 # voss -- Complex system model of language change
 
-Vowel Systems Sandbox (VoSS) is open-source software for running simulations. Specifically, VoSS is an agent-based model (ABM) of language in a complex dynamic system (CDS). The agents interact with each other to learn and pass on their vowel inventories while phonetic and phonological changes in the convention (i.e. the vowel phonemic inventory) are tracked. The software is free to anyone interested in seeing vowel systems change in a virtual community of children learning from their parents.

 1. Ohala and Blevins for the mechanisms of change,
 2. Rosner & Pickering for the mechanics of vowel perception and production, and
 3. de Boer and Steels for the general structure of an imitation game in language acquisition.
