Apparatus for recognizing user's voice using microphone array and method of driving the microphone array

摘要

A voice recognition apparatus for recognizing a voice by using a microphone array and a microphone array driving method thereof are provided to mount the microphone array in an endfire type, and protrude the microphone array if a user is recognized, thereby suppressing surrounding noise through the microphone array and receiving a voice signal more accurately. A voice recognition apparatus includes a microphone array(504), a microphone array mounting unit(502), a microphone array driver(506), a beam forming unit(508), a control unit(500), and a memory unit(510). The microphone array is composed of at least one microphone, and is mounted in an endfire type to the voice recognition apparatus to receive a voice in an endfire direction. The microphone array mounting unit mounts the microphone array. The microphone array mounting unit protrudes or mounts the microphone array according to a control signal for driving the microphone array. The control unit outputs the control signal for protruding the microphone array to the microphone array mounting unit if a user is recognized.
