University Study Finds Personalized Robot Voices Boost Likability
Researchers at the University of Augsburg are exploring how humanoid robot voices can influence human perception. Led by Professor Sandra Wachter, the project 'EchoSync' is investigating this phenomenon under the guidance of doctoral student Johanna Kuch.
The study uses a gender-ambiguous robot head with various synthetic voices. Participants interacted with the robot using three different voice types: design-congruent, mismatched, and voice-cloned based on their own speech samples. The goal is to determine if a personalized robot voice, specifically one that resembles the user's, increases the likability towards a robot.
The results suggest that both design-congruent and voice-cloned voices were perceived as more likable than randomly chosen voices. Interestingly, users didn't need to recognize their own voice for the voice-cloned option to be well-received. This indicates that voice cloning could be a promising method for creating more likable robot voices, particularly in one-on-one human-robot interactions.
The study at the University of Augsburg's Chair of Human-Centered Artificial Intelligence highlights the potential of personalized robot voices in enhancing human-robot interaction. Further research is needed to confirm these findings and explore the implications for various applications, such as assistive technologies and customer service robots.
