  • Patent number: 10867607
    Abstract: A voice dialog device includes a sight line detection unit configured to detect a sight line of a user, a voice acquiring unit configured to acquire voice pronounced by the user, and a processor. The processor is configured to perform a step of acquiring a result of recognizing the voice, a step of determining whether or not the user is driving, and a step of determining whether or not the voice dialog device has a dialog with the user. When the detected sight line of the user is in a certain direction, and a start keyword has been detected from the voice, the processor determines that the user has started a dialog. The processor switches the certain direction based on whether the user is driving.

  • Publication number: 20200158268
    Abstract: A refrigerant transport hose excellent in both durability and barrier properties is provided. The refrigerant transport hose 10 has a barrier layer formed from a resin composition containing a polymer component as an innermost layer. The polymer component contains a polyamide resin (A) and a polyolefin-based elastomer (B). The innermost layer is to be in direct contact with a refrigerant and an oil flowing in the refrigerant transport hose. The polymer component further contains a block copolymer (C) having a structure in which a polyamide block is grafted to a polyolefin skeleton. The content of the block copolymer (C) is 5 to 45 parts by mass with respect to 100 parts by mass of the polymer component. The total content of the polyolefin-based elastomer (B) and the block copolymer (C) is less than 70 parts by mass with respect to 100 parts by mass of the polymer component. The block copolymer (C) has bimodal melting peaks in differential scanning calorimetry (DSC).

  • Publication number: 20180090132
    Abstract: A voice dialogue system includes a dialogue scenario storage storing a plurality of dialogue scenarios and a dialogue text generator generating a dialogue text for responding to a user utterance based on a result of voice recognition. The dialogue scenario is a single set of three contents: a content of a first system utterance, a content of an expected user utterance, and a content of a second system utterance for responding to the expected user utterance. The dialogue text generator determines whether or not the user utterance is an expected response and, when the user utterance is an expected response, generates a second system utterance defined in a dialogue scenario as a response to the user utterance as a dialogue text for responding to the user utterance.
