Multimodal Human-Autonomous Agents Interaction Using Pre-Trained Language and Visual Foundation Models
Linus Nwankwo, Elmar Rueckert
TL;DR
The paper addresses the challenge of natural and robust human-robot interaction with autonomous agents in real-world environments. It introduces a dual-modality pipeline that combines pre-trained large language models (LLMs), multimodal visual language models (VLMs), and speech recognition (SR) to interpret vocal and textual input and map it to robot actions via a ROS-based execution layer. Key results show vocal command understanding accuracy of 87.55% and command execution accuracy of 86.27%, with an average latency of about 0.89 seconds, while text-based interactions achieve higher nominal accuracy; the approach demonstrates robustness to accent variation and environmental noise by enabling modality switching. The work advances practical HRI by enabling more intuitive, natural interactions and provides a path toward noise-robust, context-aware human-robot collaboration in real-world settings.
Abstract
In this paper, we extended the method proposed in [21] to enable humans to interact naturally with autonomous agents through vocal and textual conversations. Our extended method exploits the inherent capabilities of pre-trained large language models (LLMs), multimodal visual language models (VLMs), and speech recognition (SR) models to decode the high-level natural language conversations and semantic understanding of the robot's task environment, and abstract them to the robot's actionable commands or queries. We performed a quantitative evaluation of our framework's natural vocal conversation understanding with participants from different racial backgrounds and English language accents. The participants interacted with the robot using both spoken and textual instructional commands. Based on the logged interaction data, our framework achieved 87.55% vocal commands decoding accuracy, 86.27% commands execution success, and an average latency of 0.89 seconds from receiving the participants' vocal chat commands to initiating the robot's actual physical action.
