Measures of the glottal source spectrum.
PURPOSE Many researchers have studied the acoustics, physiology, and perceptual characteristics of the voice source, but despite significant attention, it remains unclear which aspects of the source should be quantified and how measurements should be made. In this study, the authors examined the relationships among a number of existing measures of the glottal source spectrum, along with the ass...
متن کاملUnified analysis of glottal source spectrum
The spectral study of the glottal excitation has traditionally been based on a single time-domain mathematical model of the signal, and the spectral dependence on its time domain parameters. Opposite to this approach, in this work the two most widely used time domain models have been studied jointly, namely the KLGLOTT88 and the LF models. Their spectra are analyzed in terms of their dependence...
متن کاملGlottal spectrum based inverse filtering
In this paper a new inverse filtering technique for the timedomain estimation of the glottal excitation is presented. This approach uses the DAP modeling for the vocal tract characterization, and a spectral model for the derivative of the glottal flow. This spectral model is based on the spectrum of the KLGLOTT88 model for the glottal source. The proposed procedure removes the glottal source fr...
متن کاملTowards robust glottal source modeling
We present here a new method for the simultaneous estimation of the derivative glottal waveform and the vocal tract filter. The algorithm is pitch-synchronous and uses overlapping frames of several glottal cycles to increase the robustness and quality of the estimation. Two parametric models for the glottal waveform are used: the KLGLOTT88 during the convex optimization iteration, and the LF mo...
متن کاملOn the interdependencies between voice quality, glottal gaps, and voice-source related acoustic measures
In human speech production, the voice source contains important non-lexical information, especially relating to a speaker’s voice quality. In this study, direct measurements of the glottal area waveforms were used to examine the effects of voice quality and glottal gaps on voice source model parameters and various acoustic measures. Results showed that the open quotient parameter, cepstral peak...
