傳統聲源定位的方法大多利用當下時刻麥克風陣列所收到的資訊來計算聲源位置；但由於聲源位置估計可能因迴響而造成定位劇烈誤差，故本論文以聲源到達兩相鄰麥克風之間的相對時間延遲(TDOA，Time duration of arrival)為基礎，利用粒子濾波器(Particle Filter)對聲源做追蹤以避免定位誤差的產生。但由於聲源追蹤仍存在著無法追蹤非單一非連續聲源的狀況，故本論文提出了一個架構，針對粒子濾波器無法追蹤非單一連續出聲聲源的狀況做改善，藉此完成一個相對可靠的多聲源的聲源追蹤定位系統。
本論文所提出的架構共分成兩個主要的部份，第一個部分提出了聲源追蹤的重置機制，利用這個重製的機制我們可以避免掉追蹤物不存在的狀況；第二個部分為聲源數的即時確認機制，本論文以不同的位置有不同的聲源及不同的聲源具有不同的內容為假設，利用聲源萃取來分離聲源，並以分離出來的聲源提出一個聲源數目確認的機制，利用這個機制我們可以即時的確認聲源數目，解決因聲源數目未知所產生的定位誤差，最後經由實驗證實本論文所提出的兩項機制確實能夠解決傳統聲源追蹤輔助定位會發生的困難，並減少因空間迴響所造成的定位誤差。
