Dynamic Speech Interaction for Robotic Agents

Abstract

Abstract-Research in mobile service robotics aims on development of intuitive speech interfaces for human-robot interaction. We see a service robot as a part of an intelligent environment and want to step forward discussing a concept where a robot does not only offer its own features via natural speech interaction but also becomes a transactive agent featuring other services' interfaces. The provided framework makes provisions for the dynamic registration of speech interfaces to allow a loosely-coupled flexible and scalable environment. An intelligent environment can evolve out of multimedia devices, home automation, communication, security, and emergency technology. These appliances offer typical wireless or stationary control interfaces. The number of different control paradigms and differently lay-outed control devices gives a certain border in usability. As speech interfaces offer a more natural way to interact intuitively with technology we propose to centralize a general speech engine on a robotic unit. This has two reasons: The acceptance to talk to a mobile unit is estimated to be higher rather than to talk to an ambient system where no communication partner is visible. Additionally the devices or functionalities to be controlled in most cases do not provide a speech interface but offer only proprietary access.

Emotion-based Architecture for Social Interactive Robots

“…More information on the mechatronics system can be found in (Hirth & Berns, 2007). Besides this, the dialog system - based on speech synthesis and recognition -explained in (Koch et al, 2007) -is integrated to communicate using verbal speech.…”

Realization of natural interaction dialogs in public environments using the humanoid robot ROMAN

“…The motives and their function are displayed in table I. For the verbal human-robot communication as well as for the deliberately generated non-verbal expressions the dialog system explained in [13] is used. Therefore the dialog description is handed over to the speech engine, gure 4.…”
