In this paper, syllable duration (Vowel-to-Vowel unit) and F0 variation are analyzed as cues to distinguish the prosodization of prepositional clitic-host sequence from a syllable within a prosodic word in Brazilian Portuguese (BP). A production task was created to assess 1) whether the syllable production time helps to identify a clitic boundary and a word boundary and 2) whether the F0 configuration aligned to a clitic syllable differs from the F0 configuration aligned to a syllable in a word boundary. The results show that: 1) the syllable duration measurement supports the hypothesis that there is no distinction between prepositional clitics and a syllable which is part of a prosodic word (PW); 2) the pitch range of tonal events associated to the syllable that bears the PW boundary differs from that associated to the syllables that bear a clitic-host sequence boundary. Based on these results we argued that the prepositional clitics are prosodized as a syllable adjoined to its host. This interpretation leads us to suggest that the relevant domain for prepositional clitic prosodization is between PW and PPh (Phonological Phrase) in BP.

巴西葡萄牙语介词连词和韵律词的韵律化：语音线索调查

在本文中，音节持续时间（元音到元音单元）和F0变化被分析为区分巴西葡萄牙语（BP）韵律词中的介词附着体-宿主序列的韵律化的线索。创建了一个生产任务来评估 1) 音节生产时间是否有助于识别附着体边界和单词边界，以及 2) 与附着体音节对齐的 F0 配置是否不同于与单词边界中的音节对齐的 F0 配置。结果表明：1）音节时长测量支持了介词连词与作为韵律词（PW）一部分的音节之间没有区别的假设；2) 与带有 PW 边界的音节相关联的音调事件的音高范围不同于与带有 clitic-host 序列边界的音节相关联的音调事件的音高范围。基于这些结果，我们认为介词连词被韵律化为与其宿主相邻的音节。这种解释使我们认为介词附着体韵律化的相关域在 BP 中的 PW 和 PPh（语音短语）之间。
