ELOQUENCE is dedicated to advancing collaborative voice/chat bots through innovative technology research and development. We aim to understand and transform unstructured dialogues into explainable, safe, knowledge-grounded, trustworthy, and bias-controlled language models. Our technology goals include self-learning, adaptability across languages and use-cases, sustainability with new computational frameworks, and serving as a guide for European citizens, particularly in safety-critical applications. Our project leverages prior successes in conversational agents, including non-EU-developed Large Language Models (LLMs). We collaborate with European enterprises and validate our technology in safety-critical scenarios like emergency services as well as smart home assistants for less risky autonomous systems. ELOQUENCE focuses on context-aware conversational AI in diverse settings, with an interdisciplinary team including experts in various fields. Our project emphasizes sustainability, open science, and addressing ethical and societal concerns, including bias mitigation.
