Abstract

ABSTRACT Purpose: To review the literature regarding prosodic acoustic features found in communicative attitudes related to confidence, certainty, and persuasion. Method: A systematic review was carried out in the databases VHL, Web of Science, Science Direct, SciELO, and SCOPUS with no temporal restriction. Data Extraction: The data from each article was extracted based on the STROBE Statement checklist. To analyze the prosodic variables, the data were subdivided according to Couper-Kuhlen’s (1986) theoretical assumptions, and the variables were grouped into “temporal organization of speech,” “intensity,” and “pitch”. Conclusion: The data suggested that there are relevant but not consensual variables to characterize a persuasive speech and some variables can be considered as positive, negative, or neutral in different language contexts. The variables that stand out as relevant and are characteristic of the persuasive or confidant speech were faster speech speed and higher intensity. The only negative variable that stood out regarding persuasion was the increase in pitch.

说服的声学:自信交际态度的韵律特征的系统回顾

摘要目的:回顾与自信、确定性和说服相关的交际态度的韵律声学特征的文献。方法:采用无时间限制的VHL、Web of Science、Science Direct、SciELO和SCOPUS数据库进行系统综述。数据提取:根据STROBE Statement核对表提取每篇文章的数据。为了分析韵律变量，我们根据Couper-Kuhlen(1986)的理论假设对数据进行细分，将变量分为“言语的时间组织”、“强度”和“音高”。结论:数据表明，有相关的但不是共识的变量来表征一个有说服力的演讲，一些变量在不同的语言语境中可以被认为是积极的，消极的或中性的。有说服力的或有自信的演讲中，与之相关且具有特征的变量是更快的语速和更高的强度。在说服方面，唯一突出的负面变量是音调的增加。
