While prosodic boundaries are known to affect the acoustic realization of segments and lexical full tones, no study thus far has examined how the f0 realization of a neutral tone is influenced by different prosodic boundaries. This study set out to fill this knowledge gap by investigating the effect of prosodic boundary on neutral-tone realization in Tianjin Mandarin, a variety which has been reported to exhibit interesting context-dependent f0 variation. Our results showed that the high neutral-tone f0 offset before the low falling tone (Tone 1) does not need to be treated as a special tonal target as claimed in the literature, but rather could be due to the raising effect brought about by the following T1, which can also be observed on the f0 realization of lexical tones. The neutral tone in Tianjin Mandarin has a mid-low tonal target similar to that in Standard Chinese. In addition, by manipulating the prosodic boundary between neutral tone and the following T1, we observed an interesting effect of prosodic boundary on the neutral-tone f0 realization. Specifically, the raising effect due to the following T1 can be blocked by a higher-level prosodic boundary (i.e., a Subject-Predicate boundary) compared to a lower-level prosodic boundary (i.e., a Below-NP boundary). Finally, our study observed both effects of prosodic boundary and focus on tonal implementation. They remain separate mechanisms in speech production, but could interact to modulate the magnitude of f0 changes due to effects of focus and prosodic boundary in neutral-tone f0 realization.

天津普通话中以韵律为条件的中性语调实现

虽然已知韵律边界会影响片段和词汇完整音调的声学实现,但迄今为止,尚无研究检查中性音调的f0实现如何受到不同韵律边界的影响。这项研究旨在通过调查韵律边界对天津普通话中立音实现的影响来填补这一知识空白,据报道该变种表现出有趣的上下文相关的f0变异。我们的结果表明,不需要将低中音(音调1)之前的高中性音f0抵消视为文献中所要求的特殊音调目标,而可能是由于音高带来的提升效果。跟随T1,这也可以在f0实现的语调上观察到。天津普通话的中性语调具有与标准中文类似的中低音调目标。此外,通过操纵中性音调与随后的T1之间的韵律边界,我们观察到韵律边界对中性音调f0实现的有趣影响。具体地,与较低水平的韵律边界(即,低于NP的边界)相比,可以通过较高水平的韵律边界(即,主语-谓语边界)来阻止由于随后的T1引起的提高效果。最后,我们的研究观察了韵律边界的影响并关注音调的实现。它们在语音产生中仍然是独立的机制,但是由于中性音调f0实现中的焦点和韵律边界的影响,它们可以交互作用来调节f0变化的幅度。通过操纵中性音调和随后的T1之间的韵律边界,我们观察到韵律边界对中性音调f0实现的有趣影响。具体地,与较低水平的韵律边界(即,低于NP的边界)相比,可以通过较高水平的韵律边界(即,主语-谓语边界)来阻止由于随后的T1引起的提高效果。最后,我们的研究观察了韵律边界的影响并关注音调的实现。它们在语音产生中仍然是独立的机制,但是由于中性音调f0实现中的焦点和韵律边界的影响,它们可以交互作用来调节f0变化的幅度。通过操纵中性音调和随后的T1之间的韵律边界,我们观察到韵律边界对中性音调f0实现的有趣影响。具体地,与较低水平的韵律边界(即,低于NP的边界)相比,可以通过较高水平的韵律边界(即,主语-谓语边界)来阻止由于随后的T1引起的提高效果。最后,我们的研究观察了韵律边界的影响并关注音调的实现。它们在语音产生中仍然是独立的机制,但是由于中性音调f0实现中的焦点和韵律边界的影响,它们可以交互作用来调节f0变化的幅度。与较低水平的韵律边界(即低于NP边界)相比,较高的韵律边界(即主语-谓语边界)可以阻止由于后续T1引起的提升效果。最后,我们的研究观察了韵律边界的影响并关注音调的实现。它们在语音产生中仍然是独立的机制,但是由于中性音调f0实现中的焦点和韵律边界的影响,它们可以交互作用来调节f0变化的幅度。与较低水平的韵律边界(即低于NP边界)相比,较高的韵律边界(即主语-谓语边界)可以阻止由于后续T1引起的提升效果。最后,我们的研究观察了韵律边界的影响并关注音调的实现。它们在语音产生中仍然是独立的机制,但是由于中性音调f0实现中的焦点和韵律边界的影响,它们可以交互作用来调节f0变化的幅度。
