AVATAR Project

In the AVATAR project, we develop and demonstrate virtual characters (embodied conversational agents) that can play the role of a police officer or a witness in a police interview. The virtual interview platform for training interview skills integrates the speech recognizer developed in the NLSpraak project, a social agent platform (ASAP) for behavior generation, a dialogue module, text-to-speech generation and virtual humans.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

Some prerequisites are needed before installing the project.

  • Apache ActiveMQ is an open source messaging server used in communication between the ASAP realiser and the Unity AVATAR.

    ActiveMQ can be installed from the Apache website Apache ActiveMQ Getting Started.

  • Fluency is a multilingual Text-to-Speech Synthesis platform for Dutch. Fluency is optional and only used for Dutch TTS synthesis, if English TTS synthesis is used, Fluency is NOT needed.

    Fluency can be installed from the Fluency website Fluency TTS 8.0.

  • MaryTTS is an open-source, multilingual Text-to-Speech Synthesis platform. MaryTTS should be installed by default on your system.

    Otherwise MaryTTS can be installed from the MaryTTS website The MARY Text-to-Speech System Introduction.
