Abstract
Vowel System Sandbox is a complex agent-based modelling tool which is intended for linguists and speech researchers to test hypotheses about how vowel sounds are transmitted and used through the generations in a language community, and thus how vowel systems may change over generational time. Written in Python 3, the code repository is on Github and can be run in Linux, Windows 7+ and MacOS. This is the first software that provides a computational model of sound change in language by implementing first principles of speech perception and production.
