주관적 문장이란 주관적인 내용을 포함한 문장으로써 저자의 제품이나 사건에 대한 생각을 알 수 있다. 주관적 내용임을 나타내는 주관적인 표현은 문장 전반적으로 골고루 나타날 수도 있지만 일부 한정된 영역에서만 발견될 수도 있다. 따라서 보다 정확한 분류를 위해서는, 문장 전체를 고려하는 정보 외에 사실이나 감정을 표현하는 주관적 혹은 객관적 표현구 정보의 활용이 필요하다. 본 연구에서는 문장 전체를 이용한 분류 결과와 감정 표현구를 이용한 분류 결과를 결합하여 주/객관적 문장 분류기의 성능을 향상시키는 방법을 제안한다. 한 문장은 여러 개의 표현구를 가질 수 있어 복수개의 표현구 단위 결과를 얻게 되며 기계 학습을 응용하여 문장 단위 결과와 결합한다. 실험을 통한 결과, 표현구 단위 결과물 중 최대값을 가지는 두 가지 결과와 문장 전체를 이용한 결과를 합침으로써 2.5% 성능 향상된 79.7%의 정확률을 얻을 수 있었다.

The problem of the sentence-based pronunciation evaluation task is defined in the context of subjective criteria. Three subjective criteria (that is, the minimum subjective word score, the mean subjective word score, and first impression) are proposed and modeled with the combination of word-based assessment. Then, the subjective criteria are approximated with objective sentence pronunciation scores obtained with the combination of word-based metrics. No a priori studies of common mistakes are required, and class-based language models are used to incorporate incorrect and correct pronunciations. Incorrect pronunciations are automatically incorporated by making use of a competitive lexicon and the phonetic rules of students' mother and target languages. This procedure is applicable to any second language learning context, and subjective-objective sentence score correlations greater than or equal to 0.5 can be achieved when the proposed sentence-based pronunciation criteria are approximated with combinations of word-based scores. Finally, the subjective-objective sentence score correlations reported here are very comparable with those published elsewhere resulting from methods that require a priori studies of pronunciation errors.

This study has two main purposes. One is to explore the relationship between syntactic aspects and prosodic aspects in Standard Korean. The other is to provide speech synthesis with the information about such relationship. This study will focus on the prosodic behavior of subjective particles'-i/-ga', '-eun/-neun'. The prosodic features of subjective particles are described respectively. How do the elements such as the position of particles in a sentence, the sentence constituents, the length of the sentence and the rhythmic boundaries influence on the prosodic behavior are also investigated.

In this paper, we presented the prosody analysis results of five selected words according to its usage in a sentence, i.e.. the part of sentence (PoS) while changing the type of sentences such as simple, conjugate, and complex sentences. The selected five Korean words were 'U-Ri-Na-Ra' 'Bul-Kuk-Sa', 'Uh-Muh-Ni', 'Han-Ra-San', and 'Cang-A-Ji'. These five words were used as a subjective, an objective, and an adverb in each simple, conjugate, and complex sentence. The pitch, energy, and duration of each word were then analyzed and used for the synthetic speech prosody Improvement. The subjective test on the prosody improvement showed that more than $50\%$ of our listeners are affirmative to the prosody Improvement of the synthetic speech.

The purpose of this study was to evaluate the maximum and optimal listening speed of Korean TTS for the blind. Five blind participants took part in this study. The instruments used in this study were 17 sentence sets (2 sets for an excercise, 10 sets for a repeated test, and 5 sets for a random test), with short meaningful sentences (the same sentences for the repeated test, different sentences for the random test) with 15 differentiated speeds (Range=0.8-3.6, SD=0.2). Each participant's maximum and quickest listening speeds were calculated by objective recall accuracy (determined by the number of correctly recalled syllables/the total number of syllables in a sentence X 100) and subjective recall accuracy (recall accuracy judged by each participant's subjective evaluation). The results showed that the participants' recall accuracy had a tendency to increase as the TTS speed decreased. Participants' subjective recall accuracy was higher than objective recall accuracy in the repeated tests and vice versa in the random tests. The results also revealed that the participants' sentence familiarity had an influence on their Korean TTS listening speed.

