An algorithm for objective speech quality assessment based on Gammatone filter
Chao Liang · Journal of Changchun University of Technology · 2010
A new approach to simulate the human basilar membrane based on Gammatone filter is put forward,so the triangle filter bank is replaced to improve the similarity of subjective evaluation and decrease the frequency shift sensitivity of the resonant peak.The capabilities of objective measurement to extract the resonant peak parameters from the noisy environments are enhanced.The experimental results show that the algorithm can effectively improve the similarity with the MOS.
