CN-121986376-A - Dialogue system for a vehicle

Abstract

A dialog system (1) for a vehicle uses a dialog-type AI (10). A microphone (2) inputs a voice uttered by a driver. A voice recognition unit (41) converts voice input by the microphone (2) into text data. A voice dialogue unit (42) inputs text data converted by a voice recognition unit (41) and text data representing a state of a driver or a vehicle driven by the driver or a command corresponding to the state when the driver utters a voice as input information (S1) to a dialogue AI (10). A speech synthesis unit (43) converts response information (S2) from the dialog type AI (10) into speech. A speaker (5) outputs the voice converted by the voice synthesizing unit (43).

A dialogue system for a vehicle using a dialogue type AI that outputs response information including text data upon receiving input information including the text data, the dialogue system for a vehicle comprising: A voice input unit configured to input voice uttered by a driver; A voice recognition unit configured to convert the voice input by the voice input unit into text data; An input control unit configured to input the text data converted by the voice recognition unit to the dialog AI as the input information together with text data representing a state of the driver or a vehicle driven by the driver when the driver utters a sound or text data of a command corresponding to the state; A speech synthesis unit configured to convert the response information from the dialog type AI into speech, and And a voice output unit configured to output the voice converted by the voice synthesis unit.
2. 2. The dialog system for a vehicle of claim 1, further comprising: A first determination unit configured to determine whether or not a driving load of the driver is high, wherein, In the case where the first determination unit determines that the driving load is high when the driver utters a sound, the input control unit inputs text data for shortening the response information as the text data representing the command to the dialog AI.
3. 3. The dialogue system for a vehicle as claimed in claim 1, wherein, Sensor information from a sensor mounted on the vehicle is input to the input control unit, and The input control unit inputs the sensor information at the time of the driver's utterance to the dialog AI as the state of the vehicle.
4. 4. The dialogue system for a vehicle as claimed in claim 1, wherein, The detection result from an abnormality detection section that detects an abnormality of the vehicle and lights an alarm lamp is input to the input control unit, and The input control unit inputs the detection result of the abnormality detection unit at the time of the driver's utterance to the dialog AI as the state of the vehicle.
5. 5. The dialog system for a vehicle of claim 1, further comprising: an apparatus control unit configured to control a vehicle apparatus, wherein, The input control unit inputs text data representing information about the vehicle device controllable by the device control unit to the dialog type AI, and The device control unit controls the vehicle device based on the text data converted by the voice recognition unit and the response information from the dialog AI.
6. 6. The dialog system for a vehicle of claim 1, further comprising: a second determination unit configured to determine the number of persons in the vehicle, wherein, The input control unit inputs the number of persons determined by the second determination unit to the dialog AI.

Description

Dialogue system for a vehicle Technical Field The present invention relates to a dialogue system for a vehicle. Background A voice proxy service that responds by voice when a user utters a voice has been proposed (patent document 1). The voice proxy service of patent document 1 proposes to return predetermined chat data when the uttered content of the user is not a search. However, in the voice proxy service of patent document 1, since chat data is extracted from predetermined data, a natural response such as a response to talk with a person is not returned. In recent years, a conversational AI (artificial intelligence) has been proposed that is capable of learning from the vast amount of information available on the internet and implementing a more natural conversation, such as ChatGPT. However, such a dialog type AI does not return an appropriate answer unless an appropriate prompt (text data) is entered. For this reason, when the dialog type AI is used in the vehicle, an appropriate response may not be obtained unless the driver speaks the state of the driver, the state of the vehicle, or the like one by one. List of references Patent literature Patent document 1 JP2014-098844A Disclosure of Invention Technical problem The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a dialogue system for a vehicle that appropriately responds to the voice of a driver. Solution to the problem In order to achieve the above object, a dialogue system for a vehicle according to the present invention has the following features. A dialogue system for a vehicle using a dialogue type AI that outputs response information including text data when receiving input information including the text data is provided. The dialogue system for a vehicle includes a voice input unit configured to input voice uttered by a driver, a voice recognition unit configured to convert the voice input by the voice input unit into text data, an input control unit configured to input the text data converted by the voice recognition unit to a dialogue type AI together with text data representing a state of the driver or the vehicle driven by the driver when the driver utters or text data of a command corresponding to the state as input information, a voice synthesis unit configured to convert response information from the dialogue type AI into voice, and a voice output unit configured to output the voice converted by the voice synthesis unit. The beneficial effects of the invention are that According to the present invention, it is possible to provide a dialogue system for a vehicle that appropriately responds to the voice of a driver. The present invention is briefly described above. The details of the present invention can be set forth in the following description of a mode for carrying out the invention (hereinafter, referred to as "embodiment") by reading the following description with reference to the drawings.
