基于F0自适应基音同步谱估计和选择性消除周期性干扰的弹性谱距离测度是为高质量语音修改过程STRAIGHT [1]而开发的，它为听觉变形提供了基础。所提出的措施是在目标和原始语音表示之间的低维分段双线性时频映射上实现的。变形情感语音样本的初步测试结果表明，该方法提供了感知单调和高质量的CD质量的语音样本的内插和外推。
An elastic spectral distance measure based on a F0 adaptive pitch synchronous spectral estimation and selective elimination of periodicity interferences, that was developed for a high-quality speech modification procedure STRAIGHT [1], is introduced to provide a basis for auditory morphing. The proposed measure is implemented on a low dimensional piecewise bilinear time-frequency mapping between the target and the original speech representations. A preliminary test results of morphing emotional speech samples indicated that proposed procedure provides perceptually monotonic and high-quality interpolation and extrapolation of CD quality speech samples.
