Grounding sound change in ideal observer models of perception

Zachary Burchill, T. Florian Jaeger


Abstract
An important predictor of historical sound change, functional load, fails to capture insights from speech perception. Building on ideal observer models of word recognition, we devise a new definition of functional load that incorporates both a priori predictability and perceptual information. We explore this new measure with a simple model and find that it outperforms traditional measures.
