Query: Transforming Spectrum and Prosody for Emotional Voice Conversion with
  Non-Parallel Training Data   Emotional voice conversion aims to convert the spectrum and prosody to change
the emotional patterns of speech, while preserving the speaker identity and
linguistic content. Many studies require parallel speech data between different
emotional patterns, which is not practical in real life. Moreover, they often
model the conversion of fundamental frequency (F0) with a simple linear
transform. As F0 is a key aspect of intonation that is hierarchical in nature,
we believe that it is more adequate to model F0 in different temporal scales by
using wavelet transform. We propose a CycleGAN network to find an optimal
pseudo pair from non-parallel training data by learning forward and inverse
mappings simultaneously using adversarial and cycle-consistency losses. We also
study the use of continuous wavelet transform (CWT) to decompose F0 into ten
temporal scales, that describes speech prosody at different time resolution,
for effective F0 conversion. Experimental results show that our proposed
framework outperforms the baselines both in objective and subjective
evaluations.
