LACE: Layer-Wise Compression for Dynamic Frame Rate Codecs

Neural audio codecs are a key component in speech language modeling. However, their high frame rates lead to long sequence lengths, increasing computational costs. Dynamic frame rate codecs mitigate this by reducing the effective frame rate using a compression step to merge multiple frames together. However, most prior...

Speech Generation Speaker Poisoning: Capability Erasure in Zero-Shot Text-to-Speech

Speech Generation Speaker Poisoning (SGSP), a task that seeks to prevent a model from synthesizing targeted speaker identities while maintaining performance on all other speakers, is formulated and an evaluation framework based on AUC analysis and a proposed metric, Forget Set Similarity (FSSIM).
