RRL: A Rich Representation Language for the Description of Agent Behaviour in NECA

In this paper, we describe the Rich Representation Language (RRL) which is used in the NECA system. The NECA system generates interactions between two or more animated characters. The RRL is a formal framework for representing the information that is exchanged at the interfaces between the various NECA system modules

CYBEREMOTIONS – Collective Emotions in Cyberspace

AbstractEmotions are an important part of most societal dynamics. As with face to face meetings, Internet exchanges may not only include factual information but may also elicit emotional responses; how participants feel about the subject discussed or other group members. The development of automatic sentiment analysis has made large scale emotion detection and analysis possible using text messages collected from the web. We present results of two years of studies performed in the EU Large Scale Integrating Project CYBEREMOTIONS (Collective emotions in cyberspace) Our goal is to understand the role of collective emotions in creating, forming and breaking-up ICT mediated communities and to prepare the background for the next generation of emotionally-intelligent ICT services. Project results have already attracted a lot of attention from various mass media and research journals including the Science and New Scientist magazines. Nine Project teams are organised in three layers (data, theory and ICT output)

VieCtoS - Speech Synthesizer, Technical Overview

This report describes the overall architecture of the speech synthesis module developed for VieCtoS, the Vienna concept-to-speech system for Austrian German. A technical description of the methods used for the representation of inventory elements, their concatenation and the facilities for interpreting and superimposing prosody is presented. An overview of the implementation and the user environment as well as some details concerning program and test design are included in order to facilitate usage and further development. General Overview In the Vienna Concept to Speech (VieCtoS) project (for an overview see [1]) information from a database as input is processed to form an acoustic output---with intonation and phrasing according to the information content. The target language is German, and the synthesizer is template based, with demisyllables recorded from a male speaker of standard An extract from this report titled "Realization of Prosody in a Speech Synthesizer for German" has b..

Generating Emotional Speech With A Concatenative Synthesizer

We describe the attempt to synthesize emotional speech with a concatenative speech synthesizer using a parameter space covering not only f0, duration and amplitude, but also voice quality parameters, spectral energy distribution, harmonics-to-noise ratio, and articulatory precision. The application of these extended parameter set offers the possibility to combine the high segmental quality of concatenative synthesis with a wider range of control settings needed for the synthesis of natural affected speech. 1 INTRODUCTION The quality of synthesized speech is usually measured in terms of intelligibility and naturalness. State of the art synthesizers are well intelligible under regular conditions. Therefore, development has concentrated on the improvement of naturalness. An obvious way to follow is the incorporation of correct and functionally adequate prosody. Another maybe less obvious but very interesting aim is the generation of non-neutral affect. For the English language a system f..
