While Mixtec languages are well-known for their tonal systems, there remains relatively little work focusing on their consonant inventories. This paper provides an in-depth phonetic description of the consonant system of the Yoloxóchitl Mixtec language (Oto-Manguean, ISO 639-3 code xty), a Guerrero Mixtec variety. The language possesses a number of contrasts common among Mixtec languages, such as voiceless unaspirated stops, prenasalized stops, and a strong tendency for words to conform to a minimally bimoraic structure. Using a controlled set of data, we focus on how word size and word position influence the acoustic properties of different consonant types. We examine closure duration, VOT, and formant transitions with the stop series, spectral moments with the fricative series, the timing between oral and nasal closure with the prenasalized stop series, and both formant transitions and qualitative variability with the glide series. The general effect of word size is discussed in relation to work on polysyllabic shortening (Turk & Shattuck-Hufnagel 2000) and demonstrates the importance of prosodic templates in Mixtec languages (Macken & Salmons 1997). The prenasalized stop data provides evidence that such stops are best analyzed as allophones of nasal consonants preceding oral vowels (as per Marlett 1992) and not as hypervoiced variants of voiced stops (as per Iverson & Salmons 1996).

Yoloxóchitl Mixtec 辅音的语音结构

尽管 Mixtec 语言以其声调系统而闻名，但关注辅音清单的工作相对较少。本文对 Yoloxóchitl Mixtec 语言（Oto-Manguean，ISO 639-3 代码）的辅音系统进行了深入的语音描述xty)，格雷罗米斯特克品种。该语言在 Mixtec 语言中具有许多常见的对比，例如清不送气塞音、前鼻塞塞音以及单词符合最小双莫拉结构的强烈趋势。使用一组受控数据，我们专注于如何字长和词位影响不同辅音类型的声学特性。我们用塞音系列检查闭合持续时间、VOT 和共振峰转换，用擦音系列检查谱矩，用鼻前塞音系列检查口鼻闭合之间的时间，以及用滑音系列检查共振峰转换和定性变异。一般效果字长讨论有关工作多音节缩短(Turk & Shattuck-Hufnagel 2000) 并展示了韵律模板在 Mixtec 语言中的重要性 (Macken & Salmons 1997)。鼻前化塞音数据提供的证据表明，最好将此类塞音分析为口元音之前的鼻辅音的同位异位音（根据 Marlett 1992），而不是作为浊塞塞音的高声变体（根据 Iverson & Salmons 1996）。
