- The current study tests subjects' vocal alignment toward female and male text-to-speech (TTS) voices presented via three systems: Amazon Echo, Nao, and Furhat. These systems vary in their physical form, ranging from a cylindrical speaker (Echo), to a small robot (Nao), to a human-like robot bust (Furhat). We test whether this cline of personification (cylinder < mini robot < human-like robot bust) predicts patterns of gender-mediated vocal alignment. In addition to comparing multiple systems, this study addresses a confound in many prior vocal alignment studies by using identical voices across the systems. Results show evidence for a cline of personification toward female TTS voices by female shadowers (Echo < Nao < Furhat) and a more categorical effect of device personification for male TTS voices by male shadowers (Echo < Nao, Furhat). These findings are discussed in terms of their implications for models of device-human interaction and theories of computer personification.

- This study examines participants’ vocal accommodation toward text-to-speech (TTS) voices produced by three devices, varying in the extent to which they embody a human form. Thirty eight speakers shadowed words produced by a male and female TTS voice presented across three physical forms: an Amazon Echo smart speaker (least human-like), Nao robot (slightly more human-like), and a Furhat robot (more human-like). Ninety-six independent raters completed a separate AXB perceptual similarity assessment, which provides a holistic evaluation of accommodation. Results show convergence to the voices across all physical forms; convergence is even stronger toward the female TTS voice when presented with the Echo smart speaker form in the female TTS voice, consistent with participants' higher rated likability and lower creepiness of the Echo. We interpret our findings through the lens of communication accommodation theory (CAT), providing support for accounts of speech communication and human–computer interaction frameworks.
