According to Tianyancha intellectual property information, on July 25, the patent for "out-of-vehicle voice control method, device, storage medium and electronic device" applied by Xiaomi Automobile Technology Co., Ltd., Beijing Xiaomi Mobile Software Co., Ltd., and Beijing Xiaomi Pinecone Electronics Co., Ltd. was announced. The abstract shows that the present disclosure relates to the field of artificial intelligence technology, wherein the method includes: first obtaining the audio signal collected by the microphone array on the vehicle for different areas outside the vehicle; then preprocessing the audio signal; performing sound source location and sound source separation according to the preprocessed audio signal to obtain a multi-channel audio signal; then performing wake-up word recognition based on the multi-channel audio signal to determine the target channel where the wake-up word is located; and executing the corresponding vehicle voice control command according to the audio signal corresponding to the target channel. The present disclosure collects audio signals through microphone arrays in different areas around the vehicle, and obtains multi-channel audio signals after preprocessing, sound source location and separation, thereby realizing accurate wake-up word recognition and voice control command execution, which can effectively shield the complex outdoor environmental noise and greatly improve the accuracy of out-of-vehicle voice control.
