Performance Breakthroughs in Real-Time Speech Synthesis
For interactive application scenarios, CosyVoice innovatively proposes a streaming synthesis architecture based on Chunk-Streaming, which realizes 150ms first-packet latency through three core technologies:
- Dynamic chunking: Incremental generation of 20-ms speech frames
- Memory Optimization: Sliding Window Management for KV-Cache
- hardware acceleration: TensorRT-LLM inference engine integration
Tests under NVIDIA T4 hardware environment show that when processing mixed Chinese and English text, streaming mode saves 68% memory occupation than traditional non-streaming scheme, while ensuring rhyme continuity. In actual deployment, the technology has supported millions of intelligent outbound requests per day with an error rate of less than 0.3%. developers can enable this mode by setting the stream=True parameter.
