Query: Improving multi-speaker TTS prosody variance with a residual encoder and
  normalizing flows   Text-to-speech systems recently achieved almost indistinguishable quality
from human speech. However, the prosody of those systems is generally flatter
than natural speech, producing samples with low expressiveness. Disentanglement
of speaker id and prosody is crucial in text-to-speech systems to improve on
naturalness and produce more variable syntheses. This paper proposes a new
neural text-to-speech model that approaches the disentanglement problem by
conditioning a Tacotron2-like architecture on flow-normalized speaker
embeddings, and by substituting the reference encoder with a new learned latent
distribution responsible for modeling the intra-sentence variability due to the
prosody. By removing the reference encoder dependency, the speaker-leakage
problem typically happening in this kind of systems disappears, producing more
distinctive syntheses at inference time. The new model achieves significantly
higher prosody variance than the baseline in a set of quantitative prosody
features, as well as higher speaker distinctiveness, without decreasing the
speaker intelligibility. Finally, we observe that the normalized speaker
embeddings enable much richer speaker interpolations, substantially improving
the distinctiveness of the new interpolated speakers.
