This study examines the phonetic realisation of the falling nuclear pitch accent that marks corrective focus statements and wh-questions in Russian. An interactive dialogue-reading task elicited acoustic data from speakers of two regional varieties: Central Standard Russian spoken in Moscow (CSR), and Northern Standard Russian spoken in urban areas of the Vologda region (NSR). The two varieties differ in patterns of vowel reduction; while CSR is characterised by lengthening of immediately pretonic vowels, shorter vowels are observed in this position in NSR. Moscow Russian is also reported to display optional extra-early alignment of high turning points in falling accent, associating F0 peaks with the immediately pretonic syllable. Our data provides the first evidence that falling accents in NSR do not demonstrate the same tendency. The Vologda subjects tended to align the high turning point significantly later than the Muscovites, and the pitch maximum was rarely reached before the stressed vowel. Two possible interpretations of these findings are proposed. First, the observed alignment differences can be treated as an outcome of tune-text negotiation, with the option to associate the H target of the bitonal nuclear accent with the pretonic syllable available in Standard Russian, only if the first prestressed vowel is phonetically long. In addition, the NSR data bears resemblance to recent findings concerning an archaic northern dialect with nuclear monotonal H* instead of the bitonal H*+L/H+L* attested in Standard Russian. Therefore, it is suggested that the alignment pattern observed in NSR could be a relic of the archaic monotonal northern nuclear accent transformed under the influence of the dominant standardised variety.

这项研究检查了在俄语中标记纠正焦点陈述和 wh 问题的下降核音高重音的语音实现。交互式对话阅读任务从两个区域变体的扬声器中获取声学数据：莫斯科使用的中央标准俄语 (CSR) 和沃洛格达地区城市地区使用的北方标准俄语 (NSR)。这两个变体的元音减少模式不同；虽然 CSR 的特点是立即前调元音变长，但在 NSR 的这个位置观察到较短的元音。据报道，莫斯科俄语还显示降重音中高转折点的可选超早期对齐，将 F0 峰值与立即前调音节相关联。我们的数据提供了第一个证据，表明 NSR 中的口音下降并没有表现出同样的趋势。沃洛格达人比莫斯科人更倾向于对齐高音转折点，并且在重读元音之前很少达到音高最大值。提出了对这些发现的两种可能的解释。首先，观察到的对齐差异可以被视为曲调文本协商的结果，只有当第一个预重音元音在语音上很长时，才可以选择将双调核重音的 H 目标与标准俄语中可用的前调音节相关联。此外，NSR 数据与最近关于核单调 H* 而非标准俄语证明的双调 H*+L/H+L* 的古代北方方言的发现相似。所以，
