A theoretical framework for speech reduction is outlined in which 'coarticulation' and 'articulatory control' operate on sequences of 'opening-closing gestures' in linguistic and communicative settings, leading to suprasegmental properties - 'articulatory prosodies' - in the acoustic output. In linking this gestalt perspective in speech production to the role of phonetic detail in speech understanding, this paper reports on perception experiments that test listeners' reactions to varying extension of an 'articulatory prosody of palatality' in message identification. The point of departure for the experimental design was the German utterance ich kann Ihnen das ja mal sagen 'I can mention this to you' from the Kiel Corpus of Spontaneous Speech, which contains the palatalized stretch [k̟(h)ε̈n(j)n(j)əs] for the sequence of function words /kan i.n(kə)n das/ kann Ihnen das. The utterance also makes sense without the personal pronoun Ihnen. Systematic experimental variation has shown that the extent of palatality has a highly significant influence on the decoding of Ihnen and that the effect of nasal consonant duration depends on the extension of palatality. These results are discussed in a plea to base future speech perception research on a paradigm that makes the traditional segment-prosody divide more permeable, and moves away from the generally practised phoneme orientation.
本文概述了一个语音缩减的理论框架，其中“协同发音”和“发音控制”在语言和交际环境中的“开合手势”序列上起作用，从而在声学输出中产生超音段特性——“发音韵律”。在将语音产生中的这种格式塔观点与语音理解中语音细节的作用联系起来时，本文报告了一些感知实验，这些实验测试了听众在信息识别中对“腭化发音韵律”不同扩展的反应。实验设计的出发点是来自基尔自然口语语料库的德语句子ich kann Ihnen das ja mal sagen，意思是“我可以向您提及此事”，其中功能词序列/kan i.n(kə)n das/ kann Ihnen das包含腭化音段[k̟(h)ε̈n(j)n(j)əs]。没有人称代词Ihnen时，这个句子也说得通。系统的实验变化表明，腭化程度对Ihnen的解码有非常显著的影响，并且鼻辅音时长的影响取决于腭化的扩展。本文呼吁未来的语音感知研究基于一种范式展开讨论，这种范式能使传统的音段-韵律划分更具渗透性，并摆脱普遍采用的音素取向。
