ABSTRACT
In this chapter I report on an acoustic study of intervocalic voiceless stops in oral versus nasal contexts in Guarani'. Guarani is a language well-known for its nasal harmony, in which all voiced segments become nasalized and voiceless segments behave transparent. An acoustic comparison of oral and nasal word pairs in Guarani provides information about what effect, if any, nasal harmony has on transparent voiceless stops. In the previous chapter I proposed an analysis of transparency as an opacity effect, producing surface orality of transparent segments in nasal harmony. The findings of the study of Guarani corroborate this result by providing support for the claim that voiceless stops typically surface as oral obstruent stops in nasal spreading domains.
