GROUP RELATIVE POLICY OPTIMIZATION FOR TEXT-TO-SPEECH WITH LARGE LANGUAGE MODELS

This paper proposes a GRPO-based approach to enhance the performance of large language model (LLM)-based text-to-speech (TTS) models by deriving rewards from an off-the-shelf automatic speech recognition (ASR) model. Compared to previous reinforcement learning methods for LLM-based TTS, our method r…
