PDF has no built-in structure, but SonikaAI finds chapter boundaries, strips out page noise, and delivers a navigable audiobook with cover art and metadata intact.
SonikaAI offers a voice preview page so you can hear every available voice before narrating your documents. Compare timbre, intonation, and naturalness with one consistent control phrase.
SonikaAI lets you set a page range before processing, so only the pages you need are translated or voiced. No need to split files or run entire documents.
