Source location attracts more attentions in speech communication systems. Multiple signal classification (MUSIC) and time difference of arrival (TDOA) based location methods are two kinds of source localization techniques. However, MUSIC requires a search of whole region of interest (ROI), which is supposed to be computationally expensive. For another, the location accuracy of second group is restricted...
Array based source location attracts a growing interest nowadays, which is frequently used in videoconference, hearing aids and hands free telephone systems to detect a speaker's position. Time delay estimation (TDE) based dual-step source location is assumed to be classical method in this field. Recently, a new technique is developed based on interaural level difference (ILD) method, which determines...
