“…In this database, the five noise types, namely, “airport noise, exhibition noise, restaurant noise, station noise and street noise” are added to the speech signals. The performance of the proposed model (AR-GWO) is compared with the extant modelslike GA [ 29 ], PSO [ 20 ], ABC [ 24 ], FF [ 12 ] and GWO [ 14 ] in terms of “SDR, PESQ, SNR, RMSE, Correlation, ESTOI and CSED”. Also, statistical analysis and computational time analysis are performed.…”

“…This may involve techniques such as breath control [16], pitch and tone modifications [17,18], and articulation exercises [19], including spectral subtraction [20], Wiener filtering [21], and statistical prediction model-based [22] or machine learning-based approaches [23]. However, these traditional methods often suffer from drawbacks such as introducing artifacts, suppressing the desired speech components, or being computationally expensive.…”
