意大利语有两种类型的辅音双发：词汇和句法。意大利语词汇的双发音是对比的，所以两个单词可能只相差一个双发辅音。相比之下，句法双生现象发生在单词边界上，并在特定的上下文中影响单词的初始辅音，例如单词前面存在单音节语素。本研究探讨了意大利语词法和句法双元音的声学关联，探讨了两种类型的双元音在顿音情况下的关联是否相似。结果证实了先前的研究表明，持续时间是一个突出的双音提示，两种类型的辅音结尾都延长，前辅音元音缩短。结果还显示，在大约10%-12%的例子中，存在双停顿-释放爆发，这为意大利语的双音素性提供了强有力的支持。此外，这些爆发的时间暗示了词汇和句法双生的不同规划过程。第二个突发，当出现时，被容纳在句法双生的关闭间隔内，而词汇双生则被额外的突发延长。这表明，句法生成发生在生产计划的后词汇阶段，在时间已经确定之后。
Two types of consonant gemination characterize Italian: lexical and syntactic. Italian lexical gemination is contrastive, so that two words may differ by only one geminated consonant. In contrast, syntactic gemination occurs across word boundaries and affects the initial consonant of a word in specific contexts, such as the presence of a monosyllabic morpheme before the word. This study investigates the acoustic correlates of Italian lexical and syntactic gemination, asking if the correlates for the two types are similar in the case of stop consonants. Results confirmed previous studies showing that duration is a prominent gemination cue, with a lengthened consonant closure and a shortened pre-consonant vowel for both types. Results also revealed the presence, in about 10%-12% of instances, of a double stop-release burst, providing strong support for the biphonematic nature of Italian geminated stop consonants. Moreover, the timing of these bursts suggests a different planning process for lexical vs syntactic geminates. The second burst, when present, is accommodated within the closure interval in syntactic geminates, while lexical geminates are lengthened by the extra burst. This suggests that syntactic gemination occurs during a post-lexical phase of production planning, after timing has already been established.
