Abstract

The invention provides a vehicle-mounted multi-sound-zone sound source detection method, device and system. The method comprises the following steps: acquiring audio information recorded by each radiodevice to obtain multiple paths of audio information, calculating and comparing wake-up scores of the multiple paths of audio information, acquiring audio information corresponding to the maximum wake-up score, determining a sound area where the audio information corresponding to the maximum wake-up score is located, and determining a sound source position based on the sound area. According to the method, people at different positions in the vehicle can be distinguished, so that the purpose of better interactive experience is achieved, and the problem that an instruction issued by a driver orinstructions issued by members at other positions cannot be distinguished in the vehicle is solved.

Description

technical field [0001] The invention belongs to the technical field of speech recognition, and in particular relates to a vehicle-mounted multi-sound zone sound source detection method, device and system. Background technique [0002] With the advancement of science and technology, the continuous development of artificial intelligence is not limited to the interaction between people. As the voice interaction technology becomes more and more mature, it is more of the interaction between people and smart devices. At present, the voice interaction Technology has been applied to more fields. For example: Voice interaction technology is used in the automotive field. Specifically, the use of voice interaction technology in the automotive field is to place two microphones on the console of the car, and perform noise reduction processing for the driver's direction to increase the success rate of the driver's voice interaction. improve. [0003] Although members elsewhere in the ca...
