Causal-anticausal decomposition of speech using complex cepstrum for glottal source estimation

Drugman, Thomas; Bozkurt, Barış; Dutoit, Thierry (Elsevier, 2011-07)

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, we here investigate the possibility of ...
A comparative study of glottal source estimation techniques

Drugman, Thomas; Bozkurt, Barış; Dutoit, Thierry (Elsevier, 2012-01)

Abstract: 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. However, studies comparing different ...
Complex cepstrum-based decomposition of speech for glottal source estimation

Drugman, Thomas; Bozkurt, Barış; Dutoit, Thierry (International Speech Communication Association, 2009)

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 been discussed in various articles. However ...
Glottal source estimation using an automatic chirp decomposition

Drugman, Thomas; Bozkurt, Barış; Dutoit, Thierry (Springer, 2010)

In a previous work, we showed that the glottal source can be estimated from speech signals by computing the Zeros of the Z-Transform (ZZT). Decomposition was achieved by separating the roots inside (causal contribution) ...
Phase-based methods for voice source analysis

D’Alessandro, Christophe; Bozkurt, Barış; Doval, Boris; Dutoit, Thierry; Henrich, Nathalie; Tuan, Vu Ngoc; Sturmel, Nicolas (Springer, 2007)

Voice source analysis is an important but difficult issue for speech processing. In this talk, three aspects of voice source analysis recently developed at LIMSI (Orsay, France) and FPMs (Mons, Belgium) are discussed. In ...
