Has anyone tried ChatterBoxTTS for production use? Voice quality concerns

I've been experimenting with ChatterBoxTTS for a customer-facing app and the zero-shot cloning is genuinely impressive, but I'm hitting some consistency issues with longer passages. The voice drifts slightly mid-sentence in about 20% of my test cases. Before I invest more time optimizing parameters, wanted to check if others have solved this or if it's just a limitation I need to work around. Anyone running this in production?
