Speech rate in the expression of anger: a study with spontaneous speech material

The study of the acoustic expression of emotion is, in general, the analysis of whether prosodic variables such as intonation (F0), speech rate, pauses, rhythm, intensity and duration, are reliable clues for the characterization of the emotional states of the speaker. The present paper aims to verify whether an association exists in Brazilian Portuguese between the basic emotion of “anger” and the prosodic variable “speech rate”, as the literature often suggests there is for other languages. The corpus consisted of fragments of spontaneous speech recorded from a radio program. The fragments were selected on the basis of a perceptual test. For the production analysis, only excerpts that were identified by more than 75% of the participants of the perceptual test as associated to the categories “anger” and “neutral” were selected. The results demonstrated that, for the data that were used for the analysis, there is a general reduction in speech rate when utterances are associated with the emotion of “anger”, if compared to utterances spoken in a “neutral” mode by the same speaker, contrary to what literature often indicates for other languages.
