LLM -Codec: Neural Audio Codec Meets Language Model Objectives
Ho-Lam Chung · Yiming Chen · Hung-yi Lee
摘要
Neural audio codecs are widely used as tokenizers for spoken language models, but they are optimized for waveform reconstruction rather than autoregressive prediction.This mismatch injects acoustically driven uncertainty into the discrete token space and increases language-model perplexity.We pro...
