Word category and prosodic emphasis in dialog modules of speech technology applications

Abstract

The prosodic behavior of word categories in Modern Greek is observed in relation to two keyword-based Speech Technology applications, namely for a Speech Recognition system in the healthcare domain for task-oriented dialogs intended for senior citizens and for the prosodic modelling of utterances produced by a Conversational Agent in a dialog system for consumer complaints. Word categories are evaluated and classified in the two applications, in respect to the types of words contained in each category, their relation to keywords and their effect on the user.
