This paper presents a perceptual and acoustic analysis of a set of 12 different prosodic attitudes of Brazilian Portuguese, separated between 6 social, 5 propositional plus a neutral expressions. Audio-visual performances of these attitudes by two native speakers are described as well as their recognition by Brazilian listeners. The results show better performances for the propositional attitudes, particularly in the audio modality, while visual information brings the main indices for social expressions.
