  • Speech processing method and apparatus, storage medium, and speech system
    Patent number: 8065138
    Abstract: A speech processing apparatus includes a spectrum envelope extracting unit which extracts the spectrum envelope of an input speech signal, a spectrum envelope deforming unit which applies deformation to the spectrum envelope to generate a deformed spectrum envelope, a spectrum fine structure extracting unit which extracts the spectrum fine structure of the input speech signal, a deformed spectrum generating unit which generates a deformed spectrum by combining the deformed spectrum envelope with the spectrum fine structure, and a speech generating unit which generates an output speech signal on the basis of the deformed spectrum. This apparatus emits a disrupting sound based on the output speech signal to prevent a third party from eavesdropping on a conversation.
    Type: Grant
    Filed: August 31, 2007
    Date of Patent: November 22, 2011
    Assignees: Japan Advanced Institute of Science and Technology, Glory Ltd.
    Inventors: Masato Akagi, Rieko Futonagane, Yoshihiro Irie, Hisakazu Yanagiuchi, Yoshitane Tanaka
