A Noise Estimation Method Based on Speech Presence Probability and Spectral Sparseness

Abstract

This paper addresses the problem of noise power spectrum estimation. Existing noise estimation methods cannot perform quite reliably when noise level increasing abruptly (e.g., narrowband noise bursts). To overcome this problem, we improve the time-recursive averaging algorithm based on speech presence probability (SPP), by exploiting the sparseness of… (More)
