In a variety of Brazilian Portuguese in contact with Veneto, variable vowel reduction in clitic position can be partially accounted for by the phonotactic profile of clitic structures. We show that, when phonotactic profile is controlled for, vowel reduction is statistically more frequent in non-pronominal than in pronominal clitics, which indicates that these clitic types are represented in separate prosodic domains. We propose that this difference in frequency of reduction between clitic types is only possible due to contact with Veneto, which, unlike standard BP, does not exhibit vowel reduction in clitic position. Contact thus provides speakers with the possibility of producing clitic vowels without reduction, and the resulting variation is used to signal prosodic distinctions between clitic types. We show that the difference in frequency of reduction is larger for older speakers, who are more proficient in Veneto and use the language regularly.

音韵变化和韵律表示：葡萄牙语-威尼托联系中的客套话

在与威尼托语接触的各种巴西葡萄牙语中，阴蒂位置的可变元音减少可以部分由阴蒂结构的音位分布来解释。我们表明，当控制音素分布时，非代词中元音减少在统计上比代词 clitics 中的频率更高，这表明这些 clitic 类型在不同的韵律域中表示。我们提出，阴蒂类型之间减少频率的这种差异仅可能是由于与威尼托的接触，与标准 BP 不同，它不会在阴蒂位置表现出元音减少。因此，接触为说话者提供了在不减少的情况下产生阴蒂元音的可能性，并且由此产生的变化用于表示阴蒂类型之间的韵律区别。
