This study was performed to compare the aerodynamic characteristics of young and elderly adult male patients with voice disorders during continuous speech. Aerodynamic measurements were obtained after 12 young male patients and 9 elderly male patients read a paragraph. The elderly group showed longer duration, lower airflow rate and air volume than the younger group, but the differences were not significant except phonation time. So, when interpreting the meaning of aerodynamic measures of elderly voice disorder patients in the aspects of airflow and air volume, it should take into account various conditions(e. g. reading materials, pulmonary functions) as well as age.

The purpose of this study is to find out how voice recognition technology can be utilized to solve the elderly problem rapidly aging in Korea. Public support services and civilian nursing services for the elderly are expected to expand in Korea. In this case, voice recognition technology can be used variously for the elderly who are not familiar with the media interface. To this end, our researchers visited Japan and examined the achievements obtained by voice recognition technology in the elderly care. Especially, when caregivers write reports, they have greatly reduced their working hours by replacing the handwritten reports with ones using voice recognition technology. This method can be easily implemented in Korea. In addition, the social cost of the elderly support can be gradually reduced through the development of a robot equipped with voice recognition technology. Consequently, we realize that when voice recognition technology is combined with artificial intelligence programs of various emotion recognition functions and various policy possibilities as well.

일반인들은 음성인식을 이용한 생활보조기구들의 필요성이 적지만 장애인이나 노인들은 가족이나 주변인의 도움을 받지 않고서는 가전제품의 작동이나 전화통화 등과 같은 일을 스스로 하기에는 쉽지 않다. 이러한 사람들에게 각 가정에 널리 보급되어 있는 PC를 이용하여서 타인의 도움을 받지 않고서도 간편하게 사용할 수 있게 음성을 이용한 생활보조기구들 제어에 응용하였다본 음성인식기는 음성의 끝점 검출, 음성의 특징계수 추출, 백터 양자화 학습 및 인식, HMM학습 그리고 HMM인식으로 나누어져 있다. 그리고 그 인식 결과에 따라 생활보조기구등을 제어하였다. 이러한 음성인식기를 만드는 것은 노인이나 장애인들에게 자신이 혼자할수 없는 생활의 편리함을가져다 주기 위함이고 일반정상인에게도 많은 편리함을 가져다 주기 위함이다. 그러나 언어 학습과정에서 노인이나 환자는 학습에 어려움이 있어 적은 학습으로도 인식되어야하는 과제가 남아있다.

Speech recognition is one of the areas actively commercialized using deep learning and machine learning techniques. However, the majority of speech recognition systems on the market are developed on data with limited diversity of speakers and tend to perform well on typical adult speakers only. This is because most of the speech recognition models are generally learned using a speech database obtained from adult males and females. This tends to cause problems in recognizing the speech of the elderly, children and people with dialects well. To solve these problems, it may be necessary to retain big database or to collect a data for applying a speaker adaptation. However, this paper proposes that a new end-to-end speech recognition method consists of an acoustic augmented recurrent encoder and a transformer decoder with linguistic prediction. The proposed method can bring about the reliable performance of acoustic and language models in limited data conditions. The proposed method was evaluated to recognize Korean elderly and children speech with limited amount of training data and showed the better performance compared of a conventional method.

The purpose of this study is to review systematically the literatures on the research of the elderly speech signal processing based on the domestic gender innovation and to introduce the utility and innovation of the gender analysis methods. From 2000 to present, among the 37 research papers published in the Korean Journal, 25 papers were selected according to the inclusion and exclusion criteria. And gender analysis methods were applied to gender research subject and design. Research results show diversity of research field and high gender recognition of R & D team are needed in research and development of engineering of gender innovation perspective. In addition, government-level regulation and research funding should be systematically applied to gender innovation research processes in the elderly voice signal processing and various gender innovation projects. In the future gender innovation in the elderly speech signal processing can contribute to the creation of a new market by developing a voice recognition system and service that reflects the needs of both men and women.

최근 장애인들의 사회참여가 점점 늘어나고 있는 상황에서 장애인들에 대한 관심과 권리보호에 대한 사회적인 관심이 높아지고 있다. 우리나라의 경우 국민들의 생활 및 의식수준이 높아지고, 사회복지 및 사회안전망에 대한 관심이 증가하면서 장애인들의 복지 문제가 중요한 이슈로 대두되고 있으며, 세계 최고 수준의 IT기술을 활용하여 장애인들의 복지를 향상하는 방안이 적극적으로 전개되고 있다. 이에 한나라당 김소남 의원은 시각장애인, 노인 등을 위해 문자를 음성으로 출력할 수 있도록 인쇄물 등에 도형 형태로 표시하는 '음성변환용 바코드' 정의를 규정하고, 이를 지원하는 것을 골자로 하는 장애인.노인.임산부 등의 편의증진보장에 관한 법률 개정안을 지난 7월 24일 대표 발의했다. 이와 관련 음성변환용 바코드의 대해 알아보았다.

Background and Objectives : Voice disorder is recognized as a major problem because it negatively affects the elderly's social participation and quality of life. The purpose of this study was to examine the validity and reliability of Korean aging voice index (KAVI), which assesses the quality of life related to the voice of the elderly. Materials and Method : This study was conducted on 211 elderly people aged 65 years or older : 111 patients with voice disorder (mean age 69.8, range 65-80 years) and 100 nomorphonic participants (mean age 70.6, range 65-82 years). Aging voice index was translated into Korean and used and Korean voice-related quality of life (KVQOL) was conducted to verify KAVI. The validity (item validity, concurrent validity, and construct validity) and reliability (test-retest reliability and internal consistency reliability) of KAVI. Results : The item validity (ICC=0.895) and construct validity (r=0.765) showed a high correlation, respectively. And concurrent validity (r=0.748), test-retest reliability (0.851), and internal consistency reliability (${\alpha}=0.832$) were statistically significant in voice disorder group. In addition, there was a significant difference between the voice disorder and the nomorphonic group in AVI total score. Conclusion : KAVI is a validated and reliable quality of life tool that will be useful for assessing the presence and effectiveness of interventions in clinical settings.

우리나라의 노인자살률은 OECD 국가 중에 1위이다. 인위적 고독사인 '자살'의 가장 큰 원인인 우울증을 의사소통을 통해 예방하고자 한다. 본 논문에서는 상황에 따라 독거노인에게 스피커가 먼저 질문하는 형식인 시스템을 제안한다. 음성인식 시스템인 스피커를 활용하여 독거노인의 의사소통을 증대시키고, 질문뿐만이 아니라 식사 여부, 약 복용 여부 관련 일상 알람도 주기 때문에 규칙적인 생활을 하는 데 도움을 준다.
