Provided is an artificial intelligence apparatus for predicting a performance of a voice recognition model in a user environment including: a memory configured to store a performance prediction model; and a processor configured to: obtain first controlled environment data including first controlled environment factors corresponding to a first controlled voice recognition environment and a first controlled voice recognition performance of a target voice recognition model in the first controlled voice recognition environment; obtain first user environment factors corresponding to a first user environment, in which the performance is to be predicted; predict, using the performance prediction model, a first user voice recognition performance of the target voice recognition model in the first user voice recognition environment from the obtained first controlled environment data and the first user environment factors; and output the predicted first user voice recognition performance.
