本文介绍了一个通用和灵活的框架,用于F0和非周期性(加性非周期分量)分析,专门用于高质量的语音合成和修改应用。该框架由瞬时频率估计器和初始非周期性检测器、F0轨迹跟踪器和F0精化和非周期性提取三个子系统组成。所提出的框架的初步实现在跟踪随时间变化的F0轨迹方面显著优于现有的F0抽取器(按均方根F0估计误差为10倍)。前端非周期性检测器由一个具有高选择性时间包络和谱包络的复值小波分析滤波器组成。该前端非周期性检测器使用了一种新的测量方法来量化与周期性的偏差。该方法对慢调频和调幅较不敏感,并与信噪比密切相关。
This paper introduces a general and flexible framework for F0 and aperiodicity (additive non periodic component) analysis, specifically intended for high-quality speech synthesis and modification applications. The proposed framework consists of three subsystems: instantaneous frequency estimator and initial aperiodicity detector, F0 trajectory tracker, and F0 refinement and aperiodicity extractor. A preliminary implementation of the proposed framework substantially outperformed (by a factor of 10 in terms of RMS F0 estimation error) existing F0 extractors in tracking ability of temporally varying F0 trajectories. The front end aperiodicity detector consists of a complex-valued wavelet analysis filter with a highly selective temporal and spectral envelope. This front end aperiodicity detector uses a new measure that quantifies the deviation from periodicity. The measure is less sensitive to slow FM and AM and closely correlates with the signal to noise ratio.
