Towards Codec-LM Co-design for Neural Codec Language Models (2025.naacl-srw)
Copied to clipboard
| Challenge: | Neural codec language models (or codec LMs) are emerging as a powerful framework for text-to-speech (TTS) despite the close interdependence of codecs and LM, research on codec and lms has largely remained siloed. |
| Approach: | They propose a frame-wise codec encoder that improves both LM log-likelihood and TTS metrics . they also propose LM codebook level dropout to efficiently navigate a portion of codec-LM design space . |
| Outcome: | The proposed codec-LM co-design improves intelligibility, audio quality and speaker control compared to a siloed baseline. |
