Run it yourself

How is a hosted job priced?

The server estimates credits from the normalized speech characters in your selected chapters. Full cast adds 50% before rounding at the default rate. Use the quote in Studio for your actual book.

What if a render fails?

Credits are reserved when a job starts, consumed on successful completion, and released on failure or cancellation.

Can everything run locally?

Speech synthesis runs locally after the initial downloads. A single narrator does not require a language-model provider. Full-cast quote attribution uses the provider you configure, which may be local or remote.

Can I edit and preview individual lines in Studio?

The Python library supports script inspection, corrections and selected-line previews. Those controls are not yet exposed by the Studio server API. The recordings on this site are examples, not previews of an uploaded book.
