In this paper, we investigated the age classification from the speaker by analyzing the voice calls of the emergency center. We classified the adult and elderly from the call center calls using behavioral speech utterances and SVM(Support Vector Machine) which is a machine learning classifier. We selected two behavioral speech utterances through analysis of the call data from the emergency center: Silent Pause and Turn-taking latency. First, the criteria for age classification selected through analysis based on the behavioral speech utterances of the emergency call center and then it was significant(p <0.05) through statistical analysis. We analyzed 200 datasets (adult: 100, elderly: 100) by the 5 fold cross-validation using the SVM(Support Vector Machine) classifier. As a result, we achieved 70% accuracy using two behavioral speech utterances. It is higher accuracy than one behavioral speech utterance. These results can be suggested age classification as a new method which is used behavioral speech utterances and will be classified by combining acoustic information(MFCC) with new behavioral speech utterances of the real voice data in the further work. Furthermore, it will contribute to the development of the emergency situation judgment system related to the age classification.

This study suggested a scheme of revitalization and development of digital talking books(DTB) for the print disable people. In Korea, the number of print disabled people is quickly increasing because of increasing of the acquired blind and the elderly in population. To promote information service and to encourage active participation from the group categorized as print disabled people, library is required two distinctive considerations, design and implementation of authoring tool for DTB and policy and administrative consideration for revitalization for DTB service to the print disable people.

The purpose of this study is to evaluate the prevalence of voice disorders and the Korean voice handicap index in the elderly. For this study, 169 elderly performed two types of questionnaires and vowel /a/ prolongation. Self-reported voice symptoms and the Korean voice handicap index were analyzed and acoustic voice evaluation was performed by MDVP. The results showed that the prevalence of voice disorders in the elderly are significantly higher than that of adults in self-reports. In acoustic evaluation, 32.2% of the male elderly and 40.9% of the female elderly exceeded the thresholds of Jitter (%), Shimmer (%) and NHR. In addition, Korean voice handicap index scores of the female elderly are significantly higher than those of female adults. These findings indicate the high frequency of voice disorders in the elderly and the need to focus on this group. Additional studies on the voice related quality of life for the elderly are needed.

We focused on the care effectiveness of the interactive AI robots. developed an AI toy robot called 'Agaya' to contribute to personalization with more human-centered care. First, by applying P-TTS technology, you can maximize intimacy by autonomously selecting the voice of the person you want to hear. Second, it is possible to heal in your own way with good memory storage and bring back memory function. Third, by having five senses of the role of eyes, nose, mouth, ears, and hands, seeking better personalised services. Fourth, it attempted to develop technologies such as warm temperature maintenance, aroma, sterilization and fine dust removal, convenient charging method. These skills will expand the effective use of interactive robots by elderly people and contribute to building a positive image of the elderly who can plan the remaining old age productively and independently

This study aims to listen to and enjoy sounds using the voice range of the elderly based on VR as voice changes can cause difficulties in communication at ordinary times and lead to elderly people's reluctance or avoidance of social activities.

최근 고령인구와 장애인구에 대한 사회적 배려나 관심이 지속적으로 증가로 인하여 이들에게 실질적인 혜택을 주기위한 기술적 발전과 그에 따른 산업 변화가 일고 있다. 거리에서 쉽게 볼 수 있는 거리의 음성신호를 장착한 신호등에서부터 공중전화, 자동차에 이르기까지 다양하다. 그 중에서 특히 장애인이나 노인들에게 제공되는 정보통신에 대한 시책들은 아직은 미흡하다.

Aging causes a variety of changes in the structure of the vocal fold (VF), resulting in aging-induced dysphonia (presbyphonia). Several studies have investigated the structure of the VF of elderly people from autopsy as well as animal studies. There is an increasing evidence on correlation of structural changes of VF with deteriorated voice in elderly. Although the cellular mechanisms of aging VF have only partially been elucidated, there are many recent advances in biological treatment on aging VF using bioactive molecules such as growth factors. In this study, I'd like to address aging-related structural, biological, and physiological changes in previous literature about human and rodent aging VFs, to provide further insight into the mechanisms responsible for presbyphonia and to translate the basic researches for future clinical trials.

본 연구는 치매노인환자의 생활의 질을 향상시키기 위한 대화시스템의 개발에 목표를 둔다. 제안된 시스템은 주로 세 가지 모듈, 즉, 음성인식, 시간테이블에 의해 구분된 대화 데이터베이스의 자동검색, 그리고 간호사의 녹음음성에 의한 응답 등으로 구성되어 있다. 우선 치매환자가 요양시설에서 자주 발화하는 대화의 내용을 조사하고, 그들의 발화 음성을 인식하고 적절히 응답하도록 구성하였다. 시스템의 평가를 위해서 시스템이 도입되었을 때와 도입되지 않았을 때를 비교, 조사하였다. 시스템이 도입되지 않았을 때는 간호사가 자유로이 케어서비스를 행할 수 있도록 하였다. 비디오 촬영을 통해서 대상자의 행동 및 반응을 조사한 결과, 치매환자의 요구를 충족시키는데 있어서 대화 시스템이 간호사들보다 더 응답적이었다는 것을 알 수 있었다. 게다가, 제안된 시스템은 상호 대화에 있어서 환자가 더 많이 말하도록 유도함을 알 수 있었다.

This study was conducted with the aim of identifying the current state and improvements of the public library services for older adult in Korea. According to the online survey of public libraries in urban areas across the country, a total of 172 libraries responded. Research shows that public libraries generally recognize the importance of elderly users, but there are limitations in active efforts. The priority area for library collection and space/facilities was to be strengthened by the expansion of large type and voice books/periodical books, as well as the need to ask librarians for help to find books in high bookshelves. In the case of library services/programs, the areas that need to be strengthened first were analyzed as social participation programs and humanities programs. The librarians in charge of information services expressed their opinions that more specialized services and programs should be planned and subdivided for the elderly generation in order to provide older adults' services unique to other older adults' service institutions.
