This study explores if, and how, the choices made regarding a robot's speaking voice and characteristic body sounds influence viewers' perceptions of its intent i.e., whether the robot's intention is positive or negative. The analysis focuses on robot representations and sounds in three films: "Robots"(2005) [1], "NextGen"(2018) [2], and "Love, Death, and Robots - Three Robots"(2019) [3]. In eight qualitative interviews, five parameters (tonality, intonation, volume, pitch, and speed) were used to understand robot sounds and the participant's perception of a robot's attitude and intentions. The study culminates in a set of recommendations and considerations for human-robot interaction designers to consider while sound coding for body, physiology, and movement.
