A frequency domain method for parametrization of the voice source
نویسندگان
چکیده
A new frequency domain method for the quantification of glottal volume velocity waveforms is presented in this study. This technique, called Parabolic Spectral Parameter (PSP), is based on fitting a parabolic function to a pitchsynchronously-computed spectrum of the estimated voice source. The PSP-algorithm gives a single numerical value that describes how the spectral decay of an obtained glottal flow behaves with respect to theoretical bounds corresponding to maximal and minimal spectral tilting.

Automatic parametrization of voice source signals: a novel evaluation procedure is used to compare methods and test the effect of low-pass filtering
There is a need for automatic methods for parametrization of the voice source signals. Representatives of the two types of methods that have been used most often for parametrization were tested and compared. For this purpose a novel evaluation procedure is proposed which makes it possible to perform the numerous tests needed for a detailed comparison of the methods. This evaluation procedure re...

Introduction: The art of voice mimicking by computers, has with the computer have been one of the most challenging topics of speech processing in recent years. The system of voice conversion has two sides. In one side, the speaker is the source that his or her voice has been changed for mimicking the target speaker’s voice (which is on the other side). Two methods of p...
متن کاملDiscretized Adjoint State Time and Frequency Domain Full Waveform Inversion: A Comparative Study
This study derives the discretized adjoint states full waveform inversion (FWI) in both time and frequency domains based on the Lagrange multiplier method. To achieve this, we applied adjoint state inversion on the discretized wave equation in both time domain and frequency domain. Besides, in this article, we introduce reliability tests to show that the inversion is performing as it should be ...

The automatic parametrization of the first derivative of glottal flow is studied. Representatives of the two types of methods used most often for parametrization were tested and compared. The chosen representatives are all based on the Liljencrants–Fant model. As numerous tests were needed for a detailed comparison of the methods, a novel evaluation procedure is used which consists of the follo...
متن کاملEvaluating the Improvement of Partial Discharge Localization Accuracy Using Frequency Response Assurance Criterion
Partial Discharge (PD) is the most important source of insulation degradation in power transformers. In order to prevent catastrophic failures in transformers, PDs need to be located as soon as possible so that maintenance measures can be taken in time. Due to the structural complexity of windings, locating the PD source inside a transformer winding is not a simple task. In this paper, the effi...
