From: Bayesian STSA estimation using masking properties and generalized Gamma prior for speech enhancement
Spectrograms of (a) input noisy speech, (b) clean speech, (c) enhanced speech by WE estimator with Chi prior in [34], (d) enhanced speech by WCOSH estimator with Chi prior in [34], (e) enhanced speech by Log-MMSE estimator with GGD prior in [33], and (f) enhanced speech by the proposed W β-SA estimator with GGD prior in Section 4, in case of babble noise (Input SNR = 5 dB)
