AI Studio · audiobooks and podcasts
Turn your book into an AI audiobook or podcast
Upload the book, pick a narrator, voice and tone, and AI Studio reads it chapter by chapter, with a different voice for each character. You get an M4B with chapters and an MP3 per chapter, or a one- or two-host podcast with a script you can edit.
In short
UTIO's AI Studio turns a book (EPUB, DOCX, PDF or TXT) into an audiobook narrated chapter by chapter, or into a podcast. You pay as you go: €0.20 per minute of delivered audio, from your balance, with no monthly fee.
- It narrates in 15 languages, with several accents per language. Pre-recorded voice samples are available in Spanish, English and French.
- The voice is synthetic: no voice cloning and no human voice, and the opening credits say so. Every podcast ends with a synthetic-voices notice.
- You need the AI module (AI API / AI Studio), which we switch on in your account. It isn't part of the 14-day trial.
- A 5-hour book comes to about €60. You see the cost before generating, and takes redone by quality control aren't charged.
What AI Studio does
What's already in production, from uploaded book to downloads.
-
Audiobook by chapter
Upload the book as EPUB, DOCX, PDF or TXT (up to 12 MB) and it's split into chapters. Tick the ones to narrate and choose language, accent, narrator (male or female), voice and tone.
-
A voice for each character
Dialogue is detected and every character gets their own voice, with a child's voice for children. The text of the book is never changed.
-
Listen before you pay
Listening to the voices is free. You can also generate a sample of about 20 seconds from your own book, which costs cents.
-
Quality control, take by take
Every take is transcribed and checked. If it fails it's redone, and anything still off is delivered flagged "to review". You can also redo a whole chapter.
-
Review passage by passage
Fix the text, change who's speaking or ask for another take: only what you touch is regenerated and charged. Pronunciation dictionary included.
-
Downloads ready to publish
An M4B with chapters (Apple Books and most players) and a ZIP with one MP3 per chapter, mastered to audiobook platform standards.
-
A podcast from a chapter
One or two hosts with a name, voice and personality, and four formats: conversation, summary, Q&A or hands-on lesson. From 2 to 20 minutes. Edit the script turn by turn, then the audio comes out as MP3.
-
Book page and agent
A page for the book with blurb, cover, photos and a buy button, for anyone with the link. And an agent that answers only from what the book says, citing the chapter.
How to get started
The actual steps in the UTIO panel.
- Ask us to switch on the AI module (AI API / AI Studio) in your account.
- In the panel, go to AI agents → AI Studio → Audiobooks.
- Upload the book with its title and author, tick the rights box (you can't upload without it) and click "Upload and prepare".
- On the Audiobook tab, check chapters, voice and pronunciation, look at the cost in the bar and click "Generate audiobook". It runs in the background and lets you know at 25, 50 and 75% and when it's done.
- For a podcast, open the Podcast tab and click "New episode".
What it costs
€0.20/min
Per minute of delivered audiobook or podcast, from your balance. No monthly fee.
- Example: a 5-hour book (300 minutes) comes to about €60.
- Before starting, it checks there's enough balance for what's left. If the balance runs out halfway, it stops and keeps what's done.
- Takes redone by quality control aren't charged; when you review, you only pay for what you regenerate.
- Stand-alone voice generation (texts up to 5,000 characters): €0.05 per minute.
- Character detection costs one text request per chapter with dialogue. The book's agent, €0.015 per reply.
- Base rates, excluding VAT. If you buy through a partner, their rates apply.
What you need and what it doesn't do
So you know what to expect before uploading your first book.
What you need
- The AI module active in your account. We switch it on for you; it isn't part of the 14-day trial.
- Enough balance for what you're going to generate.
- The rights to the book: you have to declare them to upload it.
What it doesn't do
- No voice cloning and no human voice: the voice is synthetic and the opening credits say so.
- No distribution to Audible, Spotify or other stores: you get the downloads and a page of your own.
- It doesn't rewrite the book: character detection never changes the text.
- The book page doesn't show up in search engines: it isn't an SEO showcase.
- No automatic ad spots: you ask support for them.
- It isn't instant: generation runs in the background, and a chapter can take up to an hour.
- Outside Spanish, English and French, the "Listen to the voices" sample plays in Spanish and the podcast's closing notice comes out in English.
