Chapter 3. Learning from Humans: How Research on Vocalizations can Inform the Conceptualization of Robot Sound

Authors: Hannah Pelikan and Leelo Keevallik

Abstract: When aiming to design for intuitive interaction, a good understanding of human behavior is essential. In this chapter we dive into studies on how humans use vocalizations and prosody in everyday interaction. Contrasting six examples from human-human and human-robot interaction, we highlight how insights on human practices can inform the design of robot sound in interaction. We present three main lessons, demonstrating that a) both human vocalizations and robot sound are semantically underspecified, b) human sound production is embodied, and robot sound should therefore be analyzed and designed multimodally, and c) sound can be easily adapted for complex participation.
