The consensus view of conditioned sound changes is that they begin as low-level phonetic biases which become compounded in the production-perception feedback loop (Ohala, 1981; Pierrehumbert, 2002; Blevins, 2004; Bermudez-Otero, 2007, inter alia). I argue against this consensus view that, instead, the conditioning on sound changes is phonological from the very onset of the change. To support this argument, I present a detailed analysis of a conditioned sound change, the raising of /ay/ before voiceless segments in Philadelphia.
