The disclosure relates to an electronic apparatus configured to, identifying that whether a correction of echo elimination on a sound signal which is received through a sound receiver is needed, output a test sound signal to an external speaker, identify a correction value of the echo elimination based on a characteristic difference between the test sound signal and a feedback sound signal received from the external speaker in response to the output test sound signal, and obtain a user voice signal by performing the echo elimination on a sound signal received through the sound receiver based on the correction value.
