Sensitivity Analysis of a Dual-Microphone Speech Enhancement Algorithm Regarding Different Noise Levels

Speech enhancement is the fundamental base of the speech recognition systems. Different algorithms are available for speech enhancement particularly methods that are based on dual-microphone. In this paper coherence function is used as an algorithm for speech enhancement for a dual-microphone input system. In this paper the sensitivity of a dual-microphone speech enhancement algorithm based on coherence function is analyzed to determine how much this method is robust with the presence of different noise levels. It is important to determine the robustness of the coherence function algorithm in different noise conditions.
