In their own words
AuthorVoices
AuthorVoices is a web platform for independent authors producing audiobook narration with curated AI voices. Authors can upload EPUB or DOCX files or paste text to start a project. Quick Fix re-narrates a selected passage without replacing the audio around it, and exports are available as MP3 and M4B. Users may create a private cloned voice from a recording after confirming it is their voice or that they have the owner’s written consent. The platform’s distribution channel reaches over 50 audiobook retailers, excluding Audible and Amazon; its terms also say Audible, ACX, and Amazon do not accept third-party AI-narrated audiobooks such as its output. Project-page distribution submission only accepts books built and exported within AuthorVoices. New accounts receive 5,000 narration characters and limited free voice-preview attempts. The service offers a free plan and trial. Paid choices include one-time book purchases and monthly studio plans, with listed plans from $49, paid once and $49 a month. Users retain manuscript ownership, and the terms say manuscripts are not used to train AI models.
