Abstract
Reduced articulatory precision is common in speech, but for dialog its acoustic properties and pragmatic functions have been little studied. We here try to remedy this gap. This technical report contains content that was omitted from the journal article (Ward et al. 2024, submitted). Specifically, we here report 1) lessons learned about annotating for perceived reduction, 2) the finding that, unlike in read speech, the correlates of reduction in dialog include high pitch, wide pitch range, and intensity, and 3) a baseline model for predicting reduction in dialog, using simple acoustic/prosodic features, that achieves correlations with human perceptions of 0.24 for English, and 0.17 for Spanish. We also provide examples of additional possible pragmatic functions of reduction in English, and various discussion, observations and speculations

减少发声精确度在 speech 中很常见，但在对话中，对其音学和语用功能的研究还很少。在这里，我们试图弥补这个空白。本技术报告包含了 journal 文章中省略的内容（Ward 等人，2024 年提交）。具体来说，我们在这里报道了关于为感知减少的教训（1）以及对话中减少的关系因素（2），包括高音、宽音域和强度，并且用简单的声学/语调特征预测对话中减少的基准模型，其与人类对英语的感知的相关系数为 0.24，对西班牙语的感知的相关系数为 0.17。我们还提供了英语中可能具有额外语用功能的减少的例子，以及各种讨论、观察和推测。
