魅力言语受语言和说话风格的影响，然而在双语公开演讲中，两者的相对贡献仍不清楚。我们分析了10位政治家在高度可比的跨语言交际情境下，用卢森堡语和法语向听众发表的自发言语。从400个话语中，我们提取了41个与声音魅力相关的声学韵律特征，并拟合混合效应模型以分离说话者和语言相关的方差。说话者身份解释了大部分方差，而语言解释的方差较少，但仍显示出系统性差异：法语产出表现出更高的抖动和短语末尾基频，表明一种礼貌、尊重的嗓音，而卢森堡语产出则表现出更强的中频频谱能量，暗示一种更具声音存在感的形象。这些模式与卢森堡语作为非正式身份语言和法语作为高威望制度变体的社会语言学角色一致。
英文摘要
Charismatic speech is shaped by language and speaking style, yet their relative contribution in bilingual public speaking remains unclear. We analyzed spontaneous speeches of 10 politicians who address audiences in Luxembourgish and French, in highly comparable communicative contexts across languages. From 400 utterances, we extracted 41 acoustic-prosodic features linked to vocal charisma and fitted mixed-effects models to separate speaker- and language-related variance. Speaker identity accounted for most variance, whereas language explained less, but still showed systematic differences: French productions showed higher shimmer and phrase-final F0, indicative of a polite, respectful voice, while Luxembourgish productions exhibited stronger mid-frequency spectral energy, suggesting a more vocally present profile. These patterns align with the sociolinguistic roles of Luxembourgish as an informal identity language and French as a high-prestige institutional variety.
