The paper discusses the way in which speech sounds are being evaluated and transcribed in various fields of speech sciences, and suggests ways for a more accurate transcription. The academic fields explored are of phonetics, speech processing, speech pathology, and foreign language education. The discussion centers on the International Phonetic Alphabet (IPA), most commonly used in these fields, and other less widely-accepted transcription conventions such as the TOnes and Break Indices (ToBI), the Speech Assessment Methods Phonetic Alphabet (SAMPA), an extension of the official Korean Romanization (KORBET), and the American-English transcription system in the TIMIT database (TIMITBET). These transcription conventions are dealt with Korean, English, and Korean-accented English. The paper demonstrates that each transcription can exclusively be recommended for a specific need from different academic fields. Due to its publicity, the IPA is best suited for phonetic evaluation in the fields of phonetics, speech pathology, and foreign language education. The rest of the transcriptions are useful for keyboard-inputting the phonetically evaluated data from all these fields as well as for sound transcription in speech engineering, because they use convenient letter symbols for typing, searching, and programming. Several practical suggestions are made to maintain the transcriptional efficiency and consistency to accommodate the intra-and inter-transcriber variability.

In Korean, as with Kana and Kanji in Japanese, two kinds of word-writing systems--Hangul (the Korean alphabet) and Hanja (the Chinese character; Kanji in Japanese)--have been and still are being used. Hangul is phonetic while Hanja is ideographic. A phonetic alphabet represents the pronunciation of words, wheras ideographs are where a character of a writing system represents a concept. Aphasics suffer from language disorders following brain damage. The reading and writing of Hangul and Hanja by two Korean Broca's aphasics were analyzed with two goals. The first goal was to confirm the functional autonomy of reading and writing systems in the brain that has been argued by other researchers. The second goal was to reveal what difference the subjects show in reading and writing Hangul and Hanja. As experimental materials, 50 monosyllabic words were chosen in Hangul and Hanja respectively. The 50 word pairs of Hangul and Hanja have the same meaning and are also the most familiar monosyllabic words for a group of normal adults in their fifties and sixties. The errors that the aphasic subjects made in performing the experimental materials are analyzed and discussed here. This analysis has confirmed that reading and writing systems are located in different parts in the brain. Furthemore, it seems clear that the two writing systems of Hangul and Hanja have their own respective processes.

한국어 문서에서 외래어 표기는 한 단어에 대해 한 개만 존재하는 것이 아니라 여러 개의 다른 표기로 사용되고 있다. 이러한 표기상 불일치는 하나의 단어가 다른 개념으로 인식되어 정보 검색 시스템의 성능 저하의 원인이 된다. 따라서 정보 검색 시스템에서는 다양한 외래어 표기에 대해 같은 개념으로 인식하여 검색할 수 있도록 외래어 표기법에 맞는 외래어 표기로 교정하는 전처리가 필요하다. 본 논문에서는 질의어로 외래어가 입력되면, 이를 근거로 외래어 표기법에 맞는 외래어 표기로 교정해주는 방법을 제안한다. 제안하는 기법은 한국어 자모의 viable prefix를 이용하여 후보 외래어 표기를 생성하는 가상 트리를 작성하고 불필요한 외래어를 가지치기함으로써 검색 정확도를 높이고 속도를 개선한다.

A few people are frequently using Korean text entry function in the mobile phone. To make matters worse, too many kinds of Korean text entry methods exist in the market, compelling mobile phone users to learn how to input texts all over again, whenever they purchase a new mobile phone. The purpose of this study is to propose a universal design of Korean text entry method for mobile phones. Several experiments and several questionnaire surveys were conducted in order to induce design factors for the universal design. Participants were mobile phone users with the diverse levels of text entry expertise and with the diverse ages. The results of this investigation were identical, irrespective of participants' age and expertise. The efficiency of the text entry method was not more important factor than memorability. The layout of vowels to keypad was preferred to map just 3 strokes to the 3 buttons so that users can make for themselves vowels that they want to input. The preference on the consonants layout was different according to investigation methods. According to the survey, it was preferred that consonants were arranged by alphabet order. However, the result of text entry speed measurement was that the arrangement by alphabet order was not superior to the typical arrangement. Such results may be used to design mobile phones for diverse users.

