Voice, trust, and machines: a decade of research

My research on how voice design shapes trust in AI advisors — begun as a 2016 thesis, now in review at the International Journal of Social Robotics (with C. Fausett & D. Nathan-Roberts). Medium pitch and fast speech measurably raise trust; people defer to machines more on functional decisions than social ones; and people conform to confident, explained recommendations regardless of accuracy — which should worry all of us building explainable AI.

The full piece isn’t published yet — this is the summary.
