When annotating a speech signal using an autosegmental-metrical model of intonation, transcribers associate portions of the F 0 contour with labels from a finite inventory of tonal categories. In the models we are concerned with here, these categories have the status of phonological units (phonological form), bridging the intrinsic variability of the speech signal (substance) with the intrinsic fuzziness of post-lexical function (meaning). This, together with the relatively small size of the label inventory, precludes a one-to-one relationship between form and substance, and/or between form and function. A Neapolitan Italian corpus of read speech is used to investigate the distributional properties of two pitch accents that have been studied extensively with respect to substance (the alignment of F 0 peaks) and meaning (sentence modality). Although there is a general consensus that peaks in this variety are aligned earlier in declaratives than in interrogatives, evidence is provided of contexts in which the converse is true, i.e., in which interrogative peaks are even earlier than their declarative counterparts. In this respect, interrogatives have a richer internal structure than declaratives. We argue that differences in how variably a prosodic category is encoded can be dealt with in an intonation transcription system, as long as this system relates phonological form (the choice of pitch accent in this case) both to phonetic substance and to meaning in a transparent way.

在语调的自动分段度量帐户中对类别进行分布方法的重要性

当使用语调的自动分段度量模型注释语音信号时，转录员将 F 0 轮廓的部分与有限的音调类别清单中的标签相关联。在我们在这里关注的模型中，这些类别具有语音单位（语音形式）的状态，将语音信号（物质）的内在可变性与后词汇功能（含义）的内在模糊性联系起来。这与标签库存相对较小的尺寸一起，排除了形式与物质之间和/或形式与功能之间的一对一关系。使用那不勒斯意大利语语料库来研究已在实质（F 0 峰的对齐）和意义（句型）方面广泛研究的两种音高重音的分布特性。尽管普遍认为该变体中的峰值在陈述句中比在疑问句中更早对齐，但提供了相反的上下文的证据，即疑问句的峰值甚至比其陈述句更早。在这方面，疑问句比陈述句具有更丰富的内部结构。我们认为，可以在语调转录系统中处理韵律类别编码方式的差异，只要该系统将语音形式（在这种情况下，音调重音的选择）与语音内容和透明的含义联系起来。办法。其中疑问峰甚至比陈述句更早。在这方面，疑问句比陈述句具有更丰富的内部结构。我们认为，可以在语调转录系统中处理韵律类别编码方式的差异，只要该系统将语音形式（在这种情况下，音调重音的选择）与语音内容和透明的含义联系起来。办法。其中疑问峰甚至比陈述句更早。在这方面，疑问句比陈述句具有更丰富的内部结构。我们认为，可以在语调转录系统中处理韵律类别编码方式的差异，只要该系统将语音形式（在这种情况下，音调重音的选择）与语音内容和透明的含义联系起来。办法。
