This paper presents a system which recognizes the Korean Sign Language(KSL) and translates into normal Korean speech. A sign language is a method of communication for the deaf-mute who uses gestures, especially both hands and fingers. Since the human hands and fingers are not the same in physical dimension, the same form of a gesture produced by two signers with their hands may not produce the same numerical values when obtained through electronic sensors. In this paper, we propose a dynamic gesture recognition method based on feature analysis for efficient classification of hand motions, and on a fuzzy min-max neural network for on-line pattern recognition.

The sign language is a method of communication for deaf person. For sign communication, sign language and manual alphabet are used continuously. In this paper is proposed a system which recognize Korean sign language(KSL) and Korean manual alphabet(KMA) continuously. For recognizing KSL and KMA, basic elements for sign language, namely, the 14 hand directions, 23 hand postures, and 14 hand orientations are used. At first, this system recognize current motion state using speed and change of speed in motion by state automata. Using state, basic element classifiers using Fuzzy Min-Max Neural Network and Fuzzy Rule are executed. Meaning of signed gesture is selected by using basic elements which was recognized.

디지털화와 기술의 급격한 발전으로 방송 서비스도 고품질 서비스를 보다 편리하게 이용할 수 있도록 진화하고 있다. 이러한 변화하는 방송 환경에서 비장애인 대비 소외계층의 정보 접근성을 높이기 위한 연구에 대한 필요성이 증가하고 있다. 이러한 연구의 일환으로 UHD 자막 방송 서비스를 개선하기 위한 연구인 '감성표현 자막 서비스 기술' 연구를 진행하였다. 감성표현 자막 서비스 기술은 단순한 텍스트의 전달이 아닌 이미지와 폰트 스타일을 포함한 다양한 시각적 표현을 통해 청각장애인의 방송 내용에 대한 이해도를 향상시키기 위한 기술이다. 본 논문에서는 이러한 감성표현 자막 서비스를 소개하고 해당 서비스를 가능하게 하는 관련 기술과 시스템 구현 결과에 대하여 다룬다. 지상파 UHD 방송을 대상으로 개선된 형태의 자막 서비스를 제공하기 위한 핵심 시스템인 감성자막 편집기를 개발하였다. 감성자막 편집기는 화자의 감정 정보 등을 입력, 편집하고 편집된 감성자막을 영상과 싱크를 맞추어 재생하는 기술과 감성자막을 UHD 송출시스템으로 전송하는 시스템이다.

방송의 디지털화에 따른 비장애인 대비 소외 계층의 정보 접근성의 부족은 소외 계층에 대한 정보 격차를 심화시킬 수 있다. 이에 캐릭터 수화 방송, 자막 방송 등 장애인을 위한 방송 서비스의 양적, 질적 개선에 관한 연구가 진행되고 있다. 자막 방송 서비스의 경우, 관련 법령에 따라 서비스를 실시하고 있으며 지상파 UHD 방송의 경우에도 본 방송을 시작한 이래 폐쇄 자막 서비스 시스템을 구축하여 서비스를 제공하고 있다. 이러한 기존 자막 서비스는 텍스트 형태의 단조로운 내용 전달 방식이어서 다양한 스타일로 풍부하게 내용을 전달하는 것에 대한 요구가 있다. 이에 본 논문에서는 지상파 UHD 방송을 대상으로 개선된 형태의 자막 서비스인 감성자막 서비스를 소개하고 이를 위한 감성 자막 편집기 기술 개발에 대하여 다룬다. 감성자막 서비스는 화자의 감정 정보를 자막 메타데이터에 추가적으로 제공하여, 감정에 따라 다양한 이모티콘이나 다른 종류의 폰트 스타일로 자막 서비스가 가능하게 하는 서비스이다. 감성자막 편집기는 이러한 감성 자막 메타데이터를 추가, 편집하고 감성자막 파일로 생성하기 위한 시스템으로, 지상파 UHD 송출 시스템 및 폐쇄 자막 표준을 고려하여 개발하였다.

