Turbulence and phonology

Abstract

In this paper we aim to provide an account of some of the phonological patterns involving turbulent sounds, summarizing material we have published previously and results from other investigators. In addition, we explore the ways in which sounds pattern, combine, and evolve in language and how these patterns can be derived from a few physical and perceptual principles which are independent from language itself (Lindblom 1984, 1999) and which can be empirically verified (Ohala and Jaeger 1986). This approach should be contrasted with that of mainstream phonological theory (i.e. phonological theory within generative linguistics) which primarily considers sound structure as motivated by “formal” principles or constraints that are specific to language, rather than relevant to other physical or cognitive domains. For this reason, the title of this paper is meant to be ambiguous. The primary sense of it refers to sound patterns in languages involving sounds with turbulence, e.g. fricatives and stops bursts, but a secondary meaning is the metaphorical turbulence in the practice of phonology over the past several decades. We shall treat the latter topic first.
