Speech-envelope processing noise must preserve spectral envelope shape while randomizing phase

Evidence

The spectral shape of the standard and the signal were generated using the equation: where F is the amplitude of a bin with center frequency f (in Hertz), f c is the spectral modulation frequency (in cycles/octave), and θ 0 is the starting phase. Next, noise was added to the phase of each bin prior to computing the inverse Fourier transform. The standard was generated using a spectral contrast c equal to 0. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1831
