研究表明，说话人在表达指称时经常使用不必要的修饰语，这是违反数量准则的。在这项研究中，我们检查了指称表达的产生（例如。G.红色三角形），其中包含一个过度描述（或冗余）的名词前形容词修饰语。这些表达方式与在特定语境中表达的类似表达方式进行了比较，这种语境使得修饰语对于唯一的指称识别是必要的。我们的假设是，扬声器阐明过度描述的修饰语不同于那些用来区分对比对象。结果表明，过度描述的修饰语的持续时间明显短于用于区分两个对象的修饰语。结论集中在如何这些声学差异可以模拟自然语言生成算法，如增量算法，结合概率韵律减少。
Studies have shown that speakers often include unnecessary modifiers when producing referential expressions, which is contrary to the Maxim of Quantity. In this study, we examined the production of referring expressions (e. g. the red triangle) that contained an over-described (or redundant) pre-nominal adjective modifier. These expressions were compared to similar expressions that were uttered in a context that made the modifier necessary for unique referent identification. Our hypothesis was that speakers articulate over-described modifiers differently from those used to distinguish contrasting objects. Results showed that over-described modifiers were significantly shorter in duration than modifiers used to distinguish two objects. Conclusions focus on how these acoustic differences can be modelled by Natural Language Generation algorithms, such as the Incremental Algorithm, in combination with probabilistic prosodic reduction.
