This paper aims to shed light on the textbook description of ejective production through an analysis of the articulatory measures intraoral pressure and larynx height in a data set of phonological Georgian ejectives and epiphenomenal German ejectives. By comparing articulatory mechanisms for ejective production in these two languages, we aim to learn about how ejectives gain phonological status in a language. 14 female German speakers and 13 female Georgian speakers are recorded in a multi-channel experimental set-up. We collect intraoral pressure (IOP) data, an electroglottographic signal and larynx trace using a dual-channel electroglottograph, as well as audio data. We control for place of articulation, vocalic context, word and sentence position, as well as for plosive duration in our analysis. Generalized additive mixed-models are used for statistical analysis. In Georgian, larynx height highly depends on the word and sentence position of the ejective. We find evidence for the hypothesis that pressure buildup after oral closure may be realized by a pulmonic airstream in both Georgian and German ejective production. Sentence-internal Georgian ejectives are produced with lower IOP peak and less steep IOP increase than sentence-initial ejectives. Epiphenomenal ejectives in German are not produced with raised larynx and show lower average IOP than plosives in control conditions.

本文旨在通过对语音格鲁吉亚喷射和附带现象德国喷射数据集中的发音测量口内压力和喉部高度的分析，阐明喷射产生的教科书描述。通过比较这两种语言中弹射产生的发音机制，我们旨在了解弹射如何在语言中获得语音状态。14 位女性德语演讲者和 13 位女性格鲁吉亚演讲者被记录在多通道实验设置中。我们使用双通道电声门图仪收集口内压力 (IOP) 数据、电声门信号和喉部轨迹，以及音频数据。我们在分析中控制发音位置、语音上下文、单词和句子位置以及爆破音持续时间。广义加性混合模型用于统计分析。在格鲁吉亚语中，喉部高度高度取决于喷射词的单词和句子位置。我们找到证据支持以下假设：在格鲁吉亚和德国的喷射生产中，口腔闭合后的压力增加可能是由肺气流实现的。句子内部的格鲁吉亚语喷射器产生的眼压峰值较低，眼压增加的陡峭程度低于句子初始喷射器。德语中的副现象喷射不是在喉部隆起的情况下产生的，并且在控制条件下显示出比爆破声更低的平均眼压。我们找到证据支持以下假设：在格鲁吉亚和德国的喷射生产中，口腔闭合后的压力增加可能是由肺气流实现的。句子内部的格鲁吉亚语喷射器产生的眼压峰值较低，眼压增加的陡峭程度低于句子初始喷射器。德语中的副现象喷射不是在喉部隆起的情况下产生的，并且在控制条件下显示出比爆破声更低的平均眼压。我们找到证据支持以下假设：在格鲁吉亚和德国的喷射生产中，口腔闭合后的压力增加可能是由肺气流实现的。句子内部的格鲁吉亚语喷射器产生的眼压峰值较低，眼压增加的陡峭程度低于句子初始喷射器。德语中的副现象喷射不是在喉部隆起的情况下产生的，并且在控制条件下显示出比爆破声更低的平均眼压。
