This article provides individual speakers' acoustic durational data on preboundary (phrase-final) lengthening in Japanese. The data are based on speech recorded from fourteen native speakers of Tokyo Japanese in a laboratory setting. Each speaker produced Japanese disyllabic words with four different moraic structures (CVCV, CVCVN, CVNCV, and CVNCVN, where C stands for a non-nasal onset consonant, V for a vowel, and N for a moraic nasal coda) and two pitch accent patterns (initially-accented and unaccented). The target words were produced in carrier sentences in which they were placed in two different prosodic boundary conditions (Intonational Phrase-final ('IPf') and Intonational Phrase-medial ('IPm')) and two focus contexts (focused and unfocused). The measured raw values of acoustic duration of each segment in different conditions are included in a CSV-formatted file. Another CSV-formatted file is provided with numeric calculations in both absolute and relative terms that exhibit the magnitude of preboundary lengthening across different prominence contexts (focused/unfocused and initially-accented/unaccented). The absolute durational difference was obtained as a numeric increase of preboundary lengthening of each segment produced in phrase-final position versus phrase-medial position (i.e., Δ(IPf-IPm) where 'f' = 'final' and 'm' = 'medial'). The relative durational difference was obtained as a percentage increase of preboundary lengthening in IP-final position versus IP-medial position, which was calculated by the absolute durational difference divided by the duration of the segment in phrase-medial position and then multiplied by 100 (i.e., (Absolute difference/IPm)*100). This article also provides figures that exemplify speaker variation in terms of absolute and relative differences of preboundary lengthening as a function of pitch accent. Some theoretical aspects of the data are discussed in the full-length article entitled "Preboundary lengthening in Japanese: To what extent do lexical pitch accent and moraic structure matter?" [1].
本文提供了关于日语中边界前（短语末尾）延长的单个说话者的声学时长数据。这些数据基于在实验室环境中对14名东京日语母语者的语音记录。每位说话者生成了具有四种不同 moraic 结构（CVCV、CVCVN、CVNCV 和 CVNCVN，其中 C 代表非鼻音起始辅音，V 代表元音，N 代表 moraic 鼻音韵尾）和两种音高重音模式（起始重音和非重音）的日语双音节词。目标词在载体句子中生成，这些句子被置于两种不同的韵律边界条件（语调短语末尾（'IPf'）和语调短语中间（'IPm'））以及两种焦点语境（聚焦和非聚焦）中。不同条件下每个片段的声学时长测量原始值包含在一个CSV格式的文件中。另一个CSV格式的文件提供了绝对和相对术语的数值计算，展示了不同突出语境（聚焦/非聚焦和起始重音/非重音）下边界前延长的程度。绝对时长差异通过短语末尾位置与短语中间位置生成的每个片段的边界前延长的数值增加来获得（即Δ(IPf - IPm)，其中'f' = '末尾'，'m' = '中间'）。相对时长差异通过IP末尾位置相对于IP中间位置的边界前延长的百分比增加来获得，其计算方法是绝对时长差异除以短语中间位置片段的时长，然后乘以100（即(Absolute difference / IPm) * 100）。本文还提供了一些图表，这些图表例证了作为音高重音函数的边界前延长的绝对和相对差异方面的说话者变异。数据的一些理论方面在题为《日语中的边界前延长：词汇音高重音和 moraic 结构在多大程度上起作用？》[1]的全文中进行了讨论。
