Electronic device and method of controlling the same

An electronic device comprising:

• a memory configured to store executable instructions;
• and
• a processor configured to execute the executable instructions to:
• determine a text corresponding to a received command,
• provide response information on the command based on the text being classified as a text corresponding to one of a plurality of pre-stored texts by a first artificial intelligence model, and
• provide error information based on the text being classified as an error by the first artificial intelligence model,
• wherein the first artificial intelligence model is configured to classify the text as the error based on the text corresponding to the command being a similar text having at least one of an entity and an intent different from at least one of the plurality of pre-stored texts;
• wherein the similar text is to be generated by the processor via a second artificial intelligence model,
• wherein the processor via the first artificial intelligence model is configured to determine whether the similar text input to the first artificial intelligence model corresponds to one of the plurality of pre-stored texts, and to determine whether to perform learning based on the determination result, and
• wherein the processor via the second artificial intelligence model is configured to perform the learning to generate a new similar text having a higher similarity than the similar text to at least one text, based on the first artificial intelligence model determining that the similar text does not correspond to the plurality of pre-stored texts.
