Fine-grained Noise Control for Multispeaker Speech Synthesis
A text-to-speech (TTS) model typically factorizes speech attributes such as
content, speaker and prosody into disentangled representations.Recent works aim
to additionally model the acoustic conditions explicitly, in order to
disentangle the primary speech factors, i.e. linguistic content, prosody and
timbre from any residual factors, such as recording conditions and background
noise.This paper proposes unsupervised, interpretable and fine-grained noise
and prosody modeling. We incorporate adversarial training, representation
bottleneck and utterance-to-frame modeling in order to learn frame-level noise
representations. To the same end, we perform fine-grained prosody modeling via
a Fully Hierarchical Variational AutoEncoder (FVAE) which additionally results
in more expressive speech synthesis.Comment: Accepted to INTERSPEECH 202
