More and more, humans are engaging with voice-activated artificially intelligent (voice-AI) systems that have names (e.g., Alexa), apparent genders, and even emotional expression; they are in many ways a growing 'social' presence. But to what extent do people display sociolinguistic attitudes, developed from human-human interaction, toward these disembodied text-to-speech (TTS) voices? And how might they vary based on the cognitive traits of the individual user? The current study addresses

Following exposure to the voices, participants completed these ratings for each speaker, as well as the Autism Quotient (AQ) survey, to assess individual differences in cognitive processing style. Results show differences in individuals' ratings of the likeability and human-likeness of the human and AI talkers based on AQ score. Results suggest that humans transfer social assessment of human voices to voice-AI, but that the way they do so is mediated by their own cognitive characteristics. Index Terms: language attitudes, voice-activated artificially intelligent (voice-AI) systems, sociolinguistic competence Individual variation in language attitudes An additional consideration is whether computer personification responses (here, application of language attitudes to voice-AI) might vary across individuals. Individual variation in behavioral responses to speech is well attested: there are differences across people within the same age, social group, and region in how speech patterns are perceived [26] . In particular, variation across listeners has
