  • Patent number: 9405504
    Abstract: An information communication terminal includes the followings. An input receiving unit receives an input from a user. A communication unit obtains presentation information corresponding to an input by the user from a server according to a dialog scenario, every time the input is received. A dialog processing unit presents the user with the presentation information obtained by the communication unit. A communication state determination unit determines a communication state between the communication unit and the server. When the communication state determination unit makes a first determination that the communication is deteriorated during a dialog, the dialog processing unit causes the communication unit to obtain, as candidate presentation information, at least one presentation information with a possibility of being presented to the user after the first determination according to the dialog scenario.

  • Patent number: 9257125
    Abstract: An audio frame timing correction method and a wireless device are provided. A controller generates a reference clock for audio coding/decoding such that the reference clock runs fast and moved forward within an audio data sampling interval with the remaining time becoming a margin of the interval. An audio codec decodes demodulated data based on the reference clock, and codes an audio signal based on the reference clock. A demodulator detects wireless frame deviation and determines an adjustment timing whereat the wireless frame symbol timing and the audio frame timing are corrected based on the deviation and the margin. Upon the adjustment timing, the controller synchronizes audio sampling timing with the wireless frame symbol timing.
