Abstract

The invention discloses a sound source tracking method and device and belongs to the technical field of computers. According to one specific embodiment of the invention, the method includes the following steps that: a new sound source is identified from positioned potential sound sources, wherein the new sound source is a sound source different from tracking sound sources in current filter channels; and if all the current filter channels are occupied, each tracking sound source is evaluated, and a tracking sound source is selected according to evaluation results; and the selected tracking sound source is deleted from the filter channels, so that the new sound source is added to the filter channels as a tracking sound source. With the sound source tracking method and device provided by theembodiments of the invention adopted, the new sound source can be timely tracked when the new sound source appears; and the appropriate number of filter channels can be set according to hardware resources and computing power, and the problem of insufficient computational resources of the filter channels is solved.

Description

technical field

[0001] The present invention relates to the field of computer technology, in particular to a sound source tracking method and device. Background technique

[0002] The microphone array sound source location tracking system uses the microphone array to collect voice signals, processes the collected signals, and uses a certain algorithm to locate and track the position of the sound source. The system can be applied to various occasions such as video conferencing, robot speech recognition, smart home and so on. The location tracking process is divided into two major steps: location and tracking. The main function of positioning is that the microphone array calculates n potential sound source positions (specific values ​​can be set according to actual needs) through the positioning algorithm based on the collected data; the main function of tracking is to use Particle filter technology to track the position of the sound source, where each tracked position corre...
