Abstract: | This paper considers a single channel speech enhancement algorithm, which is based on our previous work on β-order minimum mean square error (MMSE) spectral estimation. We propose to make β a function of both local and frame signal-to-noise ratios (SNRs) in order to achieve more effective preservation of weak speech components. Moreover, by taking into account the speech-presence uncertainty in the adaptive β-order MMSE algorithm, we achieve a significant noise reduction and an improved spectral estimation of weak speech components. Experiments also show that the proposed estimator outperforms other well known speech enhancement algorithms. |
