Web1 Oct 2005 · As a linear transformation, subband analysis has been proven to be an appropriate and effective pre-processing for PCA- and ICA-based blind source separation (BSS) methods [6]. In this paper, we use two types … Web4 Apr 2024 · Subband modeling for spoofing detection in automatic speaker verification. Spectrograms - time-frequency representations of audio signals - have found widespread use in neural network-based spoofing detection. While deep models are trained on the fullband spectrum of the signal, we argue that not all frequency bands are useful for these …
