The phonetic/phonological aspects involved in the pronunciation of the post-vocalic s have already been analysed in several works conceming different dialects of Brazilian Portuguese. This paper presents a study of some lexical factors involved in the aspiration of the post-vocalic s in the dialect of Rio de Janeiro as an alternative approach to the phenomenon. It  also reinforces the applicability of the Lexical Diffusion madel to Portuguese.
