声音说服力、韵律信息论与人际生理同步
从基频包络、停顿熵、听众自主神经耦合到公众演说气场的声学与认知神经科学
Acoustic Persuasion, Prosodic Information Theory and Interpersonal Physiological Synchrony: Pitch Contours, Pause Entropy and Listener Autonomic Coupling in Public Speaking and Leadership
DOI10.5281/zenodo.23753267摘要
同样的文字，用不同的声音说出来，听众对说话者的判断可能很不一样。本书用声学、信息论与认知神经科学考察这种差别，以及围绕它的流行说法哪些有证据。依次讨论：梅拉比安「7%-38%-55%」规则的真实来源与适用范围（只适用于单个词表达好恶、渠道互相矛盾的情形），以及基频、共振峰离散度、谐噪比与语速影响听众判断的实证研究，包括一项单个词研究中可信的韵律原型在词末上扬的发现；香农惊奇度与均匀信息密度假说，以及一个有限容量听者模型（匆忙使关键信息几乎无法编码，关键词前停顿并拉长最好，填充词也有类似停顿的作用，但可能让说话者显得不够有把握）；藤崎模型生成与测量的句末下降与上扬，下倾部分是计划性的，上扬的功能不只是不确定；说话者与听者的大脑耦合与听众之间的心率同步，以及用库拉莫托模型和对照条件区分共同驱动与相互耦合，受试者间相关的循环平移检验；尖叫中 30–150 Hz 振幅调制的粗糙度与谐噪比的计算；心形麦克风近讲效应、信噪比与临界距离。
八章与《礼记·乐记》「凡音之起，由人心生也」及六种心境之声、《鬼谷子》的揣摩与「己默者，静也」、《论语》「君子有三变」与「辞达而已矣」并读，并指出并读的限度；最后给出一份演说与录制前的四步声学核查表，以及一项比较「句末下降 + 关键词前 0.6 秒停顿」与「句末上扬 + 无停顿 + 较快语速」两种韵律版本的预注册双盲随机对照试验方案（主要结局为假设预算中的投资意愿，四位声音演员分层，每组 338 人可分析、招募 398 人，判定规则写成代码）。书中以标注框区分已发表的证据、可运行的 Python 计算（14 段程序，全部核对；书中的声音均为程序合成）、原典与作者的假说。本书讨论如何让真实的内容被听清、被记住，不是用声音技巧操纵听众的方法。

Abstract
The same words spoken in different voices can lead listeners to judge the speaker very differently. This book examines that difference with acoustics, information theory and cognitive neuroscience, and asks which popular claims about it have evidence. It covers the true source and scope of Mehrabian's "7 %–38 %–55 %" rule (it applies only when a single word conveys liking and the channels contradict each other) and empirical research on how fundamental frequency, formant dispersion, harmonics-to-noise ratio and speech rate affect listeners' judgements, including a single-word study in which the trustworthy prosodic prototype rose at the end of the word; Shannon surprisal and the uniform information density hypothesis, with a limited-capacity listener model (rushing leaves key information almost unencoded, a pause before and lengthening of the key word works best, and fillers act somewhat like pauses but may make the speaker seem less sure); final falls and rises generated and measured with the Fujisaki model, declination being partly planned and uptalk serving more functions than uncertainty; speaker–listener brain coupling and heart-rate synchrony among listeners, with the Kuramoto model and control conditions separating common drive from mutual coupling, and a circular-shift test of inter-subject correlation; computation of roughness from 30–150 Hz amplitude modulation in screams and of the harmonics-to-noise ratio; and the proximity effect of cardioid microphones, signal-to-noise ratio and critical distance.
The eight chapters are read beside the Record of Music's "all sound arises from the human heart" and its six sounds of the heart, the Guiguzi's probing and sounding out and "one's own silence is stillness", and the Analects' "the gentleman has three aspects" and "in speech, it is enough to convey the meaning", noting the limits of such a reading. They end with a four-step acoustic checklist for use before speaking or recording and a pre-registered double-blind randomised controlled trial comparing a "final falls + 0.6-second pauses before key words" version with a "final rises + no pauses + faster speech" version of the same pitch (primary outcome willingness to invest from a hypothetical budget, stratified by four voice actors, 338 analysable and 398 recruited per arm, decision rule written as code). Marked boxes separate published evidence, runnable Python calculations (14 programs, all checked; every sound in the book is synthesised), classical sources and the author's hypotheses. The book is about helping true content to be heard and remembered, not about manipulating listeners with vocal technique.
