Recent work has demonstrated the perceptual importance of the long-time phase of speech. In this paper, the possibility of using the long-time phase of the LPC residual signal in speech synthesis is investigated. The perceptual importance of the various parts of the long-time spectrum of the residual is also suggested.

We perform a blind multi-component analysis of the WMAP 1 year foreground cleaned maps using SMICA (Spectral Matching Independent Component Analysis). We provide a new estimate of the CMB power spectrum as well as the amplitude of the CMB anisotropies across frequency channels. We show that the CMB anisotropies are compatible with temperature fluctuations as expected from the standard paradigm....

The power spectral density (PSD) of heart rate variability (HRV) contains a power-law relationship that can be obtained by plotting the logarithm of PSD against the logarithm of frequency. The PSD of HRV can be decomposed mathematically into a power-law function and a residual HRV (rHRV) spectrum. Almost all rHRV measures are significantly smaller than their corresponding HRV measures except th...

This paper presents a new pitch-based spectral enhancement algorithm on voiced frames for speech analysis and noiserobust speech processing. The proposed algorithm determines a time-warping function (TWF) and the speaker’s pitch with high precision, simultaneously. This technique reduces the smearing effect in between harmonics when the fundamental frequency is not constant within the analysis ...

We consider a recently proposed scenario for the generation of primordial cosmological perturbations, the so called Cosmological Slingshot scenario. We firstly obtain a general expression for the Slingshot primordial power spectrum which extends previous results by including a blue prebounce residual contribution at large scales. Starting from this expression we numerically compute the CMB temp...
