In this acoustic study, preboundary lengthening (PBL) in Japanese is investigated in relation to the prosodic structure in disyllabic words with different moraic and pitch accent distributions. Results showed gradient progressive PBL effects largely independent of the mora count. The domain of PBL is better explained by the syllable structure than the moraic structure. PBL, however, is attracted toward a non-final moraic nasal, showing some role of the mora. The initial pitch accent does not attract PBL directly, but it suppresses PBL of the final rime as a way of maintaining the relative prominence, showing a language-specific PBL modulation.
在这项声学研究中，考察了日语中的前置边界延长（PBL）与具有不同韵律和音高重音分布的双音节词的韵律结构之间的关系。结果表明，PBL 的影响具有很大的渐进性，与摩拉数无关。PBL 的域比摩拉结构更能通过音节结构来解释。然而，PBL 被吸引到非末位摩拉鼻音上，这表明摩拉起了一定的作用。起始音高重音不会直接吸引 PBL，但它会抑制最后一个韵母的 PBL，以保持相对突出度，这显示了一种特定语言的 PBL 调制。
