  title={FastPitchFormant: Source-filter based Decomposed Modeling for Speech Synthesis},
  author={Taejun Bak and Jaesung Bae and Hanbin Bae and Young-Ik Kim and Hoon-Young Cho},
Methods for modeling and controlling prosody with acoustic features have been proposed for neural text-to-speech (TTS) models. Prosodic speech can be generated by conditioning acoustic features. However, synthesized speech with a large pitch-shift scale suffers from audio quality degradation, and speaker characteristics deformation. To address this problem, we propose a feed-forward Transformer based TTS model that is designed based on the source-filter theory. This model, called…
