This study investigates fundamental frequency variations in oxytons, paroxytons and proparoxytons in Brazilian Portuguese in order to set up patterns to reconstruct word contours according to the location of the stressed syllables in the word. It takes into account fundamental frequency contours in Brazilian Portuguese and is meant to contribute to the research on prosodic features for the ongoing project on text-to-speech system for Brazilian Portuguese. A database has been developed to relate prosodic[2], grammatical and acoustic information in the system. One of linguistic levels in the tables of the database in the word. In the arrays of the table which describes the word, among others, the following features can be related: number of syllables, stress pattern, location of the unstressed syllables in relation to the stressed and initial and final fundamental frequency values. The correlation among these features can be used to implement the rules to generate the fundamental frequency word contours.
