1. A dialogue system comprising:
a voice recognition module provided to execute voice recognition;
a storage device in which a result of the executed voice recognition is stored; and
a controller communicatively connected to the voice recognition module and the storage device and configured to
determine priorities of an external event and the voice recognition when the external event occurs while an utterance of a user is input, and
pause the execution of the voice recognition and store a result of the voice recognition of the utterance of the user inputted before the pause in the storage device, when the controller concludes that the priority of the external event is higher than the priority of the voice recognition,
wherein the controller is configured to determine whether the input of the utterance of the user is interrupted during detection due to the external event by analyzing information stored in the storage device,
wherein, when the controller concludes that the input of the utterance of the user is interrupted during the detection as a result of the determining whether the input of the utterance of the user is interrupted, the controller is configured to re-analyze whether the input of the utterance of the user is interrupted and the utterance of the user determined that the input has been interrupted, and to store a re-analysis result in the storage device,
wherein the controller is configured to generate a natural language for requesting an additional utterance following the interrupted utterance of the user, and output a voice corresponding to the generated natural language, and
wherein the controller is configured to determine whether the input of the utterance of the user is interrupted based on detection of at least one signal among an outgoing call signal triggered by a user's input requesting a call, an incoming call signal, and an activation signal of a rear camera, and
wherein the voice recognition module, the storage device, and the controller are mounted in a voice recognition system in a vehicle.
