This paper aims to propose an intonation labeling method using Momel and to present results of analyzing a speech corpus consisting of 80 passages pronounced by 4 speakers (2 male and 2 female) using the proposed method. The results show that Momel works well enough to derive meaningful pitch targets, which could be labeled with H and L tones. On the other hand, the results of the analysis of Korean speech corpus correspond to earlier work.

이 연구는 담화 표지 '아, 어, 음'의 출현 빈도와 발화 시간, 발화 위치 등을 계량적으로 관찰하여 성별과 연령별 차이를 보이고자 하였다. 이를 위해 대용량 음성 코퍼스인 서울코퍼스를 이용하였고, Praat(ver.6.1.31)으로 음길이와 실제 발화를 확인하고, Emeditor(ver.17.6.1)로 코퍼스를 분석하고, R(ver.3.4.4)로 통계 분석하여 결과를 제시하였다. 성별에 따라 보면 여성의 경우 남성보다 단독 발화에서 '음'이 고빈도로 사용되었고, 발화 종결 위치에서의 평균 음길이 또한 길었다. 연령에 따라 보면 발화 시작 위치에서 10대에서는 '아'가, 40대는 '어'가 고빈도로 출현하는 것이 특징적이었다.

This paper aims to present a taxonomy of non-standard words (NSW) for developing a French text normalization system and to propose a method for evaluating this system based on a corpus. The proposed taxonomy of French NSWs consists of 13 categories, including 2 types of letter-based categories and 9 types of number-based categories. In order to evaluate the text normalization system, a representative test set including NSWs from various text domains, such as news, literature, non-fiction, social-networking services (SNSs), and transcriptions, is constructed, and an evaluation equation is proposed reflecting the distribution of the NSW categories of the target domain to which the system is applied. The error rate of the test set is 1.64%, while the error rate of the whole corpus is 2.08%, reflecting the NSW distribution in the corpus. The results show that the literature and SNS domains are assessed as having higher error rates compared to the test set.

This paper analyzes statistically the relationship between size and balance of text corpus by evaluation of the effect of interview sentences in language model for Korean broadcast news transcription system. Our Korean broadcast news transcription system's ultimate purpose is to recognize not interview speech, but the anchor's and reporter's speech in broadcast news show. But the gathered text corpus for constructing language model consists of interview sentences a portion of the whole, $15\%$ approximately. The characteristic of interview sentence is different from the anchor's and the reporter's in one thing or another. Therefore it disturbs the anchor and reporter oriented language modeling. In this paper, we evaluate the effect of interview sentences in language model for Korean broadcast news transcription system and analyze statistically the relationship between size and balance of text corpus by making an experiment as the same procedure according to varying the size of corpus.

본 논문에서는 114 안내시스템에 저장되어있는 서로 중복되어 있지 않는 1,566,943개의 상호명 코퍼스에서 이 코퍼스의 특징을 가장 잘 표현 해 줄 수 있는 최적 코퍼스를 설계하였다. 최적 코퍼스를 구하기 위해 두 단계의 방식을 택한다. 일 단계는 기본코퍼스에 존재하는 트라이폰이 모두 나타내는 최소의 단어 셋을 구하는 최적 음소균형 코퍼스 셋이고 다음 단계는 기본코퍼스에 존재하는 트라이폰의 빈번도를 고려하는 최소의 단어 셋을 구하는 음소 분포코퍼스 셋을 설계하였다. 실험 결과 최적 음소 균형 셋으로 8,699단어가 선정되었으며 최적 음소 분포 균형 셋으로 16,783 단어가 선정되었다. 이러한 최적 코퍼스는 음성 및 합성 시스템을 위한 음성데이터베이스를 구축 할 때 이용된다.

The present study investigated whether there are differences in articulation rate by gender, age, and individual speakers in a spontaneous speech corpus produced by 40 Seoul Korean speakers. This study measured their articulation rates using a second-per-syllable metric and a syllable-per-second metric. The findings are as follows. First, in spontaneous Seoul Korean speech, there was a gender difference in articulation rates only in age group 10-19, among whom men tended to speak faster than women. Second, individual speakers showed variability in their rates of articulation. The tendency for some speakers to speak faster than others was variable. Finally, there were metric differences in articulation rate. That is, regarding the coefficients of variation, the values of the second-per-syllable metric were much higher than those for the syllable-per-second metric. The articulation rate for the syllable-per-second metric tended to be more distinct among individual speakers. The present results imply that data gathered in a corpus of Seoul Korean spontaneous speech may reflect speaker-specific differences in articulatory movements.

본 논문에서는 형태소 분석 단계에서 발생하는 형태소 모호성을 줄이기 위해서 말뭉치를 이용한 형태소 태깅을 구현한 시스템이다. 형태소 태깅을 위한 말뭉치가 대량의 것이 아니라도 효율적인 품사 분류와 태깅 알고리즘을 가지고 올바르고 효율적인 태깅을 할 수 있도록 하였다. 어절의 올바른 품사 태깅을 위해서 어절들 간의 인접도가 아니라 품사들 간의 인접도, 그리고 품사간의 제약 정보를 추가한 품사의 태깅에 이용을 하였다. 이와 같이 함으로 효율적인 시스템을 구현할 수 있었다.

This paper presents a method of building an exceptional pronunciation dictionary for Korean automatic pronunciation generator. An automatic pronunciation generator is an essential element of speech recognition system and a TTS (Text-To-Speech) system. It is composed of a part of regular rules and an exceptional pronunciation dictionary. The exceptional pronunciation dictionary is created by extracting the words which have exceptional pronunciations from text corpus based on the characteristics of the words of exceptional pronunciation through phonological research and text analysis. Thus, the method contributes to improve performance of Korean automatic pronunciation generator as well as the performance of speech recognition system and TTS system.

The purpose of this study was to measure the first two vowel formants of the forty male and female speakers (twenty young vs. old male speakers and twenty young vs. old female speakers) from the Buckeye Corpus of Conversational Speech and to examine the vowel formant changes across two generations (younger vs. older). The results indicated that the vowel space of the younger generation (in their thirties or less) shifted to the lower left position compared to those of the older generation (in their forties or more) in both male and female speakers. When the results were compared to those of Peterson & Barney (1952), it appears that differences can be found in the size of the vowel spaces through time.

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.
