Researchers have developed Faster IndexTTS-2, a method to significantly accelerate the IndexTTS-2 text-to-speech model for GPU deployment. This new version optimizes the autoregressive GPT and Diffusion Transformer components, achieving up to a 5.0x speedup for the GPT and 3.6x end-to-end. Faster IndexTTS-2 also introduces streaming synthesis capabilities for interactive applications and batch inference to maximize GPU utilization, with minimal impact on synthesis quality. AI
