Abstract :
The placement of an artificial larynx forward in the vocal tract, which results in a very different system from the normal larynx-vocal tract configuration, is considered. The consequences of this excitation relocation are studied. It is found that zeros are introduced into what is otherwise modeled as an all-pole system
