Tips & Tricks

For **Audiobooks**, use **MP3** format, enable **Split text**, and set a chunk size of ~250-500.
Use **Predefined Voices** for consistent, high-quality output. You can import new ones.
For **Voice Cloning**, upload clean reference audio (.wav/.mp3). Quality of reference is key.
Experiment with **Temperature** and other generation parameters to fine-tune output.
Adjusting **Speed Factor** away from 1.0 is experimental and may cause echo.
Check the /docs endpoint for API details.
