Nonparallel Emotional Voice Conversion for unseen speaker-emotion pairs using dual domain adversarial network Virtual Domain …

ICASSP, 2023
Nirmesh Shah*, Mayank Kumar Singh*, Naoya Takahashi, Naoyuki Onoe*

Primary goal of an emotional voice conversion (EVC) system is to convert the emotion of a given speech signal from one style to another style without modifying the linguistic content of the signal. Most of the state-of-the-art approaches convert emotions for seen speaker-emo…

DiffRoll: Diffusion-based Generative Music Transcription with Unsupervised Pretraining Capability

ICASSP, 2023
Kin Wai Cheuk*, Ryosuke Sawata*, Toshimitsu Uesaka*, Naoki Murata*, Naoya Takahashi, Shusuke Takahashi*, Dorien Herremans*, Yuki Mitsufuji*

In this paper we propose a novel generative approach, DiffRoll, to tackle automatic music transcription (AMT).Instead of treating AMT as a discriminative task in which the model is trained to convert spectrograms into piano rolls, we think of it as a conditional generative t…

Hierarchical Diffusion Models for Singing Voice Neural Vocoder

ICASSP, 2023
Naoya Takahashi, Mayank Kumar Singh*, Yuki Mitsufuji*

Recent progress in deep generative models has improved the quality of neural vocoders in speech domain. However, generating a high-quality singing voice remains challenging due to a wider variety of musical expressions in pitch, loudness, and pronunciations. In this work, we…
