This study investigates the variation in phrase-final f0 movements found in dyadic unscripted conversations in Papuan Malay, an Eastern Indonesian language. This is done by a novel combination of exploratory and confirmatory classification techniques. In particular, this study investigates the linguistic factors that potentially drive f0 contour variation in phrase-final words produced in a naturalistic interactive dialogue task. To this end, a cluster analysis, manual labelling and random forest analysis are carried out to reveal the main sources of contour variation. These are: taking conversational interaction into account; turn transition, topic continuation, information structure (givenness and contrast), and context-independent properties of words such as word class, syllable structure, voicing and intrinsic f0. Results indicate that contour variation in Papuan Malay, in particular f0 direction and target level, is best explained by turn transitions between speakers, corroborating similar findings for related languages. The applied methods provide opportunities to further lower the threshold of incorporating intonation and prosody in the early stages of language documentation.
本研究调查了印度尼西亚东部语言巴布亚马来语中无脚本对话中句末f0调的变化。这是通过探索性和验证性分类技术的新颖结合来完成的。具体而言，本研究调查了在自然互动对话任务中产生的句末单词中可能驱动f0轮廓变化的语言因素。为此，进行了聚类分析、人工标注和随机森林分析，以揭示轮廓变化的主要来源。这些因素包括：考虑对话互动；话轮转换、话题延续、信息结构（已知性和对比性）以及单词的上下文无关属性，如词类、音节结构、语音和固有f0。结果表明，巴布亚马来语中的轮廓变化，特别是f0方向和目标水平，最好通过说话者之间的话轮转换来解释，这证实了相关语言的类似发现。所应用的方法为在语言记录的早期阶段进一步降低纳入语调韵律的门槛提供了机会。
