Speech enhancement is necessary for increasing the quality of speech. However, the presence of noise signals can corrupt speech signals. Thereby, this work intends to propose a new speech enhancement framework that includes (a) training phase and (b) testing phase. The input signal is first given to STFT-based noise estimate and NMF-based spectra estimate during the training phase in order to compute the noise spectra and signal spectra, respectively. The obtained signal spectra and noise spectra are then Wiener-filtered, then empirical mean decomposition (EMD) is used. Because the tuning factor of Wiener filters is so important, it should be computed for each signal by coaching in a fuzzy wavelet neural network (FW-NN). Subsequently, a bark frequency is computed from the denoised signal, which is then subjected to FW-NN to identify the suitable tuning factor for all input signals in the Wiener filter. For optimal tuning of [Formula: see text], this work deploys the fitness-oriented elephant herding optimization (FO-EHO) algorithm. Additionally, an adaptive Wiener filter is used to supply EMD with the ideal tuning factor from FW-NN, producing an improved speech signal. At last, the presented approach\u2019s supremacy is proved with varied metrics. <\/jats:p>","DOI":"10.1142\/s0219691322500321","type":"journal-article","created":{"date-parts":[[2022,7,21]],"date-time":"2022-07-21T17:18:23Z","timestamp":1658423903000},"source":"Crossref","is-referenced-by-count":7,"title":["Speech enhancement via adaptive Wiener filtering and optimized deep learning framework"],"prefix":"10.1142","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8064-3107","authenticated-orcid":false,"given":"Amarendra","family":"Jadda","sequence":"first","affiliation":[{"name":"Department of Electronic and Communication Engineering, Jawaharlal Nehru Technological University, Kakinada, Andhra Pradesh 533003, India"}]},{"given":"Inty Santi","family":"Prabha","sequence":"additional","affiliation":[{"name":"Department of Electronic and Communication Engineering, Jawaharlal Nehru Technological University, Kakinada, Andhra Pradesh 533003, India"}]}],"member":"219","published-online":{"date-parts":[[2022,9,21]]},"reference":[{"issue":"1","key":"S0219691322500321BIB001","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1109\/TASLP.2017.2761236","volume":"26","author":"Abel J.","year":"2018","journal-title":"IEEE\/ACM Trans.
