본 연구의 목적은 음성의 청지각적 평가도구(GRBAS)와 음성관련 삶의 질(K-VRQOL) 척도를 통해 합창활동에 참여하는 여성 노인의 음성 특성과 음성관련 삶의 질을 비교하는 것이다. 연구 대상은 서울 및 부산 소재의 합창단에서 활동 중인 만 60세 이상의 여성 노인으로 총 77명이었다. 합창단은 참여 유형에 따라 합창단(Regular choir)과 찬양단(Church choir) 두 개의 집단으로 분류하였다. 청지각적 음성평가는 /a/ 모음을 발성하는 음성을 듣고 전문가가 청지각적 평가(GRBAS) 척도를 사용하여 평정하였다. 연구 결과, 합창활동 참여 유형에 따라 집단 간 차이를 비교했을 때 찬양단에서 활동하는 여성 노인에 비해 합창단에서 활동하는 여성 노인의 경우 주관적 음성 인식 수준에서 대화 시 음성 사용 만족도가 높은 것으로 나타났다. 또한, 음성관련 삶의 질(K-VRQOL) 척도의 신체 기능 영역에 해당하는 문항에서 만족도가 높은 것으로 분석되었다. 본 연구는 합창활동이 노년기 음성기능의 개선뿐 아니라 음성사용의 주관적 인식 수준을 향상시키는데 긍정적인 결과를 기대할 수 있을 것이라는 점을 확인하였으며, 노인 음성개선을 위한 체계적인 음악 중재 프로그램의 필요성을 시사하고 있다.

Electroglottography (EGG) is a common method for providing non-invasive measurements of glottal activity. EGG has been used in vocal pathology as a clinical or research tool to measure vocal fold contact. This paper presents the results of pitch, jitter, and closed quotient (CQ) measurements in electroglottographic signals of young (mean = 22.7 years) and elderly (mean = 74.3 years) male and female subjects. The sustained corner vowels /i/, /a/, and /u/ were measured at around 70 dB SPL since the most notable among EGG variables is the phonation intensity, which showed positive correlation with closed phase. The aim of this paper was to measure EGG data according to age and gender. In CQ, there was a significant difference between young and elderly female subjects while there was no significant difference between young and elderly male subjects. The mean value for young males was higher than that for elderly males while the mean value for young females was lower than that for elderly females. Thus, it can be said that in mean values, increased CQ was related to decreased age for females, while CQ decreased for males as the speaker's age decreased. Although the laryngeal degeneration due to increased age seems to occur to a lesser extent in females, the significant increase of CQ in elderly female voices could not be explained in terms of age-related physiological changes. In standard deviation of pitch and jitter, the mean values for young and elderly males were higher than that for young and elderly females. That is, male subjects showed higher in mean values of voice variables than female subjects. This result could be considered as a sign of vocal instability in males. It was suggested that these results may provide powerful insights into the control and regulation of normal phonation and into the detection and characterization of pathology.

Larynx plays an important role in phonation and protection of the respiratory tract during swallowing. The reduced anatomical and physiological function in elevation of larynx and glottis closure can cause problems in voice and swallowing. The present study investigated the Korean version of handicap index of dysphagia in elderly Koreans. Therefore, 60 normal elderly Koreans ranged from 65 to 95 and 20 normal Korean young adults aged from 20 to 25 were participated in this study to compare total (T), physical (P), functional (F), and emotional (E) index scores between two groups as well as among sub groups (60s, 70s, 80s) in elderly. For swallowing, total and sub dysphagia handicap index (DHI) scores, voice quality during /a/phonation following swallowing (saliva and water), intensity of coughing, and L-DDK were measured. The results showed that functional (P), physical (P), emotional (E) scores as well as total (T) score were significantly different between young adults and old adults in DHI(p<.05). Additionally, there was a negative correlation between total DHI score and intensity of coughing (r=-.51) as well as L-DDK (r=-.70). These findings suggest that a slow rate in vocal fold adduction and reduced intensity of coughing in the elderly affect swallowing function. Thus, recently translated Korean version of DHI may be useful as supplement in evaluating the swallowing problems in elderly people.

