created on the east and south primarily through assignment of yang. On the other hand, poetic writings for embodiment of nature and seasonal scenery - as static landscape makeup of yin - were often created on or near the north and west for many times. Those writings focusing on embodiment of nature and artificial scenery as a work are divided into two categories: One category refers to author Kim In-hu's expression of semantic landscape from seasonal scenery in nature. The other refers to his depiction of realistic garden images as they are. In the Forty Eight Poems of Soswaewon, the poetic writings show that author Kim focused on embodying seasonal scenery rather than expressing human behaviors. In addition, both Poem No. 1 and Poem No. 48(last poem; titled 'Jangwon Jeyeong') were created in a same place, which author Kim sought to understand the place as a space of beginning and end where yin and yang - i.e. the principle of natural cycle - are inherent. 2. According to construction about landscape in the Forty Eight Poems of Soswaewon on the basis of Ohaeng-ron (five natural element principle), it was found that tree(木) and fire(火) are typical examples of a world combined by emanation. First, many of poetic writings depicting the sentiments of tree focused on embodying seasonal scenery and were located in the place of Ogogmun(五曲門) area in the east, from overall perspective of Soswaewon. The content of these poems shows generation and curve / straightness in flexibility and simplicity. Many of poems depicting the sentiments of fire(火) focused on embodying human behaviors, and they were created in Aeyangdan area on the south of Soswaewon over which sun rises at noon. These poems are all on a status of side movement that is characterized by emanation and ascension which belong to attributes of yang. 3. With regard to Ohaeng-ron's interpretation about landscape in the Forty Eight Poems of Soswaewon, it was found that metal(金) and water(水) are typical examples of world combined by convergence. First, it was found that all of poems depicting sentiments of metal focused on embodying seasonal scenery, and were created in a bamboo grove area on the west from overall perspective of Soswaewon. They represent scenery of autumn among 4 seasons to symbolize faithfulness vested in a man of virtue(seonbi) with integrity and righteousness. Poems depicting sentiments of water were created in vicinity of Jewoldang on the north, possibly topmost of Soswaewon. They were divided into two categories: One category refers to poems embodying actions of welcoming the first full moon deep in the night after sunset, and the other refers to poems embodying natural scenery of snowscape. All of those poems focused on expressing any atmosphere of turning into yin via convergence. 4. With regard to Ohaeng-ron's interpretation of landscape in the Forty Eight Poems of Soswaewon, it was found that poems depicting sentiments of earth(土), a complex body of convergence and emanation, were created in vicinity of mountain stream around Gwangpunggak which is located in the center of Soswaewon. These poems focused on carrying actions of author Kim by way of natural phenomena and artificial scenery.

Because of their human-like synthesized speech quality, recently Corpus-Based Text-To-Speech(CB-TTS) have been actively studied worldwide. However, due to their large size speech database (DB), their application is very restricted. In this paper we propose and evaluate three DB reduction algorithms to which are designed to solve the above drawback. The first method is based on a K-means clustering approach, which selects k-representatives among multiple instances. The second method is keeping only those unit instances that are selected during synthesis, using a domain-restricted text as input to the synthesizer. The third method is a kind of hybrid approach of the above two methods and is using a large text as input in the system. After synthesizing the given sentences, the used unit instances and their occurrence information is extracted. As next step a modified K-means clustering is applied, which takes into account also the occurrence information of the selected unit instances, Finally we compare three pruning methods by evaluating the synthesized speech quality for the similar DB reduction rate, Based on perceptual listening tests, we concluded that the last method shows the best performance among three algorithms. More than this, the results show that the last method is able to reduce DB size without speech quality looses.

Though Android-based smart phones are being released in Korea, Korean TTS engine is not built on them and Google has not announced service or software developer's kit related to Korean TTS officially. Thus, application developers who want to include Korean TTS capability in their application have difficulties. In this paper, we design and implement Android OS-based Korean TTS system and service. For speed, text preprocessing and synthesis libraries are implemented using Android NDK. By using Java's thread mechanism and the AudioTrack class, the response time of TTS is minimized. For the test of implemented service, an application that reads incoming SMS is developed. The test shows that synthesized speech are generated in real-time for random sentences. By using the implemented Korean TTS service, Android application developers can transmit information easily through voice. Korean TTS service proposed and implemented in this paper overcomes shortcomings of the existing restrictive synthesis methods and provides the benefit for application developers and users.

