N2 - A single channel speech enhancement algorithm is proposed based on reassigned spectrogram and masking properties of the human auditory system. According to the strong correlation of speech harmonics, the correlation of adjacent frames and that of harmonics of the reassigned spectrogram are adopted to control the forgetting factor of the two-step-decision-directed method, and it can suppress the non-speech components better. Then, the estimated speech spectra is used to compute the noise masking threshold of a perceptual gain factor according to the masking properties of the human ear. Experimental results show that the proposed algorithm can improve the intelligibility of speech signals while removing the background noise.
