Multi-sound-source positioning method and device, electronic equipment and storage medium

Abstract

The invention provides a multi-sound-source positioning method and device, electronic equipment and a storage medium. The method comprises the steps of: analyzing a multi-sound-source signal obtained by a microphone array to obtain correlation peak information between a plurality of microphones and a reference microphone; screening pure peak information and mixed peak information in the correlation peak information according to the difference values between the serial number of the reference microphone and the serial numbers of the plurality of microphones; calculating each angle of arrival according to the pure peak information, identifying a sound source of each angle of arrival according to the mixed peak information, and determining the angle of arrival from the same sound source; and carrying out sound source positioning according to the arrival angle from the same sound source. According to the method, correlation peak information is divided into a pure peak and a mixed peak, then each angle of arrival is estimated according to the pure peak, the angle of arrival of LOS and the angle of arrival of ECHO belonging to the same sound source are determined according to the sound source, suitable for each angle of arrival, of the mixed peak, and finally sound source positioning under the condition of multiple sound sources is realized.

Description

technical field [0001] The present invention relates to the technical field of sound source positioning, in particular to a multi-sound source positioning method, device, electronic equipment and storage medium. Background technique [0002] Smart devices are becoming more and more popular in our daily life. Voice recognition is an important function of smart devices. Smart speakers support a variety of attractive applications, such as voice control of home appliances, man-machine dialogue, entertainment centers, etc. [0003] With the rapid development of smart homes, there is an increasing demand for sound source localization on smart devices. The ability to locate the sound source greatly improves the understanding ability of smart devices, including but not limited to the following situations: (1) The positioning ability enables the smart speaker to process the user's position-sensitive voice commands: when the user lies on the bed and says "Open If the smart speaker ...