This paper aimed to find out the differences of DDK performances of 37 normally developing children in the range of 4-6 years. DDK tasks included with the Consonant-Vowel(CV) syllables and with the Vowel-Vowel(VV) syllables. For DDK rate, all spoken AMR and SMR in one second were measured by Multi-Speech, and analyzed with Motor Speech Profile for DDK regularity. Error frequency and type in DDK performance were transcribed and auditorily judged by two professional speech pathologists. The findings in this study were follow as: First, DDK rate became faster as the age of children were increased. But there were no statistical differences between the groups for age. Second, there was no significant differences the CV and VV syllables of DDK tasks. Third, the frequency of articulatory error in DDK performance was significantly higher in the age of 4 than other two groups.

하천의 수심, 유속, 하상경사, 하상재료, 만곡도 등과 같은 물리적 특성에 따라 생물서식처로서 다양한 특성을 나타내고 그 특성들에 의해 서식처의 유형을 구분할 수 있다. 이러한 서식처 유형에 따라 수중음향의 특성이 달라지며, 수중음향의 서식지의 양적 표시자로서 잠재력으로 인해 최근 많은 연구들이 시도되고 있다. 본 연구에서는 인공적인 영향을 적게 받은 자연하천으로 양양 남대천 12개 지점을 대상으로 하여 서식지의 형태에 따른 수중음향과 하천의 수리적 인자에 따른 관계를 파악하고자 하였다. 서식처 유형으로는 빠른 유속에 얕은 수심을 가지고 있는 여울(riffle), 수심이 깊고 유속이 느린 소(pool), 낙차가 있는 계단형 여울(step riffle)에 대해 조사하였다. 수중배경음은 여울과 계단형 여울이 유사하게 나타났으며 소는 상대적으로 낮은 배경음을 나타내었다. H2, H4, H5, H9, H10 지점은 여울 형태로 유속에 따라 H2, H5, H4, H9 지점 순으로 음압레벨이 낮아지는 경향을 보였으며, H10지점은 H9, H4 지점에 비해 낮은 유속임에도 높은 음압레벨을 보였다. 이는 H10 지점의 하상이 조도가 매우 큰 전석으로 이루어져 나타나는 현상으로 판단된다. H3, H6, H7, H8, H12 지점은 소 형태로 H12 지점을 제외하고 대체로 낮은 음압레벨을 보였으며, H3과 H6지점에서는 저주파수에서 높은 음압레벨을 보였다. 이는 수심이 깊은 경우 상류의 저주파수의 음파가 잘 전달되기 때문으로 판단된다. H1과 H11지점은 계단형 여울로 낮은 수심에서 빠른 유속을 가진 H11지점과 느린 유속을 가진 H1 지점에서 대체로 높은 음압레벨을 나타내었다. 이는 낙차에 의한 수중음향 발생에 의한 것으로 판단된다. 세 가지 유형에 따른 수중 음향을 비교하였을 때 음압레벨은 계단형 여울, 여울, 소 순서로 높게 나타났다. 결과적으로 수중음향이 서식처의 수리적 특성에 따라 다양한 특성을 나타내고 있으며, 이를 통해 생물서식처를 평가하기 위한 새로운 방법으로 수중음향의 활용 가능성을 제시하였다.

Recent advances in text-to-speech (TTS) technology have significantly improved the quality of synthesized speech, reaching a level where it can closely imitate natural human speech. Especially, TTS models offering various voice characteristics and personalized speech, are widely utilized in fields such as artificial intelligence (AI) tutors, advertising, and video dubbing. Accordingly, in this paper, we propose a one-shot multi-speaker TTS system that can ensure acoustic diversity and synthesize personalized voice by generating speech using unseen target speakers' utterances. The proposed model integrates a speaker encoder into a TTS model consisting of the FastSpeech2 acoustic model and the HiFi-GAN vocoder. The speaker encoder, based on the pre-trained RawNet3, extracts speaker-specific voice features. Furthermore, the proposed approach not only includes an English one-shot multi-speaker TTS but also introduces a Korean one-shot multi-speaker TTS. We evaluate naturalness and speaker similarity of the generated speech using objective and subjective metrics. In the subjective evaluation, the proposed Korean one-shot multi-speaker TTS obtained naturalness mean opinion score (NMOS) of 3.36 and similarity MOS (SMOS) of 3.16. The objective evaluation of the proposed English and Korean one-shot multi-speaker TTS showed a prediction MOS (P-MOS) of 2.54 and 3.74, respectively. These results indicate that the performance of our proposed model is improved over the baseline models in terms of both naturalness and speaker similarity.
