    abstract = "This paper presents a new approach to disentangling inter-dialectal and intra-dialectal relationships within one such group, the Indo-Aryan subgroup of Indo-European. We draw upon admixture models and deep generative models to tease apart historic language contact and language-specific behavior in the overall patterns of sound change displayed by Indo-Aryan languages. We show that a {\textquotedblleft}deep{\textquotedblright} model of Indo-Aryan dialectology sheds some light on questions regarding inter-relationships among the Indo-Aryan languages, and performs better than a {\textquotedblleft}shallow{\textquotedblright} model in terms of certain qualities of the posterior distribution (e.g., entropy of posterior distributions), and outline future pathways for model development."
