Emotional Variation in Speech-Based Natural Language Generation
Michael Fleischman, Eduard H. Hovy · Natural Language Generation · 2002
We present a framework for handling emotional variations in a speech-based natural language system for use in the MRE virtual training environment. The system is a first step toward addressing issues in emotion-based modeling of verbal communicative behavior. We cast the problem of emotional generation as a distance minimization task, in which the system chooses between multiple valid realizations for a given input based on the emotional distance of each realization from the speaker’s attitude toward that input.
