The invention discloses a sound source tracking method and device for a distributed microphone array and a storage medium, and the method comprises the steps: obtaining sound source signals received by each microphone node in the distributed microphone array, and determining a target microphone node according to the sound source signals received by each microphone node; constructing a local node set according to the target microphone node and the neighborhood microphone nodes thereof; establishing a sound source kinematic model of the sound source signal; according to the sound source kinematics model, local nodes in the local node set are adopted for sound source tracking, and local estimation of the corresponding local nodes on the sound source position is obtained; and fusing the local estimation of each local node on the sound source position to obtain the global estimation of the sound source position, thereby improving the accuracy of sound source tracking and reducing the burden of the whole microphone
