The state-covariance of a linear filter is characterized by a certain algebraic commutativity property with the state matrix of the filter, and also imposes a generalized interpolation constraint on the power spectrum of the input process. This algebraic property and the relationship between state-covariance and the power spectrum of the input allow the use of matrix pencils and analytic interp...

This paper presents a method based on the particle swarm optimization algorithm applied to estimate harmonic components in radial distribution feeders. It is important to mention that this method is not applied as harmonic state estimator, neither to estimate the total harmonic distortion at the substation. So, the proposed method can be employed to estimate the harmonic components in specific ...

In this paper, we present a study on robust pitch estimation by integrating spectral and temporal information in speech. Spectrum harmonics are important representations of the speech fundamental frequency. Harmonic-related spectral peaks of speech evolve much more slowly than the spectral peaks of noise. This motivates the proposition of temporally accumulated peak spectrum (TAPS), which is co...

We present a solution to the problem of modeling, parameter estimation, and synthesis of natural textures. The texture field is assumed to be a realization of a regular homogeneous random field, which can have a mixed spectral distribution. On the basis of a 2-D Wold-like decomposition, the field is represented as a sum of a purely indeterministic component, a harmonic component, and a countabl...

In this study, we propose a frequency domain F0 estimation approach based on long term Harmonic Feature Analysis combined with artificial neural network (ANN) classification. Long term spectrum analysis is proposed to gain better harmonic resolution, which reduces the spectrum interference between speech and noise. Next pitch candidates are extracted for each frame from the long term spectrum. ...

This paper proposes an algorithm to estimate the melody pitch line (the most dominant pitch sequence) of a given polyphonic audio based on melody range estimation and pitch candidate extraction using a harmonic structure model similar to that proposed by Goto. This paper defines melody pitch candidate as a list of pitch candidates that produces the best-fit harmonic models to the polyphonic aud...

Harmonic plus Noise Model (HNM) is the two-band speech model which assumes the speech signal to be composed of a harmonic part and a noise part. It is very important to determine the reasonable maximum voiced frequency which delimit harmonic and noise parts for highquality synthetic speech. In this paper, a new analysis method for HNM, especially maximum voiced frequency, is proposed, whereby t...
