One voice does not fit all when it comes to virtual assistants like Siri and Alexa, according to researchers who examined how customization and perceived similarity between user and voice assistant (VA) personalities affect user experience. They found a strong preference for extroverted VAs -- those that speak louder, faster and in a lower pitch. They also found that increasing personality similarity by automatically matching user and VA voice profiles encouraged users to resist persuasive information ..read more

New framework for using AI in health care considers medical knowledge, practices, procedures, values
ScienceDaily
by
18h ago
  Health care organizations are looking to artificial intelligence (AI) tools to improve patient care, but their translation into clinical settings has been inconsistent, in part because evaluating AI in health care remains challenging. In a new article, researchers propose a framework for using AI that includes practical guidance for applying values and that incorporates not just the tool's properties but the systems surrounding its use ..read more

Researchers have discovered that a part of the brain associated with working memory and multisensory integration may also play an important role in how the brain processes social cues. Previous research has shown that neurons in the ventrolateral prefrontal cortex (VLPFC) integrate faces and voices -- but new research shows that neurons in the VLPFC play a role in processing both the identity of the 'speaker' and the expression conveyed by facial gestures and vocalizations ..read more
