本文基于藤崎模型离散时间随机过程版本的表述，提出了一种语音基频（F0）轮廓的统计模型，藤崎模型被认为是代表声带振动控制机制的有根据的数学模型。这种统计公式有两个重要的动机。一是为 Fujisaki 模型导出通用参数估计框架，允许引入强大的统计方法，二是通过概率分布假设引入 F0 轮廓的语音自然度度量，该度量可以纳入许多统计语音处理问题，例如语音分析、合成、分离、去噪和去混响。
This paper proposes a statistical model of speech fundamental frequency (F0) contours, based on the formulation of the discrete-time stochastic process version of the Fujisaki model, which is known as a well-founded mathematical model representing the control mechanism of vocal fold vibration. There are two important motivations for this statistical formulation. One is to derive a general parameter estimation framework for the Fujisaki model, allowing for the introduction of powerful statistical methods, and the other is to introduce a measure of speech naturalness in terms of an F0 contour through a probability distribution assumption, that can be incorporated into many statistical speech processing problems such as speech analysis, synthesis, separation, denoising and dereverberation.
