  • Patent number: 8942982
    Abstract: A semiconductor integrated circuit device including: a storage section which temporarily stores a command and text data input from the outside; a speech synthesis section which synthesizes a speech signal corresponding to the text data based on the command and the text data stored in the storage section, and outputs the synthesized speech signal to the outside; and a control section which controls a timing at which the command and the text data stored in the storage section are transferred to the speech synthesis section based on a speech synthesis start control signal. The control section controls an output of a speech output start notification signal which notifies in advance a start of outputting the synthesized speech signal to the outside based on occurrence of a speech synthesis start event, and then controls a start of outputting the synthesized speech signal to the outside at a given timing.

  • Patent number: 8712508
    Abstract: A state detection device includes an acquisition part that acquires an acceleration detection value from an acceleration sensor, and a judgment part that judges a running state or a walking state based on the acceleration detection value. The judgment part detects as to whether a positive/negative sign of the acceleration detection value in a first axis reversed in a predetermined judgment period, determines the running state when the sign reverses, and determines the walking state when the sign does not reverse.

  • Publication number: 20130245987
    Abstract: A state detection device includes an acquisition part that acquires a detected acceleration from an acceleration sensor; an angle information calculation part that calculates, based on a first acceleration vector representing the detected acceleration obtained at a first timing and a second acceleration vector representing the detected acceleration obtained at a second timing, angle information corresponding to an angle defined by the first acceleration vector and the second acceleration vector; and an information acquisition part that acquires movement state information based on the angle information.

  • Publication number: 20080120093
    Abstract: A system for creating a dictionary for speech synthesis is provided. The system has a first dictionary for speech synthesis composed of an aggregation of dictionary data necessary for creating synthesized speech corresponding to an utterance target sentence, and creates, from the first dictionary for speech synthesis, a second dictionary for speech synthesis with a fewer data amount compared to the first dictionary for speech synthesis.

  • Publication number: 20080088617
    Abstract: An electronic display device includes a page data acquisition section which acquires page data including display data and text data, a display data buffer, a write processing section which writes the display data into the display data buffer, a display processing section which displays an image on a display section, and a sound generation section which generates text read-out sound. The display processing section switches display processing between a page batch display process for displaying an image of a given page on the display section and a page split display process for displaying an image of a lower portion of a given page in an upper area of the display section and displaying an image of an upper portion of a subsequent page in a lower area of the display section, based on page break determination information included in the text data and the progress of the text read-out process.
