  • Publication number: 20140343926
    Abstract: A text in a corpus including a set of world wide web (web) pages is analyzed. At least one word appropriate for a document type set according to a voice recognition target is extracted based on an analysis result. A word set is generated from the extracted at least one word.

  • Publication number: 20140303978
    Abstract: A method and apparatus are provided for automatically acquiring grammar fragments for recognizing and understanding fluently spoken language. Grammar fragments representing a set of syntactically and semantically similar phrases may be generated using three probability distributions: of succeeding words, of preceding words, and of associated call-types. The similarity between phrases may be measured by applying Kullback-Leibler distance to these tree probability distributions. Phrases being close in all three distances may be clustered into a grammar fragment.

  • Patent number: 8684531
    Abstract: An image signal storing unit stores an image signal provided from the outside. An image processing unit appropriately processes the image signal stored in the image signal storing unit in accordance with the instruction from an adjusting unit. A projecting unit projects, onto a display area, light corresponding to an image created by the image processing unit. A display size determination unit computes the display size of the picture plane displayed on a screen based on an image captured by the camera provided adjacent to the projection-type video-image display device. The display size determination unit then determines whether or not the display size of the picture plane is equal to or larger than a predetermined upper-limit size.

  • Patent number: 8585220
    Abstract: Provided is a method of producing an optical element, including: forming a frame portion on a substrate and forming a structural body in a space portion surrounded by the frame portion to thereby form a first optical member; disposing a second optical member on the first optical member in a reduced pressure environment to form an optical element in which the space portion is sealed in a pressure-reduced state; and exposing the optical element to the atmosphere to thereby bring the structural body and the second optical member into close contact with each other by a differential pressure between the atmosphere and the space portion sealed in the pressure-reduced state. Accordingly, it is possible to, when the optical element is bonded, suppress damage to the optical element during the bonding and further improve the function and strength of the optical element without use of an adhesive.

  • Publication number: 20130239042
    Abstract: By detecting position information for a terminal device while an application is running, a range of movement during running can be detected, and the range of movement of the application is recorded and updated as the operation history of each application. Then, when display positions of icons on a display unit are to be changed, it is possible to determine, based on the detected position information, ranges of movement that contain this position information among the recorded ranges of movement. Then, the icons of the applications corresponding to the determined ranges of movement are reflected with priority in changing the display positions.

  • Publication number: 20130098224
    Abstract: Provided are a light emitting control device, computer readable memory device, and method to control a light emitter associated with a pad capable of being struck to produce a sound. In response to detecting a striking of the pad, a tone associated with the pad is produced. A level of the tone produced is determined and a level meter brightness is determined based on the determined level of the tone. An output brightness for the light emitter is calculated associated with the struck pad using the determined level meter brightness and a brightness change pattern. The light emitter associated with the pad is controlled according to the determined output brightness.
