Abstract

Avatars and Artificial Actors in Virtual Environments can be controlled by speech, as an alternative to motion capture techniques. In this paper, we discuss some specific requirements for the successful implementation of speech-based control of guided actors. We describe our sublanguage approach to speech-based control and its associated parsing techniques, based on lexicalised grammars. After an introduction to the REALISM animation software, we report work in progress in the real-time processing of spoken commands based on the integration of speech processing in the REALISM control loop. We conclude by discussing the possible impact of voice-controlled artificial actors in interactive systems.
