声学持续时间和元音减少的程度与单词的出现频率相关。本研究将频率在言语产生中作用的研究拓展到语音同化。测试案例是荷兰语中的退化语音同化。集群从一个语料库的阅读语音更经常被认为是未同化的低频词和完全发声（回归同化）或，出乎意料的是，作为完全无意识（渐进同化）在高频词。频率没有预测的声音分类以上重要的声学线索发声，这表明频率的影响进行分类完全由声学信号。集群持续时间和集群期间的声门振动周期减少，而释放噪声的持续时间增加的频率。这表明说话者减少了对高频词的发音努力，一些声学线索发出更多的声音，而另一些声音则发出更少的声音。更高的频率不仅导致声音减少，而且导致更多的同化。
Acoustic duration and degree of vowel reduction are known to correlate with a word's frequency of occurrence. The present study broadens the research on the role of frequency in speech production to voice assimilation. The test case was regressive voice assimilation in Dutch. Clusters from a corpus of read speech were more often perceived as unassimilated in lower-frequency words and as either completely voiced (regressive assimilation) or, unexpectedly, as completely voiceless (progressive assimilation) in higher-frequency words. Frequency did not predict the voice classifications over and above important acoustic cues to voicing, suggesting that the frequency effects on the classifications were carried exclusively by the acoustic signal. The duration of the cluster and the period of glottal vibration during the cluster decreased while the duration of the release noises increased with frequency. This indicates that speakers reduce articulatory effort for higher-frequency words, with some acoustic cues signaling more voicing and others less voicing. A higher frequency leads not only to acoustic reduction but also to more assimilation.