영화 리뷰 사이트에서 영화 평점은 네티즌들의 주관적 판단으로 결정된다. 이로 인해 그들이 남긴 영화평과 평점 사이의 극성이 서로 불일치하는 경우가 종종 발생한다. 본 논문에서는 이 문제를 해결하기 위해 영화의 평가에 영향을 미치는 감성 문장들의 집합을 만들고, 이들을 영화평에 적용하여 평점을 추론한다. 감성 문장들의 집합을 만들기 위한 과정은 감성 어휘 사전을 구축하는 단계와 감성 문장을 구성하는 단계로 이루어진다. 감성 어휘 사전은 영화평에서 쓰인 형용사와 형용사의 극성을 저장한다. 감성 문장은 영화와 관련된 명사를 주어로 갖고 감성 어휘 사전의 어휘를 서술어로 갖는 문장 구조이다. 감성 문장의 극성과 감성 문장에서 쓰인 서술어의 극성이 다른 문장들은 제거하여 감성 문장들이 감성 어휘 사전 어휘의 극성과 일치되도록 하였다. 영화평에서 쓰인 감성 문장들의 평균 점수를 구하면 영화평이 갖는 감성 점수가 된다. 본 연구 결과를 통해 네티즌들이 매긴 평점에 비해 감성 문장 집합을 적용하여 계산한 영화평의 감성 점수가 영화평에 대한 의견을 더 잘 반영한다는 것을 알 수 있다.

Which syntactic function should we assign to the 'ga-type' constituent which occurs in the morphological passive constructions in Korean, [N0-neun N1-i Vpass-ending]? This problem is very important in two respects. First, a small change of status of the particle 'i/ga' can exert an overall influence on the Korean grammar. Second, the particle '-i/ga' cannot guarantee that 'ga-type' constituents are subject of the sentence, so that the concept of syntactic category should be distinguished from that of syntactic function. This paper claims that the analysis of sentence has long been focused on the structure of proposition, namely the argument structure and that the direction of analysis should be turned to the 'person structure' which can be revealed on the pragmatic level. On the basis of this, this paper suggests that the specific type of the morphological passive constructions in Korean, [N0-neun N1-i Vpass-ending] should be analysed in line with the psych-verb constructions and that the modal meaning 'potential' of the passive constructions is correlated with sentence pattern and 'person structure'.

Background and Objectives: Although many studies have evaluated the effect of the digital noise reduction (DNR) algorithm of hearing aids (HAs) on speech recognition, there are few studies on the effect of DNR on music perception. Therefore, we aimed to evaluate the effect of DNR on music, in addition to speech perception, using objective and subjective measurements. Subjects and Methods: Sixteen HA users participated in this study (58.00±10.44 years; 3 males and 13 females). The objective assessment of speech and music perception was based on the Korean version of the Clinical Assessment of Music Perception test and word and sentence recognition scores. Meanwhile, for the subjective assessment, the quality rating of speech and music as well as self-reported HA benefits were evaluated. Results: There was no improvement conferred with DNR of HAs on the objective assessment tests of speech and music perception. The pitch discrimination at 262 Hz in the DNR-off condition was better than that in the unaided condition (p=0.024); however, the unaided condition and the DNR-on conditions did not differ. In the Korean music background questionnaire, responses regarding ease of communication were better in the DNR-on condition than in the DNR-off condition (p=0.029). Conclusions: Speech and music perception or sound quality did not improve with the activation of DNR. However, DNR positively influenced the listener's subjective listening comfort. The DNR-off condition in HAs may be beneficial for pitch discrimination at some frequencies.

Transitive relation and its directionality constitute the precondition for passivization, and the present study purports 10 unearth the true properties of transitivity in connection with the passive phenomena. The bottom line it drives at is this transitivity is a notion that can be best explained in 'cognitive' terms. The original direction of transitivity that is predicated by a verb can be reversed depending on the speaker's intention or the discourse situation. In the imperfective verb constructions transitivity can not be derived from only the content of the sentence itself and the predicate objectionally. That depends on the subjective interpretation of speaker considering the cognitive prototype of human to the various complicated situations.
