PURPOSE: A location tracing apparatus using user voice and method thereof are provided to reduce voice recognition degradation by echo sound and to integrate a sound source location determination technology. CONSTITUTION: A sound source determining unit(10) divides two channel signals by sound source. A stereo wiener filter unit(20) removes a noise from a sound source signal that is separated by the sound source determining unit. The stereo wiener filter unit filters a residual signal factor. A voice recognition unit(60) recognizes the voice of a user from the separated sound source signal and measures the reliability for a voice recognition result. A channel select unit(80) selects a target channel based on the reliability for the voice recognition result. A sound source location tracing unit(130) analyzes an interfere channel signal and a target channel signal. |
