Low-articulation of speech outside the target direction by using multi-point control method
Koichi Nomura, Akitoshi Kataoka (Ryukoku Univ.) EA2011-106
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 change in speech quality.
Therefore, there is a problem of leakage of the contents of speech.
In this report,we propose signal decomposition method by using random vector decomposition and noise-driven decomposition.
We also proposed noise masking method by applying multi-point control method and studied to be the keeping quality of the target direction and low-articulation of speech in the outside the target direction.
We con rmed the low-articulation of speech in outside of target direction.
