Leveraging the multiscale analysis properties of wavelet transform, this approach improves basic frequency-domain spectral subtraction by applying different thresholds at various wavelet domain scales. It separates voiced and unvoiced sounds during denoising based on their distinct characteristics, preserving unvoiced components to produce fuller-sounding speech while employing adaptive algorithms to further enhance signal quality.
