Abstract (in Japanese) (See Japanese page) 
(in English) With the aim of making speech easier to listen to on a TV receiver. We are researching effective ways of combining speech enhancement techniques and background sound suppression techniques so as to adapt to the characteristics of the sound in programs and perform gain-control only on the speechless intervals. The preparatory evaluation tests confirm that it is possible to 6dB reduce program background volume by the proposed method. The results of evaluation tests using broadcast-program sound showed that a prototype device was able to adjust a suitable level of background sound for elderly people.
