Abstract: Provided are an electronic apparatus and method for performing an operation based on recognizing a user's command utterance without a call word.

Abstract: Disclosed is a method of controlling an electronic apparatus. The method of controlling an electronic apparatus includes: displaying a screen including an input area configured to receive a text, receiving a speech and obtaining a text corresponding to the speech, performing a service operation corresponding to the input area by inputting the obtained text to the input area, and based on a result of performing the service operation, obtaining a plurality of similar texts including a similar pronunciation with the obtained text, and repeatedly performing the service operation by sequentially inputting the plurality of obtained similar texts to the input area.

Abstract: Provided are a device for recognizing a speech input including a named entity from a user and an operating method thereof. The device is configured to: generate a weighted finite state transducer model by using a vocabulary list including a plurality of named entities; obtain a first string from a speech input received from a user, by using a first decoding model; obtain a second string by using a second decoding model that uses the weighted finite state transducer model, the second string including a word sequence, which corresponds to at least one named entity, and an unrecognized word sequence not identified as a named entity; and output a text corresponding to the speech input by substituting the unrecognized word sequence of the second string with a word sequence included in the first string.
