About
Werner Verhelst is a pioneering researcher at the intersection of affective computing, social robotics, and human-robot interaction (HRI). His work centers on enabling machines to understand and express human emotion through speech and non-verbal vocalizations, with a particular focus on child-robot communication. Verhelst’s major contributions include the development of Probo, a huggable social robot designed for hospital settings, and the creation of the EMOGIB database—a collection of emotional gibberish speech that allows robots to convey affect without semantic content. His seminal 2007 paper on the robustness of supervised machine learning for emotion classification in speech has garnered over 130 citations, establishing a benchmark in the field. Verhelst also advanced conversational systems for the Nao robot, integrating speech recognition, interpretation, and generation for child-robot interaction. His work on semantic-free utterances (SFUs) has been widely recognized, with a 2015 review paper accumulating nearly 100 citations. Through these efforts, Verhelst has shaped how robots can engage socially and emotionally with humans, particularly in therapeutic and educational contexts.
