“…Moreover, the same rates are 36.3% and 39.1% higher for the four "hard" classes in Experiments 1 and 2 in Table 3, respectively, as compared with the use of the MFCCs only. It is important to mention that similar conclusions are drawn from the classification results obtained from speech rather than audio signals [17]. It is also important that the higher classification rates obtained when phase spectral features are combined with magnitude spectral features have been observed uniformly across all the experiments carried out here.…”

“…It plays a wide role to recognize the pattern [13][14][15]. 'Hartley Phase Spectrum (HPS)' summarizes the phase content of the function more accurately, compared with its Fourier counter audio (gunshot) classification [16], speech (phoneme) classification [17] Revised…”

“…Thus, the ‘Whitened Hartley spectrum’ or ‘Hartley Phase Spectrum (HPS)’ encapsulates the phase content of the signal more efficiently, compared with its Fourier counterpart. Moreover, the HPS has already found useful application in: audio (gunshot) classification [19, 22], speech (phoneme) classification [23–25] and as a noise robust feature for signal analysis [26]. Please note that the terms ‘Whitened Hartley spectrum’ and ‘HPS’ are used in this paper interchangeably since both of them convey the same meaning.…”
