Abstract

The Wiener gain or filter plays an important role in both single-channel and multichannel speech enhancement. Traditional Wiener gain formulations are typically based solely on either the signal-to-noise ratio (SNR) or the coherent-to-diffuse ratio (CDR), rendering them suboptimal in noisy and reverberant environments. In this paper, we present an approach to the design of the Wiener gain by incorporating estimates of both SNR and CDR. Additionally, we introduce two hyperparameters to govern the extent of noise reduction and reverberation suppression. Through simulations, we demonstrate that the proposed approach surpasses widely used methods in terms of SNR gain, log-spectral-distortion (LSD), direct-to-reverberant energy ratio (DRR), and Kurtosis ratio (KR).

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
