• Resumen

  • Sound variation and change posit an interesting question for the debate on the discrete nature of phonological representations. The investigation of sound variation and change assumes a similar view with regards to the discrete and single nature of phonological representations. This chapter provides a different perspective by adopting the usage-based model in phonology (henceforth, UB-Phonology) presented by Bybee, where regularities of phonological structure are expressed in schemas of networks of association. The representational model adopted by UB-Phonology is Exemplar Theory, which questions earlier ideas on the nature of phonological representations. Frequency effects play an important role in shaping phonological representations. The chapter explores the role of frequency effects by investigating cases of ongoing sound change in Brazilian Portuguese. It then discusses the nature of phonological representations by considering the sociolinguistic, lexical diffusion, and UB-Phonological perspectives.
