The perceptual relevance of glottal-pulse parameter variations
نویسندگان
چکیده
The perceptual relevance of changes to glottal-pulse parameters is studied. First, it is demonstrated that a distance measure based on excitation patterns can predict audibility discrimination thresholds for small changes to the R parameters of the Liljencrants-Fant (LF) model. Next, by using this measure the perceptual relevance of the LF parameters is quantified. Results are presented for a number of sets of glottal-pulse parameters that were taken from literature, representing distinct voice qualities.

A method for analysing the perceptual relevance of glottal-pulse parameter variations
This paper describes a method for analysing the perceptual relevance of parameter variations of the Liljencrants– Fant (LF) model for the glottal pulse. A perceptual distance measure based on excitation patterns was developed and evaluated in order to predict audibility discrimination thresholds for small changes to the R-parameters of the LF model. For a number of R-parameter sets, taken from ...
متن کاملThe spectral relevance of glottal-pulse parameters
The paper analyses how variations of the parameters of the Liljencrants-Fant (LF) model of glottal flow influence the speech spectrum, in order to determine the spectral relevance of these parameters. The effects of small parameter variations are described analytically. This analysis also gives an indication to what extent the LF parameters can be estimated reliably from the speech spectrum. Th...
متن کاملInvestigation on the Audibility of Glottal Parameter Variations in Speech Synthesis
Glottal waveform models have long been employed to improve quality in speech synthesis. In this paper the subjective importance of accuracy for some of the Rosenberg glottal source model parameters has been investigated through listener preference judgments. Two paired-comparison tests were conducted involving 14 and 13 listeners, respectively. The parameters, 1) relative opening duration, 2) r...
متن کاملVocal quality factors: analysis, synthesis, and perception.
The purpose of this study was to examine several factors of vocal quality that might be affected by changes in vocal fold vibratory patterns. Four voice types were examined: modal, vocal fry, falsetto, and breathy. Three categories of analysis techniques were developed to extract source-related features from speech and electroglottographic (EGG) signals. Four factors were found to be important ...
متن کاملOn glottal source shape parameter transformation using a novel deterministic and stochastic speech analysis and synthesis system
In this paper we present a flexible deterministic plus stochastic model (DSM) approach for parametric speech analysis and synthesis with high quality. The novelty of the proposed speech processing system lies in its extended means to estimate the unvoiced stochastic component and to robustly handle the transformation of the glottal excitation source. It is therefore well suited as speech system...
