Lewis Carroll
Alice's Adventures in Wonderland
Alice asks the grinning Cheshire Cat for directions — and gets none.
The Cat only grinned when it saw Alice. It looked good-natured, she thought; still it had very long claws and a great many teeth, so she felt it ought to be treated with respect.

In depth
Not every story lives in a finished book file. Short stories, serial chapters and works in progress usually sit in a notes app, a forum post or a draft. Text to audiobook is the shortcut for those: paste the words in and get audio out, without building an EPUB first.
FullCastBook does more than read the paste aloud. It splits narration from dialogue, works out who says each quoted line, and gives the narrator and every character their own voice. The demo above plays a full-cast scene; for a line or two of plain speech, the text-to-speech playground on the home page is quicker.
Paste the text, check the cast, export: that's the whole loop. The paste box takes anything from one scene to a full manuscript, and a TXT file works the same way if the text is already saved. Plain text is decoded whether it was saved as UTF-8, UTF-16 or an older Windows or Chinese encoding, so curly quotes and accented names survive.
If the text has chapter headings, keep each on its own line. "Chapter 1", "CHAPTER ONE", "Part Two", "Prologue" and "Epilogue" each start a new chapter, and a short line right after "Chapter 1" becomes its title. Without headings, a short paste stays one chapter and a long one is cut at paragraph breaks into parts of about 20,000 characters.
A TXT to audiobook conversion follows the same rules as the paste box. One chapter can hold up to 200,000 characters, so if a single chapter runs longer, add a heading inside it to split it. A project holds up to 3 million characters, which is several long novels.
Anything before the first heading, such as a title page or copyright notice, becomes an "Opening" section you can leave out, and headings with no text under them, like the lines of a contents list, are dropped rather than turned into empty chapters.
Plain text to speech reads everything in one voice. That's fine for an article, but fiction is a conversation: with three people talking, one voice makes the listener track every "she said" to know who has the line. A text to speech audiobook built as a cast fixes that. The narrator keeps the prose, and each character's lines are read in their own voice.
Detection does most of the casting, but it's a first pass. Unattributed back-and-forth or two characters with similar names can be read the wrong way, so skim the dialogue and move any line to the right speaker before you generate. For more on casting, see multiple voices text to speech.
Story to audio is what most people use the paste box for. A short story becomes one MP3 you can share. A web serial becomes a project you add to chapter by chapter, with the same cast each week. A draft becomes something you can listen to on a walk, where clunky dialogue and missing tags tend to jump out.
If the text already lives in a Word file, upload that instead: Word document to audiobook uses your heading styles as chapters.
Because you're working from plain text, direction goes straight into it. Write a note in brackets before a line, like [whisper, like sharing a secret] or [tired, barely awake], and the delivery follows. Sound tags such as [laugh], [sigh] and [breathe] add the small noises that make a scene feel real.
Use them at the turning points, not everywhere. If a line still lands wrong, edit it or move the note and regenerate only that line. Regenerating uses credits again, so a light touch keeps the cost down.
When it sounds right, download one MP3, an M4B with chapter markers for audiobook players, or a ZIP with a file per chapter. The audio is yours, with no DRM added. For everything the studio does, see the AI audiobook generator, and check pricing for plans.
You get free credits on sign-up, with no card, which is enough for a short sample chapter with a full cast. Longer texts need a paid plan; see pricing.
A whole manuscript, if you like. One chapter can hold up to 200,000 characters and a project up to 3 million, so long texts just need chapter headings to split them.
Yes. Upload the TXT file, check the chapters and the cast, and export one MP3, a ZIP with one file per chapter, or an M4B with chapter markers.
Yes. Every speaking character is detected and given a distinct voice next to the narrator, and you can swap any voice or move any line to another speaker.
