Abstract
A method for eliminating a specific object voice and an ear-wearing audio device using the same are provided. The ear-wearing audio device includes a plurality of voice receiving units, a voice direction tracking unit, a direction enhancement unit, a window cutting unit, a voiceprint recognition unit, a voice cancellation unit and two speakers. The voice receiving units are arranged in an array to obtain a sound signal. The voice direction tracking unit is configured to track a plurality of sound sources to obtain a plurality of sound source directions. The voiceprint recognition unit determines whether the sound signal contains a specific object voice in each of the sound source directions. If the sound signal contains the specific object voice in one of the sound source directions, the voice cancellation adjusts a field pattern using a beamforming technique to eliminate the specific object voice.
