摘要概率语音还原在各种语言、声学领域和可预测性的解释中得到了广泛的证明。较少研究的是概率片段删除的分类效应，原则上它受到类似的压力。本文对英语和日语自发性言语语料库中的语段缺失模式进行了探索性研究。词汇层面的分析表明，音素较多、使用频率较高的词汇往往会有更多的片段被删除。音素层面的分析表明，高概率音素比低概率音素更有可能被删除。仅针对日语，该分析还显示了词长、频率和邻域密度对删除概率的影响。综上所述，这些结果表明，几种大规模的概率片段删除模式反映了语音还原的过程，并适用于两种语言。然而，一些模式似乎是特定于语言的，目前还不清楚语言在这方面可以有多大差异，也不清楚有多大差异。这些发现是从我们对提议的可预测性影响的普遍性的理解以及更广泛的概率减少的角度来讨论的。
Abstract Probabilistic phonetic reduction is widely attested in a variety of languages, acoustic domains, and interpretations of predictability. Less well-studied is the categorical effect of probabilistic segment deletion, which in principle is subject to similar pressures. This paper presents the results of an exploratory study into patterns of segment deletion in corpora of spontaneous speech in English and Japanese. Analysis at the word level reveals that words with more phonemes and higher-frequency words tend to have more of their segments deleted. Analysis at the phoneme level reveals that high-probability phonemes are more likely to be deleted than low-probability phonemes. For Japanese only, this analysis also shows effects of word length, frequency, and neighborhood density on deletion probability. Taken together, these results suggest that several large-scale patterns of probabilistic segment deletion mirror the processes of phonetic reduction and apply to both languages. Some patterns, though, appear to be language-specific, and it is not clear to what extent languages can and do differ in this regard. These findings are discussed in terms of our understanding of the universality of proposed predictability effects, and in terms of probabilistic reduction more broadly.
