Abstract: An electronic apparatus including: a communication interface; a memory to store meta data corresponding, respectively, to a plurality of contents including a first content and a second content; and at least one processor configured to acquire characteristic information corresponding to the first content and the second content, respectively, based on first content information of the first content and second content information of the second content received through the communication interface, provided the first content information of the first content and the second content information of the second content, do not match each other, and provide a chatting room for the first content and the second content provided the first content and the second content are a same content based on the received first content information and the second content information, the acquired characteristic information, and the meta data stored in the memory.

Abstract: An electronic device including a speaker; a microphone; a memory configured to store a voice recognition model; and a processor configured to: identify, while a first sound signal is input through the microphone, whether a wake-up word is included in a second sound signal that is output through the speaker by inputting the second sound signal into a wake-up word detection model, and identify, based on identifying that the wake-up word is not included in the second sound signal, whether the wake-up word is included in the first sound signal by inputting the first sound signal into the wake-up word detection model.

Abstract: An electronic apparatus includes a processor configured to: identify a noise characteristic based on a first audio signal received through a microphone, identify whether a second audio signal received through the microphone has a predetermined similarity level to a trigger command based on reference data, the reference data being selected from among pieces of reference data having a plurality of noise characteristics, respectively, and the selected reference data having a noise characteristic corresponding to the identified noise characteristic, and perform an operation corresponding to a user speech input based on a third audio signal received after the second audio signal having the predetermined similarity level.

Abstract: An electronic apparatus and a controlling method thereof are provided. The electronic apparatus includes a communication interface and a processor configured to: receive one or more speech recognition requests from at least one of a plurality of external apparatuses, each of the one or more speech recognition requests including a start command recognized by the at least one of the plurality of external apparatuses; identify whether a number of the one or more speech recognition requests within a time section exceeds a predetermined threshold; control speech recognition to be performed based on the number of the one or more speech recognition requests not exceeding the predetermined threshold; and transmit a result of the speech recognition to the at least one of the plurality of external apparatuses.
