Generation and Normalization of Tonal Variations
声调变化的生成与正规化
Chilin Shih 石基琳

Abstract 摘要
Tone shapes in connected speech can be drastically different from their canonical citation forms. The variations are conditioned by many different factors, some have local effects and some have global effects. This paper identifies the sources of some effects, examining the scope and magnitude of these effects with experimental data, and exploring how the results can be modeled for both f0 generation and data normalization.

连续语句中的声调形态，往往与单字调有相当的出入。这些变化有一定的肇因。有的因素会造成局部的影响。有的因素则有长期的效应。要确切掌握这些因素，做成功的数据仿真并不容易。不过，我们可以利用中文声调的特性，解决一部分的问题。本文讨论两个实验，研究一些因素对声调影响的范畴与幅度，藉以探讨如何处理声调调型的生成及正规化。
