Model for phonetic changes driven by social interactions

We propose a stochastic model to study phonetic changes as an evolutionary process driven by social interactions between two groups of individuals with different phonological systems. Particularly, we focus on the changes in the place of articulation, inspired by the drift /\mathrm{\ensuremath{\Phi}}/\ensuremath{\rightarrow}/\mathrm{h}/observed in some words of Latin root in the Castilian language. In the model, each agent is characterized by...
