Causal-Anticausal Decomposition of Speech using Complex Cepstrum for Glottal Source Estimation
Thomas Drugman, Baris Bozkurt, Thierry Dutoit
Complex cepstrum is known in the literature for linearly separating causal and anticausal components. Relying on advances achieved by the Zeros of the Z-Transform (ZZT) technique,…
Complex Cepstrum-based Decomposition of Speech for Glottal Source Estimation
Thomas Drugman, Baris Bozkurt, Thierry Dutoit
Homomorphic analysis is a well-known method for the separation of non-linearly combined signals. More particularly, the use of complex cepstrum for source-tract deconvolution has b…
A Comparative Study of Glottal Source Estimation Techniques
Thomas Drugman, Baris Bozkurt, Thierry Dutoit
Source-tract decomposition (or glottal flow estimation) is one of the basic problems of speech processing. For this, several techniques have been proposed in the literature. Howeve…
