Discussion points for Beddor:2023
- basic assumptions
  . non-random, systematic phonetic variants underlie sound change
  . innovative speaking and listening, production-perception loop
- how do stable patterns of variation in a speech community become
  unstable patterns that lead to change?
  . (nearly) all changes due to coarticulation and reduction?
  . what about phonetic convergence?
  . errors and misperception not a necessary trigger
- how to identify sound change in progress?
  . static snapshots vs longitudinal observation
  . why this change, why now, why this language/variety?
  . is change in perception ahead of change in production?
  . are there individual leaders of change?
- how does innovative speaking/listening result in new phonetic norms?
- are changes a consequence of universal mechanisms of human speech
  processing (e.g., aerodynamics, quantal regions, prosody??,
  frequency of usage, predictability, multilingualism)
- how to model sound change
  . exemplar models
  . convergence models
  . agent-based models
