Deep Generative Factorization For Speech Signal(ICASSP21)

Introduction

• This paper presented a speech information factorization method based on a novel deep generative model that we called factorial discriminative normalization flow.

Qualitative and quantitative experimental results show that compared to all other models, the proposed factorial DNF can retain the class structure corresponding to multiple information factors, and changing one factor will cause little distortion on other factors. This demonstrates that factorial DNF can well factorize speech signal into different information factors.
