KugelAudio’s Kugel is a multilingual TTS model with expressiveness control. It comes in two variants:
  • Kugel 1 Turbo: low-latency, optimized for real-time voice agents
  • Kugel 1: standard quality with full expressiveness control
You can control expressiveness with cfg_scale (0–10, default 2) and playback speed with speed (0.8–1.2). The same voice catalog is shared across both variants.
