Abstract: A voice recognition system is provided. The voice recognition system according to an embodiment of the present disclosure includes a voice recognition agent configured to receive voice data from a user and transmit the voice data to an artificial intelligence server, and the artificial intelligence server configured to input the voice data to a voice recognition model, transmit a recognition result based on the voice data to the voice recognition agent, and learn the voice data. When a voice recognition rate for the voice data is lower than a preset reference, the voice recognition agent is configured to request the user for additional data for learning voice data of a user.

Abstract: An artificial intelligence server is disclosed. The artificial intelligence server includes an input unit to which input data is inputted, and a processor, when a first output value outputted by an artificial intelligence model with respect to first input data is correct and a second output value outputted by the artificial intelligence model with respect to second input data is incorrect, configured to use the first input data and the second input data to obtain a first domain causing an incorrect answer, and train the artificial intelligence model to be domain-adapted for the first domain.
