Comparing the Directivity of a Mouth Simulator and a Simple Physical Model
* Presenting author
For increasing refinement of virtual acoustic environments, a detailed modelling of source directivities is desired. To include human speech in virtual scenarios it is of interest to create appropriate representations of a mouth as a sound source. Physical mouth simulators are available to test telecommunications devices. However, their directivity is invariant and may not represent the directivity of a human mouth accurately. In order to gain flexibility a customizable parametric model has to be employed. As a starting point a simple physical model is considered.In this paper the physical properties of this simple model are compared with that of a mouth simulator.
