The familiar talker advantage is the finding that a listener's ability to perceive and understand a talker is facilitated when the listener is familiar with the talker. However, it is unclear when the benefits of familiarity emerge and whether they strengthen over time. To better understand the time course of the familiar talker advantage, we assessed the effects of long-term, implicit voice learning on 89 young adults' sentence recognition accuracy in the presence of four-talker babble. A university professor served as the target talker in the experiment. Half the participants were students of the professor and familiar with her voice. The professor was a stranger to the remaining participants. We manipulated the listeners' degree of familiarity with the professor over the course of a semester. We used mixed effects modeling to test for the effects of the two independent variables: talker and hours of exposure. Analyses revealed a familiar talker advantage in the listeners after 16 weeks (∼32 h) of exposure to the target voice. These results imply that talker familiarity (outside of the confines of a long-term, familial relationship) seems to be a much quicker-to-emerge, reliable cue for bootstrapping spoken language perception than previous literature suggested.

复杂噪声中说话者熟悉度对句子识别准确度的影响。

熟悉说话者的优势是发现当听者熟悉说话者时，会促进听者感知和理解说话者的能力。然而，目前尚不清楚熟悉的好处何时出现以及它们是否会随着时间的推移而增强。为了更好地了解熟悉的说话者优势的时间过程，我们评估了长期隐性语音学习对 89 名年轻人在四个说话者胡言乱语的情况下的句子识别准确性的影响。一位大学教授作为实验的目标说话者。一半的参与者是教授的学生，熟悉她的声音。教授对其余的参与者来说是陌生人。我们在一个学期的过程中操纵了听众对教授的熟悉程度。我们使用混合效应模型来测试两个自变量的影响：谈话者和接触时间。分析显示，在接触目标声音 16 周（~32 小时）后，听众具有熟悉的说话者优势。这些结果表明，说话者的熟悉度（在长期的家庭关系范围之外）似乎是比以前的文献建议的引导口语感知更快出现的可靠线索。
