New method decodes hidden lexical variance in speech embeddings

Researchers have developed a new method called Asymmetric Correspondence Learning (ACL) to better understand the information encoded within speech embeddings. ACL aims to distill HuBERT features into separate Acoustic Word Embeddings (AWEs) and Acoustic Style Embeddings (ASEs). While AWEs effectively cluster lexical information, ASEs retain significant, yet linearly unrecoverable, lexical variance alongside speaker information, suggesting current benchmarks may not fully capture the complexity of these latent spaces.
