Query: Non-parallel Emotion Conversion using a Deep-Generative Hybrid Network
  and an Adversarial Pair Discriminator   We introduce a novel method for emotion conversion in speech that does not
require parallel training data. Our approach loosely relies on a cycle-GAN
schema to minimize the reconstruction error from converting back and forth
between emotion pairs. However, unlike the conventional cycle-GAN, our
discriminator classifies whether a pair of input real and generated samples
corresponds to the desired emotion conversion (e.g., A to B) or to its inverse
(B to A). We will show that this setup, which we refer to as a variational
cycle-GAN (VC-GAN), is equivalent to minimizing the empirical KL divergence
between the source features and their cyclic counterpart. In addition, our
generator combines a trainable deep network with a fixed generative block to
implement a smooth and invertible transformation on the input features, in our
case, the fundamental frequency (F0) contour. This hybrid architecture
regularizes our adversarial training procedure. We use crowd sourcing to
evaluate both the emotional saliency and the quality of synthesized speech.
Finally, we show that our model generalizes to new speakers by modifying speech
produced by Wavenet.
