| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Multipoint control method is method of playing sound in any direction. Although this method can reduce the sound pressure outside the target direction, there is not signi cant degradation in speech quality. Therefore,there is a problem of leaking of the contents of speech. As the measures, signal decomposition method such asrandom vector decomposition or noise-driven decomposition is proposed. However, these methods are incompatible with keeping speech quality of the target direction and low-articulation of speech in the outside of target direction.In this paper, we propose the residual decomposition method and achieve sound reproduction in the limited area by keeping quality of the target direction and low-articulation in the outside of the target direction. | |