본 논문에서는 딥러닝 소리 인식을 이용하여 실내에서 발생할 수 있는 다양한 소리를 시각적인 정보로 제공해주는 스마트허브 시스템을 제안한다. 인공지능 모델은 2D-CNN 구조를 활용하여 학습을 진행하였고, 스마트허브 하드웨어는 라즈베리파이를 이용하여 구현하였다. 제안된 시스템은 청각장애인을 위해 설계된 다양한 청각 정보를 시각 정보로 전달하는 다양한 제품을 하나로 대체할 수 있을 뿐만 아니라, 설치 및 운반이 간편하여 누구나 사용하기 쉬워서 활용도가 높을 것으로 기대된다.

Two types of speech signal processores (SSP) for cochlea prosthesis are designed. One is designed using cochlear model and the other is designed using Information (formant, pitch, intensity) extraction method. For these, cochlear model and acoustic information extraction method are proposed. The result shows SSP of cochlear model type contain more acoustic cues than that of information extraction type.

The purpose of the present study was to investigate the effectiveness of self-monitoring on spontaneously initiating speech behavior of the hearing-impaired preschoolers. Three hearing-impaired preschoolers were selected from a special school for the deaf. They showed some vocalizations and words under intensive instruction settings, but never spontaneously spoke as a means of communication. Multiple probe design was applied in this study. During the self-monitoring intervention, each child was trained to assess whether his own initiating speech behavior was occurred or not, and then record his own behavior's occurrence on the self-recording sheets and self-graphing sheets. The vibration of handphone was used as a tactile cue for self-monitoring. The results of the present study were as follows: (1) self-monitoring significantly increased the percentage of occurrence of spontaneously initiating speech behaviors. (2) Increased level of spontaneously initiating speech behavior were generalized into another natural instruction (cognitive) settings. (3) Increased level of spontaneously initiating speech behavior were maintained after four weeks from the termination of the intervention.

Frequency transposition (FT) hearing system was designed for individuals with little or no residual hearing at high frequencies. This device compresses and shifts the wide-band, high frequency acoustic energy where important features for speech perception are concentrated to the audible, lower range of frequencies. The usefulness of the FT system was investigated for 12 patients (7 children and 5 adults) with severe-to-profound sensorineural hearing losses compared with conventional hearing aids. Results suggest that the hearing impaired can benefit from the FT system with appropriate selection criteria and auditory (re)habilitation program.

Finger language is a typical tool for deaf persons. But learning the finger language for non-handicapped persons is very difficult. To overcome these difficulties, a new communication method using visual function is developed recently. Even though the developed system uses the visual function, it needs expensive equipments such as camera and computer. To be used in the real environments, the cost of equipments is a critical factor. If the recognition system for the finger language can be developed with low price equipments, the system can be used in the notebook or cellular phone. The image captured by PC camera was processed by preprocessing algorithm. To recognize the finger language, the resulting image was divide into $5{\times}5$ sections. The recognition system uses a similarity method and position information. The simulation results shows the effectiveness of the proposed algorithm.

This study was conducted to determine the effects of horticultural therapy on self-esteem of women with hearing impairment. Ten women with hearing impairment registered in the Mokpo Branch of the Korean Association of the Deaf participated in the horticultural therapy programs (HTP) for self-esteem. The self-esteem scale was used to evaluate the effects of the programs and scores were compared to determine the difference before and after the programs. Self-esteem was improved in all 10 subjects, and its mean value increased with statistical significance from 22.5 points before the programs to 29.8 points after the programs. The programs preferred by women with hearing impairment included 'making a centerpiece using scented candles and flowers', 'packing and planting pot spray chrysanthemum', 'making a topiary', 'planting Hedera helix', and 'planting cyclamen'. Therefore, it was suggested that self-esteem of women with hearing impairment were improved by increasing social and family support, emotional stability, positive feedback, and self-expression through horticultural therapy programs.
