The purpose of this study was to investigate the syllable and phoneme frequencies in the spontaneous speech of some Korean children. Sixty four normally developing children aged from 2 to 5 were involved (male: female=1 : 1, 16 children in each age group). Fifty connected utterances were analyzed using the KCLA (Korean Computerized Language Analysis) 2.0 and Exel. The findings were as follows: 1) /i/ was the most frequently used syllable and was followed by /yo/, /k/, /s'/, /nen/ and so on. 2) The most frequently used Korean phonemes were syllable-initial consonant /k/, syllable- medial vowel /a/ and syllable-final consonant /n/. 3) All seven syllable final consonants (/p,t,k,m,n,n,l/) were used more frequently in the word-medial position than in the word-final position. Three syllable initial consonants(/k, I, s'/) were used more frequently in the word-medial position than in the word-initial position. The syllable and phoneme frequencies in the Korean children's spontaneous speech will provide valuable information in interpreting the severity of phonological disorder and in developing tools for the Korean phonological assessment and intervention.

The purpose of this paper is to identify the workings of intonation realized in the endings through the spoken language. To achieve this objective, this paper has analyzed 300 minutes of spontaneous speech by women from Seoul and discussed the meanings of modality and their relationship with intonation. Intonation functions significantly in polysemous modal endings in epistemic and act modality. Epistemic modality is usually expressed through indirect and soft intonations such as L:, M: and LH, whereas act modality is expressed through direct and strong intonations such as H, HL and LHL. Intonation appears to be related to the Certainty degree of information, rather than classification of modality, Lengthening relate to indirectness, H with uncertainty, L with statements or affirmation, and HL and LHL relates to assertive attitude. This paper is significant as it has overcome the abstractness of existing modality studies and has engaged in objective and comprehensive analysis with actual spontaneous speech data.

The aim of this paper is to study the morphemization of {Geuraegajigo} based on a spontaneous speech corpus. For this purpose, the distributions, the semantic functions, and the intonational phrase pattterns of the connective {Geuraegajigo} have been analyzed based on the corpus. The results are as follow; at first, coalescence that comes with a morphemization process was found, resulting in many variations. Secondly, there are three functions of it: [Direct/Indirect interrelationship], [Enumerate conjunction], and [Discourse marker]. And this semantic/functional diversity has many similarities with conjunctive adverbs. Lastly, intonational phrase patterns of {Geuraegajigo} accord with those of conjunctive adverbs. Especially, the discourse strategic IP pattern is connected with the short variation type. In conclusion, {Geuraegajigo} has finished turning into a conjunctive adverb through morphemization.

The purpose of this work is to examine the voice onset times(VOTs) of the voiceless and voiced stops from the ten young male speakers of the Buckeye corpus[9]. The factors that are known to affect VOTs were also extracted, including the place of articulation, height of following vowels, location within word, presence of a preceding [s], status of the target word with respect to the content versus function word, presence of a syllabic stress, word frequency and speech rate. Findings from this work mostly agreed with those from earlier studies on English, but with some exceptions and new discoveries. We hope that this work can contribute to figuring out the nature and properties of the spontaneous speech of English.

The limited capacity model has been used to explain linguistic interactions and trade-offs that occur in children's speech. The purpose of the present investigation is to explore the interrelationship of MLU (as an index of syntactic development) and fluency in the spontaneous speech of normal children. Twenty normal children's (ten girls and ten boys, aged 36-48 months) spontaneous speech samples were obtained during free-play interactions with their mothers or other adults. The results indicated that the MLU of disfluent utterances were significantly longer than that of fluent utterances. Also, disfluencies occurred more frequently in longer utterances than in shorter utterances. In addition, the utterances where disfluencies occurred more than 2 times were longer than those where disfluencies occurred once. These results imply that the increase of MLU appear to affect not only the occurrence of disfluent utterances, but also the number of disfluencies within the utterances. In other' words, these findings show that there are trade-off effects between MLU and fluency. This is discussed within a limited capacity framework.

The purpose of this study was to determine the effects of associative drawing task in a Korean bilingual aphasic. The subject is a 41-year old male and lived and was educated in the United States for over 25 years(from the age of 14 through 39). His former occupation was a psychiatrist. He has had a massive lesion in the occipital lobe. This study focused on improving his spontaneous language performances by associative drawing task. The associative drawing task along with spontaneous speech is to help the subject's cognition. The ten target words in this treatment were familiar words and could be drawn easily. The results were that the associative drawing task was effective on improving the patient's drawing ability-writing ability in English only-and naming performance both in English and Korean. However, the patient's writing ability in Korean did not show any improvement.

The present study examines the degree of suffix reduction that occurs when the Korean suffix [-nɨn] was attached to the root in spontaneous Seoul Korean speech. Specifically, it focuses on the degrees of reduction produced by individual speakers. The degree of reduction was assessed as the duration of the suffix [-nɨn] to clarify the continuum between the full and reduced forms. The results revealed that, first, the reduced forms of the suffix [-nɨn] were significantly distinguished from the full forms in the suffixation processes. Second, regarding parts of speech, the differences among individual speakers on the degrees of reduction were clearer when the suffix [-nɨn] was attached to verbs, rather than nouns and pronouns. Finally, the length of a root played a critical role in determining the degree of reduction of the suffix [-nɨn]. The degrees of reduction for individual speakers significantly differed when the suffix [-nɨn] was attached to two-syllable roots than three- and four-syllable roots. In conclusion, individual differences in the degrees of reduction were likely to occur when the roots are verbs and when two-syllable roots.

The aim of this paper is to investigate the development of inflected words of Korean based on the analysis of 3 to 8 year-old children's spontaneous speech. For this purpose, the authors transcribe the spontaneous speech of 10 Korean children for each age and classified inflected word. The result of the analysis is as follows : $\circled1$ In the verbs simple words are occupied 62％, derivative words 18％ and complex words 20％. In the adjectives simple words are 82％, derivative words 7％ and complex words 11％. $\circled2$ The children's getting older, derivative and complex words are increased, in spite of simple words are reduced. $\circled3$ 4 year-old children get to start the ability of word formation and then since the children become 8 year-old, the children complete that ability almost all we think.

In this paper, we propose a style-specific language model adaptation scheme using n-gram based tf*idf similarity for Korean spontaneous speech recognition. Korean spontaneous speech shows especially different style-specific characteristics such as filled pauses, word omission, and contraction, which are related to function words and depend on preceding or following words. To reflect these style-specific characteristics and overcome insufficient data for training language model, we estimate in-domain dependent n-gram model by relevance weighting of out-of-domain text data according to their n-. gram based tf*idf similarity, in which in-domain language model include disfluency model. Recognition results show that n-gram based tf*idf similarity weighting effectively reflects style difference.
