Electronic device and control method thereof

A method for controlling an electronic apparatus, the method comprising:

• based on a user voice in a first language being received, acquiring text in the first language corresponding to the user voice;
• acquiring a first feature vector by inputting the text in the first language to a first encoder;
• transmitting the first feature vector to an external device;
• and
• based on a second feature vector being received from the external device, acquiring text in the first language corresponding to the second feature vector by inputting the second feature vector to a first decoder corresponding to the first language,
• wherein the external device comprises a second encoder corresponding to a second language, and
• wherein the second encoder is configured output the second feature vector based on a second text corresponding to the user voice in the second language being input to the second encoder.

An electronic apparatus comprising:

• a microphone;
• a communication interface comprising communication circuitry;
• a memory configured to store a first encoder and a first decoder corresponding to a first language;
• and
• a processor configured to:
• based on a user voice in the first language being received through the microphone, acquire a first text in the first language corresponding to the user voice;
• acquire a first feature vector by inputting the first text in the first language to the first encoder;
• control the communication interface to transmit the first feature vector to an external device;
• based on a second feature vector being received from the external device through the communication interface, acquire text in the first language corresponding to the second feature vector by inputting the second feature vector to the first decoder;
• identify whether the external device comprises a second decoder corresponding to a second language different from the first language by communicating with the external device via the communication interface;
• based on identifying that the external device comprises the second decoder, transmit the first feature vector to the external device;
• and
• based on identifying that the external device does not comprise the second decoder, transmit the first feature vector to a server.