HunMinJeongEum, meaning "the right sound to teach the people," was created in 1443 CE by King Sejong the Great, the fourth king of the Joseon Dynasty. In today's modern language, this letter, called Hangeul, is internationally recognized for its linguistic science. However, it is hard to find a comprehensive study on the fact that King Sejong himself created Hangeul, the Confucian perspective on natural disasters and democracy revealed in the process of writing, the independent efforts emphasized from a certain period, and the achievements of King Sejong, who shared the sorrow of the people and carried out national policies despite the extreme opposition of the nobility. Accordingly, I analyzed the consonants of HunMinJeongEum and looked at the essence of humanity and oriental philosophy (Yin-Yang Five Elements, Sangsu Philosophy, Hado). Surprisingly, different meanings from previous studies and interpretations were found, and King Sejong's "Da Vinci Code," which was left behind in the process of making the consonant, is reinterpreted and revealed. King Sejong's achievements were all connected as one. This is the root of democracy in the Republic of Korea today, and this is why King Sejong was selected as the most beloved and respected historical figure by the Korean people. This study will start with more people's understanding of the fundamental perception and philosophy of the world in Asia, including Korea, to reinterpret and reveal the hardships and great achievements experienced by a leader of a country in the process of creating korean alphabet, and to emphasize democracy, which is an important value for Asians and Westerners' mutual respect and co-prosperity.

본 논문에서는 흑백 CCD 카메라로부터 입력되는 2가지 인쇄체(바탕, 돋움) 영문자를 인식하여 편집 가능한 텍스트 형식으로 변환하는 시스템을 구현하였다. 입력된 인쇄체 영어 문장 영상을 이진화 처리 후. 히스토그램 기법을 적용하여 수평 투영으로 각 문장의 행을 분리하고 수직 투영으로 개별 문자를 분리하였으며, 문자의 높이를 48픽셀로 변환하여 정규화 하였다. 정규화 된 개별 문자에 노노그램 퍼즐 원리를 역으로 이용하여, 픽셀을 단위로 하는 작은 사각형들로 구성된 사각형으로 문자를 덮은 후 문자의 특성을 노노그램 퍼즐의 수치 정보로 나타내어 표준 패턴 정보와 비교하여 인식하게 하였다. 바탕체 2609개, 돋움체 1475개의 문자를 대상으로 실험하여 100% 인식률을 얻었다.

The purpose of this study was to investigate predictors concerning preschoolers' ability to read words, in terms of their sub-skills of alphabet knowledge, phonological awareness, and phonological processing. Fourteen literacy sub-tests and three types of reading tasks were administered to 289 kindergartners aged 4 to 6 in Busan. The main results are as follows. Sub-skills that predicted reading ability varied with children's age. Irrespective of children's age groups, knowledge of consonant names and digit naming speed commonly explained the reading of real words. In contrast, skills of syllable deletion and phoneme substitution and knowledge of alphabet composition principles were related to only 4-year-olds' reading skills. Exclusively included was digit memory in predicting 5-year-olds' reading abilities, and knowledge of vowel sounds in 6-year-olds' reading skills. The type of reading task also influenced reading ability. A few common variables such as knowledge of consonant names and vowel sounds, digit naming speed, and phoneme substitution skill explained all types of word reading. Syllable counting skills, however, had predictive value only for the reading of real words. Phoneme insertion skills and digit memory had predictive value for the reading of pseudo words and low frequency letters. Likewise, knowledge of consonant sounds and vowel stroke-adding principles were significant only for the reading of low frequency letters.

For the efficient recognition of Korean Alphabets, a tree structure discrimination algorithm employing NRF-SDF concept is proposed. This algorithm consists of several main-steps, which contain several sub-steps. Each step contains vowels or consonants for training image. This algorithm reduces processing and recognition time than any other conventional algorithms for recognition of Korean Alphabets. A simulation results indicated that this algorithm has a satisfactory performance.
