한혜승(Hyeseung Han),이주경(Joo-Kyeong Lee) 한국음성학회 2007 음성과학 Vol.14 No.4
This paper attempts to verify the theoretical claims in Syntax (Bo?kovi? & Lasnik, 2003; Kim, 1999, 2004) about the phrasing in English that-clauses, presenting an acoustic experiment conducted to observe the patterns of edge tones at the boundaries of that. In the experiment, two different that clauses, complement and relative clauses, were varied in forms (that-retention, that-deletion, adverb insertion before that) and length. Results showed that edge tones, if occurred, mostly showed up before the complement clauses in that-deletion sentences (67%), and that their positions polarized in adverb insertion sentences (56% before that and 44% after that). In the relative clauses, phrasing mostly occurred before that as opposed to after that in that-retention (73%) and adverb insertion sentences (87%). Additionally, phrasing tends to occur more frequently as the sentences get longer. The results suggest that the previous claims based on syntax are not consistent with the results of the current phonetic experiment. This may be interpreted as stating that syntactic boundaries do not always indicate phonetic phrasing, and that there may be some other factors to determine phrasing patterns, for example, rhythmic phrasing operating at the surface level of speech.

Han, Hye-seung, and Joo-Kyeong Lee. 2009. Prosodic features in the English phrases including particles, adverbial prepositions and prepositions. Studies in Phonetics, Phonology and Morphology 15.3. 499-514. This study attempts to investigate prosodic features in the English phrases including particles, (e. g., the second element in a verb phrase such as give up the exam), adverbial prepositions (e. g., the second element of jump off the wall) and prepositions (e.g., the second element of study in the room). A phonetic experiment was conducted to see if there are any differences and /or prosodic structures among those three phrases. The stimuli were varied with two different objects, noun and pronoun and two kinds of rate, slow and fast, and pitch accent distribution and phrasing were measured within the phrases. Results showed that pitch accents were very frequently realized on both the particles and the adverbial prepositions, but that prepositions were rarely implemented a pitch accent. When the objects were a pronoun, a pitch accent consistently moved to particles, adverbial prepositions, and prepositions. Moreover, there are more phrase involved in the boundaries of the particle + the following noun phrase and the preceding verb + adverbial preposition and the adverbial preposition + the following noun phrase. It was interpreted as stating that such patterns reflect the differences in semantic weight among the three elements and the degree of semantic cohesion with the preceding verbs and the following noun phrases, and that adverbial phrases show distinct prosodic features from both particles and prepositions. This suggests that adverbial prepositions should constitute their own category semantically and/or prosaically. (University of Seoul)

정제 알고리즘을 이용한 한국인 화자의 영어 발화 자동 진단 시스템
양일호(Yang IL-Ho),김민석(Kim Min-Seok),유하진(Yu Ha-Jin),한혜승(Han Hyeseung),이주경(Lee Joo-Kyeong) 한국음성학회 2010 말소리와 음성과학 Vol.2 No.2
We propose an automatic pronunciation diagnosis system to evaluate the pronunciation of a foreign language without the uttered text. We recorded English utterances spoken by native and Korean speakers, and utterances spoken by Koreans are evaluated by native speakers based on three criteria: fluency, accuracy of phones and intonation. The system evaluates the utterances of test Korean speakers based on the differences of log-likelihood given two models: one is trained by English speech uttered by native speakers, and the other is trained by English speech uttered by Korean speakers. We also applied purification algorithm to increase class differentiability. The purification can detect and eliminate the non-speech frames such as short pauses, occlusive silences that do not help to discriminate between utterances. As the results, our proposed system has higher correlation with the human scores than the baseline system.

Recently, as electric vehicle technology has become more advanced, V2G (vehicle to grid) technology that uses batteries externally is being commercialized, and is divided into V2H (vehicle to home) and V2B (vehicle to building) depending on the type of grid connection. V2B services have a profit effect by discharging EV energy into the building when the building load is high, maintaining or lowering the buildings base rate, and for this purpose, accurate building load prediction is important. In this study, the results predicted by linear statistical models and nonlinear machine learning models were corrected with a multi-layer perceptron to derive the final results, and were evaluated using one years worth of actual load data on buildings.
