Time delay estimation (TDE) is an important part of sound source localization in hands-free communication systems. TDE in room acoustic environments is usually affected by reverberation. To improve the robustness of time delay estimators to reverberation, a novel TDE algorithm is proposed from information theory perspective. The non-mutual information among multiple microphone signals is extracted to estimate the time delay. Superiority of the proposed algorithm is demonstrated in reverberant environments. © 2013 Elsevier Ltd. All rights reserved.
