Sound in human-robot interaction currently encompasses a wide range of approaches and methodologies that is not easily classified, analyzed, or compared between projects. This edited book covers the state-of-the-art in sound and robotics aiming to collect existing approaches in a combined volume. Collecting chapters from world-leading academic and industry authors, the book explores how robots can communicate with speech, non-verbal audio and through music. The first set of chapters explores how robots use verbal communication, considering the possibilities of speech for human-robot interaction. The second section shifts to the roles of non-verbal communication in HRI, including consequential sound, sonification and audio cues. The third and final section describes current approaches to robotic musicianship and its evaluation. This book is primarily aimed at HRI researchers, ranging from those who have never used sound to those who are very experienced with sound. Alongside robotic researchers this book will present avenues for a diverse range of musicians, composers and sound-designers to be introduced to the world of HRI and learn of potential creative directions in robotics.
