The invention discloses a vehicle-mounted voice control method, device, equipment and system based on sound source positioning. The method comprises the following steps: acquiring a voice signal of a user through a microphone array; based on the three-dimensional vehicle coordinate system, determining the position coordinate of each microphone, and calculating the azimuth angle of the voice signal relative to each microphone; according to the position coordinate of each microphone and the azimuth angle of the voice signal relative to each microphone, calculating to obtain the sound source position of the voice signal; analyzing and identifying the voice signal to obtain instruction information; and based on the position relationship between the sound source position and the in-vehicle equipment, determining controlled equipment according to the instruction information, and sending a control instruction to the controlled equipment. According to the technical scheme, equipment at different positions in the vehicle can be accurately controlled through sound source positioning, the convenience and intelligence of voice control are greatly improved, and better use experience is brought to a user.

    本发明公开了一种基于声源定位的车载语音控制方法、装置、设备及系统,所述方法包括:通过麦克风阵列采集用户的语音信号;基于所述三维车辆坐标系,确定每一个麦克风的位置坐标,并计算所述语音信号相对于每一个麦克风的方位角;根据每一个麦克风的位置坐标和所述语音信号相对于每一个麦克风的方位角,计算获得所述语音信号的声源位置;对所述语音信号进行解析和识别,获取指令信息;基于所述声源位置和车内设备之间的位置关系,根据所述指令信息确定被控设备,并向所述被控设备发送控制指令。采用本发明的技术方案能够通过声源定位精准控制车内不同位置的设备,大大提高语音控制的便捷性和智能化,给用户带来更好的使用体验。
