The invention provides a vehicle-mounted multi-tone-area voice interaction method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the frequency domain conversion of a voice signal collected by a target microphone in two pairs of microphones, so as to obtain a frequency spectrum signal; for each frequency point on the frequency spectrum signal, determining a first phase difference of the voice signals collected by the first pair of microphones on each frequency point and a second phase difference of the voice signals collected by the second pair of microphones on each frequency point; determining a sound area to which each frequency point belongs according to the first phase difference and the second phase difference corresponding to each frequency point; determining a voice signal corresponding to each voice area according to the voice area to which each frequency point belongs; and controlling corresponding vehicle-mounted equipment to execute corresponding actions according to the recognition result of the voice signal corresponding to each voice area. According to the method, the voice signals of each voice area can be effectively separated, so that each voice area interacts independently and does not influence each other, and the accuracy of voice interaction on each seat is improved.
本申请提出一种车载多音区语音交互方法、装置、电子设备和存储介质，其中，方法包括：对两对麦克风中的目标麦克风采集的语音信号进行频域转换，以获取频谱信号；针对频谱信号上的每个频点，确定第一对麦克风采集的语音信号在每个频点上的第一相位差及第二对麦克风采集的语音信号在每个频点上的第二相位差；根据每个频点对应的第一相位差和第二相位差，确定每个频点所属的音区；根据各频点所属的音区，确定每个音区对应的语音信号；根据每个音区对应的语音信号的识别结果，控制相应车载设备执行相应动作。该方法可以有效地将各个音区的语音信号分离开，使得各个音区独立交互，互不影响，提高了各座位上语音交互的精准性。
