Interaction between hearing and speaking by aging

Abstract (in Japanese) (See Japanese page) 
(in English) A rapid increase of aged population is one of the social problem. In the aging society, it is difficult for the elderly to establish smooth speech communication. It causes a serious problem in a daily life, because it prevents the elderly from leading a healthy life. Hearing loss is an ordinary phenomenon for the elderly over 70 years old, although they have no subjective symptoms. The hearing loss by aging gradually occurs even in younger generation, and is remarkably confirmed in the high frequency region. The high-frequency hearing loss seriously decreases our ability in hearing consonants of words and sound source separation in noisy environments. Concerning the ability of speech perception, it is possible to roughly estimate the speaker's age, when someone speaks. It suggests that we know some important features, which characterize the elderly speakers, consciously and unconsciously. It has been reported that hoarseness is one of the most important characteristics of the elderly voice. The author has already confirmed that the subjective hoarseness could be caused by the energy lift in the high frequency region. Almost all previous works deal with the problems of the hearing loss by aging and the acoustical deformation of utterance by the elderly individually and independently. In this paper, interaction between hearing and speaking by aging is considered based on the concept of "speech chain."
