Research Abstract

Speech signal includes a large amount of privacy information. Removing of the information is necessary for using the general useful information included in the speech signal. We developed speech elimination/speech separation, speech recognition for voice conversion, distant speech recognition techniques as the fundamental techniques for removing the privacy information accurately.
