Improved Estimation of Evolutionary Spectrum based on Short Time Fourier Transforms and Modified Magnitude Group Delay by Signal Decomposition
A new estimator for evolutionary spectrum (ES) based on short time Fourier transform (STFT) and modified group delay function (MGDF) by signal decomposition (SD) is proposed. The STFT due to its built-in averaging, suppresses the cross terms and the MGDF preserves the frequency resolution of the rectangular window with the reduction in the Gibbs ripple. The present work overcomes the magnitude ...
متن کاملTime Delay Estimation for Speech Signal Based on FOC-Spectrum
Higher-order statistics can be used for time delay estimation (TDE) to suppress spatially correlated Gaussian noise, since the higher-order cumulant of Gaussian signal is always zero. However, third-order statistics is invalid for those signals with zero skewness, speech signal as a typical one. In this paper, the fourth-order cumulant (FOC) spectrum is derived, based on which a TDE algorithm t...
متن کاملEstimation of glottal closure instants from telephone speech using a group delay-based approach that considers speech signal as a spectrum
Glottal closure instants (GCIs) are characterized by a strong negative valley in the speech signal and an abrupt change in the amplitude. In this paper, an algorithm that exploits these two properties of a GCI is proposed to estimate the location of GCIs, specifically from telephone speech. The algorithm considers a symmetrized voiced segment as the Fourier transform of an even signal. In such ...
متن کاملEstimation of evolutionary spectrum based on short time Fourier transform and modified group delay
This paper proposes a new estimator for evolutionary spectrum (ES) based on short time Fourier transform (STFT) and modified group delay function (GDFM). The STFT due to its built-in averaging suppresses the crossterms and the GDFM preserves the frequency resolution of the rectangular window as it reduces the Gibbs ripple without using any window function. The new estimator is applicable to ran...
متن کاملModified Group Delay Based MultiPitch Estimation in Co-Channel Speech
Phase processing has been replaced by group delay processing for the extraction of source and system parameters from speech. Group delay functions are ill-behaved when the transfer function has zeros that are close to unit circle in the z-domain. The modified group delay function addresses this problem and has been successfully used for formant and monopitch estimation. In this paper, modified ...
