Artificial intelligence voice gender, gender role congruity, and trust in automated vehicles.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Existing research on human-automated vehicle (AV) interactions has largely focused on auditory explanations, with less attention to how voice characteristics shape user trust. This paper explores the influence of gender similarity between users and AV voices and the role of gender-role congruity rooted in societal stereotypes on cognitive and affective trust in AVs. Findings reveal that gender-role congruity moderates the relationship between gender similarity and trust. When an AV's voice gender aligns with its expected role, gender similarity enhances cognitive and affective trust. However, when gender roles were not congruent, the trust-enhancing effect of gender similarity diminishes. These findings highlight the importance of considering gender in AV voice design for conveying critical driving information and reveal how societal stereotypes shape AV design. The study offers insights for enhancing user trust and acceptance of AV technology, suggesting future research directions for developing AV systems that avoid reinforcing social biases.
