Speech Self-Supervised Learning Using Diffusion Model Synthetic Data

ICML 2024oral

While self-supervised learning (SSL) in speech has greatly reduced the reliance of speech processing systems on annotated corpora, the success of SSL still hinges on the availability of a large-scale unannotated corpus, which is still often impractical for many low-resource languages or under privac…

Listen, Decipher and Sign: Toward Unsupervised Speech-to-Sign Language Recognition

ACL 2023findings

Existing supervised sign language recognition systems rely on an abundance of well-annotated data. Instead, an unsupervised speech-to-sign language recognition (SSR-U) system learns to translate between spoken and sign languages by observing only non-parallel speech and sign-language corpora. We pro…

ContentVec: An Improved Self-Supervised Speech Representation by Disentangling Speakers

ICML 2022spotlight

Self-supervised learning in speech involves training a speech representation network on a large-scale unannotated speech corpus, and then applying the learned representations to downstream tasks. Since the majority of the downstream tasks of SSL learning in speech largely focus on the content inform…
