FullCastBook
AI audiobook maker with a full cast: every character gets its own voice, then export M4B with chapters or MP3
FullCastBook turns a manuscript into an AI audiobook with a full cast. Upload an EPUB, PDF, DOCX, TXT or Markdown file, or paste a chapter, and it finds the chapters, works out who is speaking in each line and gives every character a distinct voice alongside an AI narrator. Swap any voice from a library of standard and premium voices, and keep the same cast across a series.
Direct any line in plain English by adding a note in brackets, such as [whisper, like sharing a secret], and drop sound tags like [laugh], [sigh] or [breathe] exactly where they belong. Regenerate a single line without redoing the chapter, then export the finished audiobook as one M4B with chapter markers, MP3 files or a ZIP.
Signing up is free with no card; audio is paid with credits from a plan (from $9.90 a month). English works best today.
