  • Method for recovering target speech based on amplitude distributions of separated signals
    Patent number: 7562013
    Abstract: The present invention provides a method for recovering target speech based on shapes of amplitude distributions of split spectra obtained by use of blind signal separation.
    Type: Grant
    Filed: August 31, 2004
    Date of Patent: July 14, 2009
    Assignee: Kitakyushu Foundation For The Advancement of Industry, Science and Technology
    Inventors: Hiromu Gotanda, Keiichi Kaneda, Takeshi Koya
  • Method for recovering target speech based on speech segment detection under a stationary noise
    Patent number: 7533017
    Abstract: Method for recovering target speech by extracting signal components falling in a speech segment, which is determined based on separated signals obtained through the Independent Component Analysis, thereby minimizing the residual noise in the recovered target speech.
