Abstract

In this paper, we describe a method for modeling speech harmonic magnitudes, the accurate representation of which is essential for high quality speech synthesis in several parametric vocoders. The given set of harmonic magnitudes is interpolated and transformed into the auto-correlation domain before an all-pole model is derived. Through an iterative procedure, the interpolation curve used in the frequency domain is improved. This new iterative, interpolative, transform (IIT) method has been found to model the harmonic magnitudes more accurately than earlier methods when measured in terms of log-spectral distortion.
调和幅值建模的迭代插值变换方法
在本文中,我们描述了一种建模语音谐波幅值的方法,谐波幅值的准确表示对于在多个参数声码器中实现高质量的语音合成至关重要。在导出全极模型之前,将给定的谐波幅值组内插并变换到自相关域。通过迭代过程,改进了频域插值曲线。这种新的迭代,插值,变换(IIT)方法被发现比以前的方法更准确地模拟谐波幅度,当测量对数光谱失真时。
