The paper deals with optimization process finding such geometrical form of acoustical cavities of the human supraglottal spaces which leads to excitation of predefined ac [...]

Inverse method was used for numerical simulation of acoustic characteristics of a professional musical actor before and after vocal exercises. The geometrical data for a [...]

Results of a voice numerical simulation using finite element (FE) model of acoustic spaces corresponding to the human vocal tract for English vowel / a / are presented. T [...]

The speech audiometry answers the question how a person is able to perceive, differentiate and understand living speech. The first construction attempts of speech audiome [...]

1D and 3D finite element models of supraglottal tract designed for Czech vowel / a / are analyzed. Performed modal analysis is focused on investigation of the influence o [...]

Acoustic speech output in humans is commonly considered to results from a combination of a source of sound energy (e.g. the larynx) modulated by a transfer (filter) funct [...]

The model of the human vocal fold is created with transfer matrix method. The model is made from 32 cylindric or conic elements for Czech vowel /u/. The calculation is ca [...]

The Source-filter theory does not take into account many important circumstances for generating of vowels, e.g. the effects of source on filter. One of these effects is i [...]

A 3D finite element model of the human larynx including the vocal folds was developed. The model enables to take into account phonation position (tension and adduction) o [...]

The study presents three-dimensional finite element (FE) model of flow induced oscillations of the human vocal folds in interaction with acoustic processes in the simplif [...]

Linear two degrees of freedom aero-elastic system for modelling vibrations of human vocal folds was originally developed by which the physiological conditions for so-call [...]

The radiated sound pressure level (SPL) during phonation is known to be mainly regulated by lung pressure and glottal resistance (adduction), at the glottal level. Few re [...]
