Spark-TTS

Spark-TTS is an LLM-based text-to-speech model using BiCodec, a single-stream speech codec that decouples speech into semantic tokens and speaker-specific global tokens, enabling zero-shot voice cloning and fine-grained control over linguistic content and speaker attributes via chain-of-thought generation with Qwen2.5.
