Abstract

The invention discloses a sound source tracking method and device, and relates to the technical field of computers. A specific implementation of the method includes: identifying a new sound source from the localized potential sound sources, and the new sound source is a sound source different from the tracking sound source in the current filter channel; if the current filter channels are all occupied, then each of the tracking sound sources is evaluated, and a tracking sound source is selected according to the evaluation result; the selected tracking sound source is deleted from the filter channel where it is located, so that the new sound source is used as the tracking sound source added to this filter channel. This embodiment enables timely tracking of new sound sources when they appear, and sets the appropriate number of filter channels according to hardware resources and computing capabilities, solving the problem of insufficient computing resources for filter channels.

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...
