Fully Unsupervised Training of Few-shot Keyword Spotting

no code implementations6 Oct 2022 Dongjune Lee, Minchan Kim, Sung Hwan Mun, Min Hyun Han, Nam Soo Kim

For training a few-shot keyword spotting (FS-KWS) model, a large labeled dataset containing massive target keywords has known to be essential to generalize to arbitrary target keywords with only a few enrollment samples.

Disentangled Speaker Representation Learning via Mutual Information Minimization

no code implementations17 Aug 2022 Sung Hwan Mun, Min Hyun Han, Minchan Kim, Dongjune Lee, Nam Soo Kim

The experimental results show that fine-tuning with a disentanglement framework on a existing pre-trained model is valid and can further improve performance.

Bootstrap Equilibrium and Probabilistic Speaker Representation Learning for Self-supervised Speaker Verification

no code implementations16 Dec 2021 Sung Hwan Mun, Min Hyun Han, Dongjune Lee, JiHwan Kim, Nam Soo Kim

In this paper, we propose self-supervised speaker representation learning strategies, which comprise of a bootstrap equilibrium speaker representation learning in the front-end and an uncertainty-aware probabilistic speaker embedding training in the back-end.
