  • Patent number: 8078460
    Abstract: In a noise suppression apparatus for suppressing noise contained in a speech signal, the speech signal is converted to a first vector of spectral speech components and a second vector of spectral speech components identical to the first vector. A vector of noise suppression coefficients is determined based on the first vector spectral speech components. A vector of estimated noise components is determined based on the first vector spectral speech components, and a speech section correction factor and a nonspeech section correction factor are calculated from the estimated noise components and the first-vector spectral speech components to produce a combined correction factor. The noise suppression coefficients are weighted by the combined correction factor to produce a vector of post-suppression coefficients. The second vector spectral speech components are weighted by the post-suppression coefficients to produce a vector of enhanced speech components.

  • Publication number: 20110255885
    Abstract: A first image forming unit includes a first developing unit that develops a latent image, and a second image forming unit includes a second developing unit that develops a latent image. A transfer unit transfers an image formed by at least one of the first and second image forming units onto a recording medium. A controller performs control to form a transfer image on the recording medium through at least one of a first operation and a second operation. In the first operation, images formed by the first and second image forming units are transferred onto the recording medium as transfer images. In the second operation, the image formed by the first image forming unit is transferred onto the recording medium as a transfer image. A stopping unit stops operation of the second developing unit when the number of transfer images formed through the second operation reaches a preset value.

  • Publication number: 20110196680
    Abstract: When a system (100) is used for synthesizing speech having prosody serving as a reference, the system stores speech element information representing a speech element capable of synthesizing speech having a degree of naturalness indicating a degree of similarity to speech uttered by a human higher than a predetermined reference value (speech element information storage (115)). The system accepts requested prosody information representing prosody requested by the user (requested prosody information accepting part (113)). The system generates intermediate prosody information representing intermediate prosody between the reference prosody and the requested prosody (intermediate prosody information generator (114)). The system executes a speech synthesis process to synthesize speech based on the generated intermediate prosody information and the stored speech element information (speech synthesizer (116)).

  • Publication number: 20110106538
    Abstract: This speech synthesis system includes a server device and a client device. The client device accepts text information representing text, and transmits a speech element request to the server device. The server device stores speech element information. The server device receives the speech element request transmitted by the client device and, in response to the received speech element request, transmits speech element information to the client device so that the speech element information is received by the client device in a different order from an order of arrangement of speech elements in speech corresponding to the text. The client device executes a speech synthesis process by rearranging the speech element information so that speech elements represented by the received speech element information are arranged in the same order as the order of arrangement of the speech elements in the speech corresponding to the text.
