Researchers have developed a novel reinforcement learning technique, RLVR, to improve the data efficiency of audio-language models for code-switched Automatic Speech Recognition (ASR). This method utilizes group relative policy optimization with a combination of error rate and script fidelity rewards to adapt models like Qwen2-Audio. Experiments show that RLVR, trained on only 10% of the data, can match the performance of supervised fine-tuning using the full dataset, particularly excelling with typologically distant language pairs and transferring gains to human-recorded speech.
