Speaker-dependent speech features are usually estimated using the Short Time Fourier Transform (STFT) method. However, due to the non-stationary nature of speech signals, a fixed-sized window function used by STFT is insufficient to provide accurate time-frequency resolution. In this study, a Discre...
