New insights into Portuguese central-southern dialects: understanding their present and past forms through acoustic data from stressed vowels

Abstract

This paper presents new acoustic data on Portuguese central-southern dialects, namely on the stressed vowels of the area. The data show important cues for the history of those dialects, as it can be seen that they are much more similar to one another than is traditionally assumed. Acoustic data on Portuguese central-southern dialects are proven to be of significance, hence, acoustic data on Portuguese dialects are increasingly needed in order to allow for better dialectological characterizations of Portuguese since those characterizations have been based only on auditory data until now.
