Glottal Source Estimation using an Automatic Chirp Decomposition
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).
Excitation-based Voice Quality Analysis and Modification
This paper investigates the differences occuring in the excitation for different voice qualities.
Causal-Anticausal Decomposition of Speech using Complex Cepstrum for Glottal Source Estimation
Via a systematic study of the windowing effects on the deconvolution quality, we show that the complex cepstrum causal-anticausal decomposition can be effectively used for glottal flow estimation when specific windowing criteria are met.
Complex Cepstrum-based Decomposition of Speech for Glottal Source Estimation
Homomorphic analysis is a well-known method for the separation of non-linearly combined signals.
A Comparative Study of Glottal Source Estimation Techniques
Techniques based on the mixed-phase decomposition and on a closed-phase inverse filtering process turn out to give the best results on both clean synthetic and real speech signals.
