Voice source analysis using biomechanical modeling and glottal inverse filtering

چکیده
This paper studies the use of glottal inverse filtering together with a biomechanical model of the vocal folds to simulate the glottal flow waveform. The glottal flow waveform is first estimated by inverse filtering the acoustic speech pressure signal of natural speech. The estimated glottal flow is used as a template in an optimization process which searches for a set of parameters for a deterministic vocal fold model such that the model output reproduces the estimated glottal flow. The results indicate that the method can reproduce the main deterministic components of the glottal flow signal with good accuracy.

Parameterisation Methods of the Glottal Flow Estimated by Inverse Filtering
Estimation of the source of voiced speech, the glottal volume velocity waveform, with inverse filtering involves usually a parameterisation stage, where the obtained flow waveforms are expressed in numerical forms. This stage of the voice source analysis, the parameterisation of the glottal flow, is discussed in the present paper. The paper aims to give a review on the different methods develop...

OBJECTIVE The goal of the study is to use physical modelling of voice production to assess the performance of an inverse filtering method in estimating the glottal flow from acoustic speech pressure signals. METHODS An automatic inverse filtering method is presented, and speech pressure signals are generated using physical modelling of voice production so as to obtain test vowels with a known...
متن کاملAdaptive inverse filtering for high accuracy estimation of the glottal source
An adaptive, pitch-synchronous analysis method is proposed for the simultaneous estimation of vocal tract and voice source parameters from speech waveforms. A time varying autoregressive model with exogenous input (ARX) is chosen for vocal tract modeling because of the capability of such a model for characterising both the formants and antiformants of the vocal tract. The Liljencrants-Fant mode...
متن کاملA toolkit for voice inverse filtering and parametrisation
Voice inverse filtering is a process in which the effects of the vocal tract are cancelled from the speech signal to estimate the airflow through the glottis. Although inverse filtering has many applications in both research and clinical examination of voice production, few voice inverse filtering software packages exist. In the present paper, we propose a flexible software package, HUT Voice S...
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...
