AUTOMATIC EVALUATION SYSTEM OF ENGLISH PRONUNCIATION OF NON-NATIVE SPEAKER AND EVALUATION METHOD USING SAME

Номер: KR1020180137207A
Автор: JANG, TAE YEOUB
Принадлежит:

The present invention relates to an automatic evaluation system of English pronunciation by a software method and an evaluation method using the same. The evaluation system quantitatively compares linguistic features of English with acoustic features extracted from a speech of an English speaking test taker, scores the compared difference, and automatically represents the score. What kind of linguistic feature will be extracted is a technical core in the construction of the automatic evaluation system and the present invention uses features of spoken language related to the speech prosody and fluency of English. The features use a point that a non-native speaker having low proficiency has a huge difference from a native speaker when speaking English due to the interference of his/her native language. The present invention includes: a voice recognition unit which recognizes the speaking of a non-native speaker; a voice column conversion unit which converts the recognized voice into text; ...

CUTTING OIL FEEDING APPARATUS USING PULSATION CONTROL OF PISTON

Номер: KR1020160134333A
Автор: CHANG, TAI YEOB
Принадлежит:

The present invention relates to a cutting oil feeding apparatus using pulsation control of a piston, which enhances cooling efficiency between a workpiece and a cutting tool while minimizing abuse of cutting oil to elongate life of the cutting tool and to enhance process precision. The present invention comprises: a manifold forming an inlet pipe connected to an external cutting oil supply line and an outlet pipe branching off from the inlet pipe to be connected to an external cutting oil discharge line; a single cylinder type engine arranged to face the outlet pipe around the inlet pipe and moving a provided piston backwards and forwards in a pulsation manner to open and close the corresponding outlet pipe; and an ejector unit providing a flow pressure to the cutting oil on the outlet pipe or the cutting oil discharge line by supplying compressed air. The present invention adjusts a supply amount of the cutting oil by actuation of the single cylinder type engine such as abuse of the cutting ...

REMOVAL OF NITROGEN OXIDE AND SULFUR OXIDE

Номер: KR101702831B1
Автор: CHANG, TAI YEOB
Принадлежит: KUMKANG MACHINERY CO., LTD.

The present invention relates to a method and an apparatus for removing nitrogen oxide, which enable nitrogen oxide to be quickly removed at a high rate by using an aqueous solution of sodium chlorite (NaClO_2), which is highly stable at room temperature and easy to handle, instead of using highly reactive chlorine dioxide (ClO_2). The apparatus for removing nitrogen oxide according to the present invention comprises: an ultrasonic atomizer configured to atomize acidified liquid sodium chlorite as a reactant solution; a vapor-phase reaction chamber configured to mix the atomized reactant solution with a sulfur-containing nitrogen oxide stream and to allow the mixture to stay therein; an absorber located above the vapor-phase reaction chamber so as to absorb nitrogen oxide from the mixture moving upward from the vapor-phase reaction chamber.

비원어민의 영어 말하기 발음의 자동평가 시스템 및 이를 이용한 평가방법

Номер: KR0101943520B1

... 본 발명은 영어의 언어적 특성과, 영어 말하기 시험 응시자의 발화에서 추출한 음향 특성(acoustic feature)을 정량적으로 비교하여 그 차이를 점수화하고 자동으로 제시하는 소프트웨어적 방법에 의한 영어 말하기 발음 자동평가 시스템 및 이를 이용한 평가방법에 관한 것이다. 어떠한 언어적 특징을 추출할 것인지가 자동평가 시스템 구축의 기술적 핵심인데, 본 발명에서는 영어의 발화리듬(speech prosody) 및 유창성(fluency)과 관련된 음성언어(spoken language) 특징들을 사용하였다. 이 특징들은 능숙도(proficiency)가 떨어지는 비원어민 화자(non-native speaker)일수록 모국어의 간섭(interference) 등으로 인해 영어 발화시에 원어민 화자의 특징과는 차이가 크게 나타나는 점을 이용하는 것이다.
