本文提出了一种改进的倾斜模型，称为T-Tilt，用于分析和合成调性语言中的F0轮廓。将成功设计用于语调建模的Tilt模型扩展到受声调上下文强烈影响的基于音节的F0实现。两种修改方法包括添加指示F0曲线模式的参数和分离Tilt参数中固有的持续时间和幅度控制，以提高灵活性。通过客观RMSE测量和主观MOS测试在可理解性和自然性方面进行评估。通过对泰语和汉语普通话连续语音的分析，证明了该模型对连续语音的F0轮廓分析是非常有效的。它需要大量的参数综合工作，尽管综合性能与其他提出的模型产生的性能相当。
This paper proposes a modified Tilt model, called T-Tilt , for analyzing and synthesizing F0 contours in tonal languages. The Tilt model successfully designed for intonation modeling is extended to cover syllable-based F0 realization influenced strongly by the tonal context. Two modification approaches include adding a parameter indicating a F0 curve pattern and separating duration and amplitude controls inherent in the Tilt parameter for sake of flexibility. Evaluations are conducted by both an objective RMSE measure and a subjective MOS test on intelligibility and naturalness aspects. Applying to Thai and Mandarin Chinese continuous speech, the proposed model is proved to be very effective for F0 contour analysis. It rather requires extensive work on parameter synthesis although the synthesizing performance is comparable to those produced by other proposed models.
