This paper presents both distributional and acoustic phonetic evidence for iambic stress in Tetsǫ́t'ıné (ISO: CHP), a Dene (Athapaskan) language with contrastive vowel length and four contrastive tones. In our acoustic study, we find that the primary correlate of stress in Tetsǫ́t'ıné is duration, whereas intensity plays a secondary but statistically significant role. There was no statistically significant effect on F0 in our results. We discuss our results in relation to several proposals regarding the typology of stress systems. Based on the Functional Load Hypothesis (Berinstein 1979) and Dispersion Theory (Flemming 1995, 2001), we find that our results are to some extent unexpected. We suggest that our results are most consistent with the Iambic–Trochaic Law (Hayes 1995), which predicts that iambic stress systems prefer to use duration as their primary stress correlate.

本文介绍了 Tetsǫ́t'ıné（ISO：CHP）中抑扬格重音的分布和声学语音证据，Tetsǫ́t'ıné 是一种具有对比元音长度和四个对比音调的 Dene（Athapaskan）语言。在我们的声学研究中，我们发现 Tetsǫ́t'ıné 中压力的主要相关因素是持续时间，而强度起着次要但具有统计学意义的作用。在我们的结果中，F0 没有统计学上的显着影响。我们讨论了关于压力系统类型学的几个建议的结果。基于功能负荷假设（Berinstein 1979）和分散理论（Flemming 1995，2001），我们发现我们的结果在某种程度上是出乎意料的。我们建议我们的结果与 Iambic-Trochaic 定律最一致 (Hayes 1995)，
