Abstract:
A speech enhancement method is provided. The speech enhancement method includes: estimating a direction of a speaker by using an input signal, generating direction information indicating the estimated direction, detecting speech of a speaker based on a result of the estimating the direction, and enhancing the speech of the speaker by using the direction information based on a result of the detecting the speech.

Claim (Index 1):
An electronic device comprising:\n a plurality of microphones; a processor configured to:\n detect, from at least one of the plurality of microphones, a signal associated with a speech of a speaker for initiating direction estimation of the speaker; \n based on the signal associated with the speech of the speaker being detected:\n estimate a direction of the speaker, based on a plurality of signals received from at least two of the plurality of microphones; and \n beamform the received plurality of signals such that at least one of the plurality of signals from the estimated direction is emphasized and at least another one of the plurality of signals is suppressed; and \n \n output the plurality of beamformed signals to perform speech recognition based on the plurality of beamformed signals.
