The invention provides an in-vehicle and out-vehicle directional voice interaction system and a vehicle thereof. The vehicle is characterized in that the top or at least one side of the vehicle is provided with a directional sound receiving and sending device; the directional sound receiving and emitting device comprises a directional microphone array and a directional sound emitting loudspeaker, and the directional microphone array is used for directionally receiving sound information; the directional sound production loudspeaker is used for directionally sending sound information; and the controller is used for controlling the directional microphone array and the directional sounding loudspeaker. Under the condition that windows of the vehicle are not opened, sound of vehicles or pedestrians outside the vehicle is directionally collected through the directional microphone array outside the vehicle, the sound is transmitted into the vehicle to be played, it is guaranteed that the sound outside the vehicle smoothly reaches the interior of the vehicle, meanwhile, the sound inside the vehicle is recorded through the microphone inside the vehicle, and the sound is recorded through the microphone inside the vehicle. In-vehicle sound is played through the out-vehicle directional sound production loudspeaker or the AVAS system loudspeaker, on one hand, normal sound communication between vehicles and between the vehicles and pedestrians is ensured; and on the other hand, environmental noise outside the vehicle is isolated and shielded.
本申请提供一种车内外定向语音交互系统及其车辆,该车辆包括:车辆的顶部或至少一侧安装有定向收发声装置;定向收发声装置包括定向麦克风阵列与定向发声扬声器,定向麦克风阵列,用于定向接收声音信息;定向发声扬声器,用于定向发送声音信息;控制器,用于控制定向麦克风阵列与定向发声扬声器。本申请在车辆不开窗的情况下,通过车外定向麦克风阵列,定向采集车外的车辆或行人的声音,将声音传输到车内进行播放,保证车外部声音顺利达到车辆内部,同时,利用车内麦克风收录车内声音,再通过车外定向发声扬声器或AVAS系统扬声器播放车内声音,一方面,确保了车辆之间、车辆与行人之间正常声音交流;另一方面,对车外环境噪音进行隔离屏蔽。
