There are various application areas of Language information processing such as information retrieval, morphological analysis, spell checker, voice recognition, character recognition, etc. In these language information processing areas, an electronic dictionary is essential. This thesis made researches on basic statistical information on the Korean dictionary and on the construction of electronic dictionary. The targets of analysis were the number of registered word in Korea dictionary, the entry number of registered word in electronic dictionary, the number of used syllables, the number of different syllables, the average length of entry, the distribution of part of speech and the number of used nodes to construct electronic dictionary using Trie, except for words including a archaic word or incomplete syllables. Total entry number of electronic dictionary is 361,980, the number of used syllables is 1,289,659, the average length of entries is 3.56 and the number of different syllables is 2,463. Theses informations would play a beneficial role in constructing an electronic dictionary and in processing Korean information.

In this paper we present a Hangul Encryption Algorithm (HEA) which encrypts composition Hangul syllables into composition Hangul syllables using the non-linear structure of Hangul. Since ciphertexts generated by HEA are displayable characters HEA can be used in applications such as Privacy Enhanced mail (PEM) where ciphertexts should be displayable characters. HEA is based on DES and it can be shown that HEA is as safe as DES against the exhaustive key search differential cryptanalysis and linear cryptanalysis. HEA also has randomness of phonemes of ciphertexts and satisfies plaintext-ciphetext avalanche effect and key-ciphertext avalanche effect.

This thesis compares the duration aspect of Daegu tongue with that of standard Korean. In the former study on the rhythm of standard Korean, one of the purposes of the study was to compare it with dialects. This thesis is the first attempt In do that. For this purpose, this thesis proceeds as follows. After Introduction, Chapter 2 surveys the former study, Chapter 3 deals with the materials, method and results of the experiment. Chapter 4 analyzes and interprets the results of the experiment. In Conclusion, the most prominent fact is that the results of the experiment fall short of Daegu tongue speakers' expectations. Daegu tongue is generally considered as ' tone language. ' And as Daegu tongue speakers sensitively recognize pitch, they think that they quitckly say the syllables between the pitch stressed syllables, whereas standard Korean speakers say those syllables relatively slowly. But in this experiment, which deals with only duration ignoring pitch, their assumption is proved to be false.

This paper investigated the effects of frequency band limitation on perceptual characteristics of Korean vowels. Monosyllabic speech (144 syllables of CV type, 56 syllables of VC type, 8 syllables of V type) produced by two announcers were low- and high-pass filtered with cutoff frequencies ranging from 300 to 5000 Hz. Six listeners with normal hearing performed perception tests by types of filter and cutoff frequencies. We reported phoneme recognition rates and types of perception error of band-limited Korean vowels to examine how frequency distortion in the process of speech transmission affect listener's perception.

The purpose of this paper IS to investigate the aspects of errors of English stress by Korean students. In this experimental study, 17 students participated and read 120 words which are divided into three types-the beginning, the middle, and the advanced-according to the level of words. As a result of acoustical judgement, there were a greater number of errors In the advanced level of words, and the more syllables the words have, the more errors occurred, tins means Korean students who learn English as a second language have trouble realizing the right stress in words with larger numbers of syllables and the more advanced level. Furthermore it is interesting that Korean students imposed the primary stress on the second syllable when producing words with stress in the first, third and forth syllables.

Not all linguistic units are of equal importance in the functioning of language. The present study aims to examine He functional load of phonemes in standard Korean, To achieve this goal, B analysed continuous texts selected from the textbooks of elementary school on a personal computer. The total number of syllables studied in this thesis is 101,637. The characteristics of the Korean syllable structures are as follows. 1) In a syllable head, /n/ occurs most frequently. 2) The frequencies of syllables with an onset are much higher than those with no onset ( 85% : 15% ), 3) In a syllable head, obstruents are preferred because their consonantal strength are great, (57%) 4) In a syllable nucleus, /a/ occurs most frequently. 5) The rate of occurrence of the monophthongs is 90.2%, and that of the diphthongs is 9.8%. Especially the three basic vowels(/i,a,u/) occur at the rate of 46.6%. 6) In a syllable coda, /n/ occurs most frequently. 7) The open syllables are favored (open syllable 68.7%, closed syllable 31.3%).

From a population in Kang-Nae, Cheong-won, Chung-Buk, acoustic behaviours of Gray-headed Bunting (Emberizo fucata) were obsenred. The singing of males was classified into two major types, stereotyped song and squeaky song. The stereotyped songs of eight territorial males were recorded Intraindividual and individually distinctive features were studied. Individuals produced their song in distinctive ways in terms of song duration and the number of syllables. Gray-headed Buntings sang various syllable types. We found that a male produced more constant syllables in anterior group than those in posterior group. Males sang distinctive syllables among them. Some syllable types which were frequently appeared in an anterior group. In these analyses, we suggest that the anterior groups in songs of a Gray-headed Bunting express the constant information and the posterior groups contribute to situational communication.

This study compared pitch range, total duration of utterances, pause, boundary tones and mean duration of intonation final syllables of 4 sentences produced by 5 transgenders (male to female) to those of twenty normal adults. Voice analysis was performed by Praat (version 4.049). The results showed that there were differences in pitch range, total duration of utterances, pause, boundary tones and mean duration of intonation final syllables among the 3 groups(transgenders, normal males and normal females).
