Voice Morphing that improves TTS quality using an optimal dynamic frequency warping-and-weighting transform
ICASSP 2016accepted
Dynamic Frequency Warping (DFW) is widely used to align spectra of different speakers. It has long been argued that frequency warping captures inter-speaker differences but DFW practice always involves a tricky preprocessing part to remove spectral tilt. The DFW residual is successfully used in Voic…
