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.

Factor manipulation
- MLP posteriors on the target class before and after phone/speaker manipulation. ‘f-DNF’ denotes factorial DNF. δ(·) denotes the difference on posteriors p(·|x') and p(·|x)

Future Work
- Test factorial DNF on larger datasets.
- Establish general theories for deep generative factorization.
