Voice recognition device and voice recognition system
A voice recognition device includes a recognition processor configured to perform a voice recognition process that recognizes an input voice, a memory that stores information indicating a condition of a vehicle in association with information indicating a target state of an in-vehicle device targeted when changing from the condition and information of voice notification for confirming the change, and a control unit. The control unit is configured to control the in-vehicle device to enter the target state corresponding to the condition when the vehicle is in the vehicle condition stored in the memory and an input voice is recognized as a response to the voice notification corresponding to the condition, and to stop the voice recognition process performed by the recognition processor when recognizing that the state of the in-vehicle device is the target state.
1. A voice recognition device comprising:
a recognition processor configured to perform a voice recognition process that recognizes an input voice;
a memory that stores information indicating a condition of a vehicle in association with information indicating a target state that is a state of an in-vehicle device targeted when changing from the condition and information of voice notification for confirming the change; and
a control unit configured so that when the vehicle is in the vehicle condition stored in the memory and an input voice is recognized as a response to the voice notification corresponding to the condition, the control unit controls the in-vehicle device to enter the target state corresponding to the condition,
wherein the control unit is configured to stop the voice recognition process performed by the recognition processor when recognizing that the state of the in-vehicle device is the target state corresponding to the vehicle condition stored in the memory.
2. The voice recognition device according to claim 1 , wherein
the target state is a state after operation of an in-vehicle device that needs to be operated, and
the control unit is configured to perform control, as the control for changing a state of the in-vehicle device to the target state, for automatically changing the state of the in-vehicle device to the state after the operation.
3. The voice recognition device according to claim 1 , wherein when target states that respectively correspond to a plurality of in-vehicle devices are stored in the memory in association with a single vehicle condition, the control unit is configured to stop the voice recognition process performed by the recognition processor when recognizing that the in-vehicle devices have all reached the corresponding target states.
4. The voice recognition device according to claim 1 , wherein
the control unit is connected via a vehicle network to one or more in-vehicle controllers, each configured to control a state of a corresponding in-vehicle device,
the one or more in-vehicle controllers are each configured to output the state of the corresponding in-vehicle device to the control unit via the vehicle network when the state of the corresponding in-vehicle device changes to the target state, and
the control unit is configured to stop the voice recognition process performed by the recognition processor when an input state of an in-vehicle device matches the target state of the corresponding in-vehicle device stored in the memory.
5. A voice recognition system comprising:
an information terminal having a voice input function; and
an external server that performs a voice recognition process that recognizes a voice transmitted from the information terminal and returns information indicating a recognition result of the voice to the information terminal, wherein
the information terminal includes:
a memory that stores information indicating a condition of a vehicle in association with information indicating a target state that is a state of an in-vehicle device targeted when changing from the condition and information of voice notification for confirming the change; and
a control unit configured so that when the vehicle is in the vehicle condition stored in the memory and information indicating a result of an input voice being recognized as a response to the voice notification corresponding to the condition is received from the external server, the control unit controls the in-vehicle device to enter the target state corresponding to the condition,
wherein the control unit is configured to transmit an instruction to the external server to stop the voice recognition process when recognizing that the state of the in-vehicle device is the target state corresponding to the vehicle condition stored in the memory.
