| Evaluating Synthesised Prosody In Simulations Of An Automated Telephone Enquiry Service (2007) | |||||||||||||||
Abstract | |||||||||||||||
| Dialogue material has been collected using bionic Wizard-of-Oz simulations of an automated voice-driven dialogue system; system turns, using rule-based speech synthesis, were systematically varied for both text and prosody. In a separate pilot experiment, subjects evaluated the system turns on a number of parameters. While they did not always clearly differentiate between the different conditions, they seemed to associate the "enhanced" prosody, preferred in an earlier laboratory experiment, with a more likeable personality. Keywords: prosody, synthesis, dialogue, evaluation, simulation 1. INTRODUCTION In the voice-operated dialogue system being developed in the SUNDIAL project, concentrating on a "flight enquiries" application, voice output for British English is provided by the Infovox text-to-speech synthesis system. The prosodic component has been adapted and expanded to optimise it for interactive dialogue as opposed to reading aloud. The selection of prosodic patterns is infor... | |||||||||||||||
