    Abstract: Provided are an electronic apparatus and method for performing an operation based on recognizing a user's command utterance without a call word. The method includes identifying a dedicated language model related to a displayed content; receiving an utterance of a user; recognizing the received utterance and identifying candidate texts of the recognized utterance; identifying a similarity between the recognized utterance and the identified candidate texts; identifying, based on the identified dedicated language model and a predetermined threshold value, a suitability of a predetermined number of candidate texts with a high identified similarity, among the candidate texts; based on the identified suitability being outside a predetermined suitability range, ignoring the recognized utterance; and based on the identified suitability being in the predetermined suitability range, identifying a candidate text having a highest suitability, among the candidate texts, as the recognized utterance, and performing a corresponding operation.
