Data-efficient Targeted Token-level Preference Optimization for LLM-based Text-to-Speech (2026.acl-short)
Copied to clipboard
| Challenge: | Recent work has shown that text-to-speech (TTS) models generate contextaware pronunciations from raw text without morphological analysis. |
| Approach: | They propose a preference optimization algorithm that aligns text-to-speech (TTS) outputs with human feedback. |
| Outcome: | The proposed method improves the challenging Japanese pronunciation accuracy by 39% and reduces CER by 54%. |
