Abstract

This paper shows that realistic and coherent vowel systems can emerge from scratch in a population of agents that imitate each other under humanlike constraints of production and perception. The simulation is extended so that populations can change; old agents can be removed, and new agents can be added. In these circumstances vowel systems can also emerge and be preserved. It is shown that sometimes an age structure in the population can improve preservation of the vowel systems.
