Abstract：
UNASSIGNED: This study aimed to investigate the acoustic and electroglottographic (EGG) profiles of Mandarin deception, including global characteristics and the influence of gender.
UNASSIGNED: Thirty-six Mandarin speakers participated in an interactive interview game in which they provided both deceptive and truthful answers to 14 biographical questions. Acoustic and EGG signals of the participants\' responses were simultaneously recorded; 20 acoustic and 14 EGG features were analyzed using binary logistic regression models.
UNASSIGNED: Increases in fundamental frequency (F0) mean, intensity mean, first formant (F1), fifth formant (F5), contact quotient (CQ), decontacting-time quotient (DTQ), and contact index (CI) as well as decreases in jitter, shimmer, harmonics-to-noise ratio (HNR), and fourth formant (F4) were significantly correlated with global deception. Cross-gender features included increases in intensity mean and F5 and decreases in jitter, HNR, and F4, whereas gender-specific features encompassed increases in F0 mean, shimmer, F1, third formant, and DTQ, as well as decreases in F0 maximum and CQ for female deception, and increases in CQ and CI and decreases in shimmer for male deception.
UNASSIGNED: The results suggest that Mandarin deception could be tied to underlying pragmatic functions, emotional arousal, decreased glottal contact skewness, and more pressed phonation. Disparities in gender-specific features lend support to differences in the use of pragmatics, levels of deception-induced emotional arousal, skewness of glottal contact patterns, and phonation types.

摘要：
■本研究旨在调查普通话欺骗的声学和电声耳图（EGG）特征，包括全球特征和性别的影响。
■36位讲普通话的人参加了一个互动访谈游戏，他们为14个传记问题提供了欺骗性和真实的答案。同时记录参与者反应的声学和EGG信号；使用二元逻辑回归模型分析了20个声学和14个EGG特征。
■基频(F0)平均值的增加，强度平均值，第一共振峰（F1），第五共振峰（F5），接触商(CQ)，去污时间商(DTQ)，和接触指数(CI)以及抖动的减少，shimmer,谐波噪声比(HNR)，第四共振峰(F4)与全球欺骗显著相关。跨性别特征包括强度平均值和F5的增加以及抖动的减少，HNR,和F4，而性别特异性特征包括F0平均值的增加，shimmer,F1，第三共振峰，和DTQ,以及女性欺骗的最大F0和CQ下降，男性欺骗的CQ和CI增加，微光减少。
■结果表明，普通话欺骗可能与潜在的语用功能有关，情绪唤醒，声门接触偏度降低，和更多的压力发声。特定性别特征的差异为语用学使用的差异提供了支持，欺骗引起的情绪唤醒水平，声门接触模式的偏度，和发声类型。
