Perception of Attitudinal Meaning in Interrogative Sentences of Brazilian Portuguese

We present here a perceptual analysis of Brazilian Portuguese prosody expressing eleven different attitudes using an interrogative mode. The attitudes are separated between 6 social, and 4 propositional expressions plus a neutral expression, and are performed by two native speakers (a female and a male). An earlier work studied the declarative mode. The aim of the current study is to perceptually evaluate whether the mode (e.g., declarative or interrogative) influences the perception of attitudes. The multimodal perception of the attitudes is compared across modalities. Our results show higher scores for the propositional attitudes, particularly in the audio modality, while visual information is more important for social expressions, regardless of whether the attitudes are performed in the interrogative or declarative mode.
