Known-Voice Cloning and the Limits of Personality Transfer for Character Design
研究考察熟悉人物克隆声音能否将人格印象迁移到虚拟角色，并在大学现场和线上两项研究中验证。
核心要点
- 零样本语音克隆可把可识别声音赋予虚拟角色，引发社会操控担忧。
- 两项研究分别用学生熟悉的讲师声音、社媒创作者声音测试人格印象迁移。
- 结果显示人格迁移证据有限，效应具有选择性，未跨特质或研究情境泛化。
- 定性反馈表明，判断常受感知人工感以及声音与外观是否匹配影响。
验证范围与局限：验证范围为真实大学场景和线上社区情境中的虚拟角色克隆声音。
英文摘要 (Abstract)
Recent advances in zero-shot voice cloning systems make it possible to reproduce a recognizable voice from a short recording and attach it to arbitrary virtual characters. Prior work suggests that familiar vocal identity can carry over associated personality impressions to new targets such as robots or virtual characters. However, these works have mainly examined familiarity and personalization effects rather than directly testing whether a cloned familiar voice systematically transfers personality impressions to an embodied virtual character. Such transference raises the concern that cloned voices could be used to manipulate people into engaging with virtual characters as capable social actors. Across two studies, we investigated whether personality impressions transfer when a virtual character speaks with the cloned voice of a familiar person. Study 1 examined this question in a real-world university setting using the cloned voice of a lecturer familiar to the participating students. Study 2 examined the same question online using voices of social media content creators and members of their communities. Drawing on the concepts of identity activation, trait transfer, and person reconstruction, we show that evidence of personality transfer was limited in both studies. Observed effects were selective and did not generalize across traits or study contexts. In the online study in particular, recognizable voice identity cues activated expectations about the speaker but did not reconstruct the broader person impression. Qualitative responses further indicated that judgments were frequently shaped by perceived artificiality and by whether voice and appearance fit together. Our findings moderate common concerns that cloned voices straightforwardly manipulate people into perceiving artificial characters as capable social actors.
