Unnatural phonology

This paper addresses one of the most contested issues in phonology: the derivation of phonological typology. I present a new model for deriving phonological typology within the Channel Bias approach. First, a new subdivision of natural processes is proposed: non-natural processes are divided into unmotivated and unnatural.  I propose a new diachronic model for explaining unnatural phenomena: the Blurring Process. Additionally, I provide a proof establishing the minimal sound changes required for an unmotivated/unnatural process to arise. The Blurring Process and Minimal Sound Change Requirement result in a model that probabilistically predicts typology within the Channel Bias approach. This paper also introduces the concept of Historical Probabilities of Alternations (Pχ) and presents a groundwork for their estimation called Bootstrapping Sound Changes. The ultimate goal of the new model is to quantify the influences of Channel Bias on phonological typology.
