Unveiling optimal mother wavelets by COPRAS Method Analyzing speech signals despite face mask and shield obstacles

Abstract Wavelet analysis is a prominent time–frequency analysis method in investigating various signals such as speech, vibration, acoustic signals, ultrasound, and underwater acoustic signals. Throughout the coronavirus pandemic, people have adopted diverse face shields and face masks, which have...
