论文摘要
最近显示，通过分离语音的因果和抗苏族成分，可以有效地使用复杂的圆锥体进行震颤流动估计。为了保证正确的估计，窗口上的一些约束已得出。其中，窗口必须在闭合瞬间同步。本文提出了通过纳入CHIRP分析来扩展基于Cepstrum的分解。结果显示，所得的方法可以在窗口所在的任何地方对glottal流进行可靠的估计。然后，该技术适合将其集成到通常的语音处理系统中，该系统通常以异步方式运行。除了强调了自动语音质量分析的潜力外。
It was recently shown that complex cepstrum can be effectively used for glottal flow estimation by separating the causal and anticausal components of speech. In order to guarantee a correct estimation, some constraints on the window have been derived. Among these, the window has to be synchronized on a Glottal Closure Instant. This paper proposes an extension of the complex cepstrum-based decomposition by incorporating a chirp analysis. The resulting method is shown to give a reliable estimation of the glottal flow wherever the window is located. This technique is then suited for its integration in usual speech processing systems, which generally operate in an asynchronous way. Besides its potential for automatic voice quality analysis is highlighted.
