An independent study highlights the impact of voice analysis in personnel selection and evaluation with a practical and ethical approach
Salamanca, Spain – The University of Salamanca (USAL) has conducted an independent study analyzing the implementation of Layered Voice Analysis (LVA) technology, as applied in the TrueTalent™ tool. Led by Associate Professor of Administrative Law, Daniel Terrón Santos, the report evaluates the features, applications, and benefits of this technology, emphasizing its usefulness in personnel selection and workforce management processes. According to the professor:
“LVA combines voice analysis and specific questionnaires to provide a unique insight into emotional and cognitive states, facilitating ethical and well-founded decisions in human resources.”
The report highlights how this technology analyzes emotional, cognitive, and stress patterns in the voice, serving as a valuable tool to optimize HR processes by offering speed, reliability, and ethical data management.
