  • 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: 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.
