  • Patent number: 7231346
    Abstract: A speech section detection apparatus capable of reliably detecting a speech section even for a word containing a glottal stop sound or for a word containing a succession of “s” column sounds or “h” column sounds (sounds in the third column or the sixth column in the Japanese Goju-on Zu syllabary table). A speech signal detected by a microphone is amplified by a line amplifier, and converted by an analog/digital converter into a digital signal which is then stored in a memory. The stored speech signal is fetched into a pitch detector where a speech pitch is extracted by processing the speech signal in time domain. A gate signal generator controls the gate signal based on the speech pitch, and a speech section signal generator controls a speech section signal based on the gate signal. A word can be extracted by segmenting the speech signal stored in the memory in accordance with the speech section signal.

  • Patent number: 7190415
    Abstract: A digital broadcasting receiver for changing a current channel from one channel to another channel when a commercial message is broadcast on the one channel on which a program is being watched. The time after changing the current channel is measured by a timer IC. When a predetermined time has passed, the current channel is returned to the one channel in response to the operation of a switch or the voice input from a microphone by a user. The program on the one channel is recorded in an RAM so that the program can be reproduced when the user wants to watch the program retroactively. As soon as the predetermined time has passed, an audio output processing section forms a voice message and informs the user of the fact from the speaker so as to draw the attention of the user to the fact.

  • Patent number: 7172833
    Abstract: The present invention discloses an alkaline dry cell with a high capacity having a superior liquid leak resistant property. In this alkaline dry cell, the thickness of the trunk portion of an external can is made thinner than 0.18 mm, and the thickness of the sealing edge portion of the external can is set to not less than 1.4 times the thickness of trunk portion.

  • Publication number: 20050212966
    Abstract: A digital broadcast receiving apparatus for receiving a digital broadcast, includes a freeze determining section and a display control section. The freeze determining section determines whether or not a freeze process should be initiated on a basis of a receiving status of the digital broadcast. The freeze determining section also determines whether or not the free process being performed should be terminated on the basis of a receiving status of the digital broadcast. The display control section initiates the freeze process when the freeze determining section concludes that the freeze process should be initiated. The display control section terminates the freeze process being performed when the freeze determining section concludes that the freeze process being performed should be terminated. The freeze process includes displaying a freeze notification on a screen while changing the freeze notification so that a user recognizes the change of the freeze notification.
