This study investigates how listeners perceive the certainty and honesty of speakers based on their speech. Using a data-driven method, the researchers decoded prosodic features (pitch, duration, loudness) driving these perceptions. They found a common prosodic signature underlying both judgments, independent of listeners' conceptual knowledge and native language. This signature automatically impacts word memorization, suggesting an auditory adaptation for detecting unreliability in linguistic interactions.
