Spark-TTS

Apache-2.0 code; CC-BY-NC-SA-4.0 weights

Built on Qwen2.5, zero-shot voice cloning + style control

Spark-TTS builds speech generation directly on a 0.5B Qwen backbone with a single-stream codec, making it unusually simple and efficient. It does zero-shot cloning plus controllable voice creation — set gender, pitch, and speaking style to synthesize a new voice from scratch.
