The prosodic prediction phenomenon concerns the possibility of a listener to predict what will be said, following the melodic modulation used for the initial part of a full sentence. This prediction concerns the semantic value and/or the syntactic relations in the sentence. The existence of that phenomenon was confirmed for Brazilian Portuguese, considering the relations between main clauses and subordinate adverbial clauses. Using the speech resynthesis process, it was possible to identify the specific fundamental frequency and durational behavior responsible for the predictive value in the main clauses. The implementation of an algorithm which considers that predictive phenomenon in a speech synthesis system will produce more natural final auditory results.