나이가 들면서 발생하는 음성 문제는 사회적, 정서적으로 영향을 미칠 수 있으며, 나아가 고립감과 우울증으로 이어질 수 있다. 이에 본 연구에서는 노화로 인한 음향학적 특성 변화를 음질과 구어 유창성의 변화를 알아보고자 한다. 이를 위해 노년층 남성 20명과 청년층 남성 20명이 산출한 연장발성과 구절 읽기 과제를 녹음하여 분석하였다. 음질 분석 변수로 기본주파수(F0), 주기 변동률(jitter), 진폭 변동률(shimmer), 켑스트럼 정점(cepstral peak prominence, CPP) 값을 분석하였으며 구어 유창성 분석 변수로는 평균 음절 길이(average syllable duration, ASD), 조음 속도(articulation rate, AR), 구어 속도(SR)를 분석하였다. 연구결과, 음질 측정에서 노년층의 경우 F0가 높게 나타났으며 jitter, shimmer, CPP의 결과값을 통해 음질이 저하된 것으로 나타났다. 구어 유창성 분석 결과, 노년층은 ASD, AR, SR의 결과값을 통해 느리게 발화하는 것으로 나타났다. 음질과 구어유창성 간 상관관계 분석 결과, shimmer와 CPP 값과 각각 ASD와 SR에서 높은 상관관계가 나타났다. 본 연구결과를 통해 노화에 따른 음성과 구어 유창성 변화를 조기에 발견하고 이에 대한 적절한 훈련법을 제공할 수 있을 것으로 기대된다.

Multiple physical changes of the larynx and its components occur with age. Vocal pitch, commonly expressed through measures of fundamental frequency (Fo) relate to physical conditions of the larynx. Available data is lacking for the senescent voice, and should be applied to the of changes of elderly speakers' Fo characteristics. The purpose of this study was to investigate the Fo of normal elderly speaker's voice. A total of 406 normal elderly speakers (207 males and 199 females) participated in this experiment. Age ranged from 60 years to 89 years. The subjects were asked to produce sustained corner vowels (/a/ /i/ /u/) three times each and the data were analyzed using the MDVP of CSL. According to the results of this study, the mean Fo from the ages of 60's to 80's shows 143.95Hz(SD 13.94) for men and 185.42Hz (SD 15.29) for women. For men, a significant change is found as a function of age in the Fo (F=16.181, p<.05). A post-hoc Scheffe test revealed significant differences between the Fo data of subjects aged 60's and 70's, 60's and 80's. For women, a significant change is found as a function of age in the Fo (F=49.013, p<.05). A post-hoc $Scheff'{e}$ test revealed significant differences between the Fo data of subjects in their 60's and 70's, 70's and 80's, 60's and 80's. The Fo of men goes up from their 60's to 80's gradually, whereas the Fo of women goes down gradually until their 70's, and after their 70's it again increases. It has been known that diminishing estrogen levels in women in old age may be a factor in lowering Fo, whereas diminishing testosterone levels in men may contribute to a rising Fo. This result may be used as some meaningful guideline and lead the basic data to differentiate between normal aged voice and aged voice disorders.

In this paper, the research and development aim to strengthen the digital accessibility of the elderly by developing a kiosk incorporating AI voice recognition technology that can replace the promotional signage currently being installed and spread in the elderly and social welfare centers most frequently used by the digital underprivileged. It was intended to develop a converged system for the use of bulletin board functions, educational functions, and welfare center facilities, and to seek ways to increase the user's digital device experience through direct experience and education. Through interviews and surveys of senior citizens and social welfare centers, it was intended to collect problems and pain Points that the elderly currently experience in the process of using kiosks and apply them to the development process, and improve problems through pilot services. Through this study, it was confirmed that voice recognition technology is 2 to 6 times faster than keyboard input, so it is helpful for the elderly who are not familiar with device operation. However, it is necessary to improve the problem that there is a difference in the accuracy of the recognition rate according to the surrounding environment with noise. Through small efforts such as this study, we hope that the elderly will be a little free from digital alienation.
