    • 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.
    • 提供了一种用于通过使用麦克风阵列和麦克风阵列驱动方法来识别语音的语音识别装置,以将麦克风阵列安装在端射型中,并且如果用户被识别则突出麦克风阵列,从而通过麦克风抑制周围的噪声 阵列并更准确地接收语音信号。 语音识别装置包括麦克风阵列(504),麦克风阵列安装单元(502),麦克风阵列驱动器(506),波束形成单元(508),控制单元(500)和存储单元 )。 麦克风阵列由至少一个麦克风组成,并且以端火类型安装到语音识别装置以在端射方向上接收声音。 麦克风阵列安装单元安装麦克风阵列。 麦克风阵列安装单元根据用于驱动麦克风阵列的控制信号突出或安装麦克风阵列。 如果用户被识别,则控制单元输出用于将麦克风阵列突出到麦克风阵列安装单元的控制信号。
