This is what multi-voice narration sounds like. Each character gets their own voice.

The door opened and Thomas stepped in, still wearing his coat from the walk. He set a paper bag on the side table and looked at her face.

"What's happened?" he asked, pulling a chair closer. "You look like someone's cancelled Christmas."

Margaret set the letter down and pressed her fingertips together. "The university is closing the department. The whole thing. Effective end of term."

"They can't do that. You've been there fifteen years."

"Apparently the provost disagrees."
The problem

AI narration tools give you audio.
They don't give you an audiobook.

You can generate a voice track in minutes. But between that track and a published audiobook, there are a dozen ways it goes wrong.

✗

Skipped sentences

The AI dropped a paragraph in chapter 14. You didn't catch it. Your reader did — in a one-star review. Other tools don't check whether the narration actually matches your manuscript.

✗

Rejected by the platform

Findaway rejected your files because the RMS levels were -16 dB. Or the noise floor was too high. Or there wasn't enough head silence. You don't know what any of that means, and now you're Googling ffmpeg at midnight.

✗

Names mispronounced

Your protagonist is named "Siobhan" and the AI said "See-oh-ban" for nine hours straight. Other tools have no pronunciation dictionary. You'd have to regenerate the entire book — and pay again.

✗

Every character sounds the same

The hero, the villain, and the love interest all speak in the same voice. No casting. No differentiation. Your listeners can't tell who's talking — and they stop listening.

What Narrato does differently

Every problem above, solved
before you hit publish.

✎

Proof every word against your manuscript

After narration, Narrato transcribes the audio and diffs it word-by-word against your original text. Skipped sentences, repeated lines, wrong words, pacing anomalies — every issue is flagged with a clickable timestamp so you can hear exactly where it went wrong and fix just that section.

♫

Master and certify for your platform

Choose your distribution platform — Findaway, Google Play, Apple Books, Kobo — and Narrato automatically normalizes every chapter to that platform's exact spec: RMS levels, peak limits, noise floor, silence padding, sample rate, encoding. No ffmpeg. No guesswork. No rejection emails.

✔

A score that proves it's ready

Every audiobook gets a Narrato Score from 0 to 100 — a single number combining technical compliance, proofing accuracy, and platform readiness. Download the per-chapter compliance report. If a platform ever questions your submission, you have the documentation.

♪

Cast unique voices for each character

Narrato reads your manuscript and identifies every speaking character — name, personality, line count. Assign each one a distinct voice. Preview them reading their actual dialogue. Generate with automatic voice switching between narrator and characters. Or choose a single narrator who voices everyone through tone — your call.

📚

Pronunciation you control

Add pronunciation rules before generation — "Siobhan" becomes "shuh-VAWN," "Hermione" becomes "her-MY-oh-nee." Narrato also auto-detects tricky names and foreign words and suggests phonetic guides. Fix it once, correct everywhere.
