Sopro V2 Turbo: 120M voice-cloning TTS, 5x faster than real time on a CPU
Open-sourced Sopro V2 Turbo crams voice cloning into 120M parameters: it clones a voice from 5 to 20 seconds of reference audio and hits ~300 ms to first audio on a laptop CPU. That's 5x faster than real time on an M3 (0.07 RTF on an H100), streaming full sentences in English, European Portuguese, French, and German. A one-command local web UI and a fully in-browser ONNX demo ship with the repo.
