One of the central questions in speech production research is to what degree certain structures have an inherent difficulty and to what degree repeated encounter and practice make them easier to process. The goal of this article was to determine the extent to which frequency and sonority distance of consonant clusters predict production difficulties.
We used a tongue twister paradigm to elicit speech errors on syllable-initial German consonant clusters and investigated the relative influences of cluster frequency and sonority distance between the consonants of a cluster on production accuracy. Native speakers of German produced pairs of monosyllabic pseudowords beginning with consonant clusters at a high speech rate.
Error rates decreased with increasing frequency of the consonant clusters. A high sonority distance, on the other hand, did not facilitate a cluster's production, but speech errors led to optimized sonority structure for a subgroup of clusters. In addition, the combination of consonant clusters in a stimulus pair has a great impact on production accuracy.
These results suggest that both frequency of use and sonority distance codetermine production ease, as well as syntagmatic competition between adjacent sound sequences.
言语产生研究中的核心问题之一是特定结构在多大程度上具有内在难度，以及重复接触和练习在多大程度上使它们更易于处理。本文的目的是确定辅音连缀的频率和音响距离对产生困难的预测程度。
我们使用绕口令范式来引发德语音节起始辅音连缀的言语错误，并研究连缀频率和连缀中辅音之间的音响距离对产生准确性的相对影响。以德语为母语的人以高语速说出以辅音连缀开头的单音节伪词对。
错误率随着辅音连缀频率的增加而降低。另一方面，高音响距离并没有促进连缀的产生，但言语错误导致了一组连缀的音响结构优化。此外，刺激对中辅音连缀的组合对产生准确性有很大影响。
这些结果表明，使用频率和音响距离共同决定了产生的难易程度，以及相邻音序列之间的组合竞争。
