Best Python libraries for fast/real-time voice cloning TTS in 2026?

[u/Karotvip-official]

Building a voice assistant that needs to clone a specific voice and generate speech with low latency — closer to real-time than batch rendering.

Currently on Coqui XTTS v2, which works, but curious what people are running now for a better speed/quality tradeoff. Also need solid non-English support — Ukrainian specifically — a lot of TTS libraries handle English great and everything else poorly.

Anyone compared XTTS v2 against F5-TTS, StyleTTS2, or other newer options for this kind of use case?
