• Abstract: Previous research has shown that a human-like robot's acceptance heavily depends on the setting in which it operates and its ability to perform relevant tasks. This paper, first, reports on how our robot processes natural language to generate a multimodal, verbal response integrating emotional expressions based on an emotion simulation backend. Then, it describes how visitors were invited to speak with our robot in their own language at three different, public locations, where the robot was running continuously for several days. The TAM2 questionnaire results reveal that on average users were motivated to use the robot and found it rather useful and easy to use regardless of the specific location. However, public spaces like the tourist information and the city library seem to be a better fit for our interactive, robotic head than an office environment such as the building authority, where the willingness to interact was lower. Overall, the robot's multi-lingual responses were very much appreciated, but every fifth user found the response time too slow impeding the dialog flow, which remains to be improved in future work.

  The ability to interact with machines using natural human language is becoming commonplace, but expected. In this paper, we chronicle the recent history of this growing field of spoken dialogue with robots. We offer the community three proposals, the first focused on education, the second on benchmarks, and the third on the modeling of language when it comes to spoken interaction with robots.

  We introduce a fully-automated conversation system that leverages large language models (LLMs) to generate robot responses with expressive behaviors. We conduct a pilot study where volunteers chat with a social robot using our proposed system, and we analyze their feedback, conducting a rigorous error analysis of chat transcripts. Most negative feedback was due to automatic speech recognition (ASR) errors which had limited impact on conversations.

  We focus on cognitive robots, which have some knowledge-based models of the world and operate by reasoning and planning with this model. Our goal in this research is to translate natural language utterances into this robot's formalism. We do so by combining off-the-shelf SOTA language models, planning tools, and the robot's knowledge-base for better communication.
