This paper argues that tone-driven epenthesis is possible in tonal languages. In Wamey, an epenthetic [ə] is inserted to host a high tone in two contexts: first, to host a tone which would otherwise be left floating due to a restriction on rising tones (/cv̀cⒽ/ maps to [cv̀cə́] due to a ban *[cv̌c]); and second, to host a tone which is introduced by word-level morphology but is restricted from associating across a stem boundary. These patterns cannot be attributed to syllable phonotactics, which freely allow all consonants in the coda position. We assemble the evidence for tone-driven epenthesis, focusing on the distribution of final [ə] in lexical stem structure and [ə]-alternating suffixes. A simple OT analysis derives [ə]-epenthesis, utilising common constraints (e.g. *Rise, OCP(H), etc.) together with constraints against associating tone across prosodic boundaries. In total, Wamey epenthesis exemplifies the cultivation of segmental environments for the purpose of realising pitch targets.

Wamey 中的音调驱动插音

本文认为，声调驱动的插音在声调语言中是可能的。在 Wamey 中，插入了一个附加词 [ə] 以在两种情况下承载高音：首先，承载一个音调，否则由于对升调的限制（/cv̀cⒽ/ 映射到 [cv̀cə́] 由于禁令 *[cv̌c]); 其次，承载由词级形态学引入但不能跨词干边界关联的语调。这些模式不能归因于音节语音策略，它自由地允许尾声位置的所有辅音。我们收集了声调驱动的插入词的证据，重点关注词干结构中词尾 [ə] 和 [ə]-交替后缀的分布。一个简单的 OT 分析推导出 [ə]-epenthesis，利用共同的约束（例如 *上升, OCP(H) 等）以及对跨越韵律边界的关联音调的约束。总的来说，Wamey epenthesis 举例说明了为实现音调目标而培养分段环境。
