Negative emotional arousal during conflict has been related to negative outcomes in romantic relationships and degraded quality of family life. Despite its extensive study in psychology, it is still challenging to quantify emotional arousal in a meaningful way with objective indices beyond traditionally-used self-reported scores. We examine the association of acoustic and physiological arousal between...
Observational methods are fundamental to the study of human behavior in the behavioral sciences. For example, in the context of research on intimate relationships, psychologists’ hypotheses are often empirically tested by video recording interactions of couples and manually coding relevant behaviors using standardized coding systems. This coding process can be time-consuming, and the resulting coded...
Motivated by linguistic theories of prosodic categoricity, symbolic representations of prosody have recently attracted the attention of speech technologists. Categorical representations such as ToBI not only bear linguistic relevance, but also have the advantage that they can be easily modeled and integrated within applications. Since manual labeling of these categories is time-consuming and expensive,...
Symbolic representations of prosodic events have been shown to be useful for spoken language applications such as speech recognition. However, a major drawback with categorical prosody models is their lack of scalability due to the difficulty in annotating large corpora with prosodic tags for training. In this paper, we present a novel, unsupervised adaptation technique for bootstrapping categorical...
Prosody is an important cue for identifying dialog acts. In this paper, we show that modeling the sequence of acoustic- prosodic values as n-gram features with a maximum entropy model for dialog act (DA) tagging can perform better than conventional approaches that use coarse representation of the prosodic contour through acoustic correlates of prosody. We also propose a discriminative framework that...
The ability to identify speech acts reliably is desirable in any spoken language system that interacts with humans. Minimally, such a system should be capable of distinguishing between question-bearing turns and other types of utterances. However, this is a non-trivial task, since spontaneous speech tends to have incomplete syntactic, and even ungrammatical, structure and is characterized by disfluencies,...
