For newsletters and publishers

Every article, listenable, by the time it publishes.

Readers increasingly press play instead of scrolling. Turn a finished article into a narrated edition in minutes: one narrator voice held across every story, drafted on the fastest engine, exported as a file you embed wherever the writing lives.

The moment

Your newsletter goes out at six a.m. and your readers open it on the train, where reading loses to listening. The big publications ship a narrated edition of every story; you are one person with a deadline. The article is finished. Making it listenable should take minutes, not a studio.

Why this is hard

What Articles to Audio actually needs.

We would rather name the friction plainly than pretend it away. Here is the problem this page is about.
The honest problem

Publishing moves at a daily cadence, and recording a human read of every article cannot keep up. The narrated editions readers now expect either do not exist for smaller publications or arrive days late, after the story has gone cold. What a publisher needs is a read that is ready when the article is: generated in minutes, in the same narrator voice every edition, without a per-article production budget.

How Cantari helps

Real features, mapped to the job.

Every item here works today, or says plainly where it is still in progress.

Narrate at publishing cadence

Kokoro drafts fastest of the engines here, so the audio edition is ready minutes after the article is, not days.

One narrator across editions

Lock a single voice so Tuesday's brief sounds like Monday's. Readers learn the voice the way they learn a masthead.

A full feature in one pass

Up to 30,000 characters per generation, so even a long-read goes through whole instead of stitched from fragments.

Own and embed the audio

Export MP3 or WAV with commercial rights and no watermark, yours to embed in the newsletter, the CMS, or a private feed.

Worked example

Narrated article: this morning's lede

Script fragmentKokoro

Good morning. This is the audio edition of The Crosstown Memo for Tuesday, June tenth.

The city council voted seven to two last night to extend the waterfront lease, ending a fight that has run since March.

Here is what the vote means, in the time it takes you to finish your coffee.

The workflow

How it goes, step by step.

Step 1: Paste the finished article

Drop the published text into Text to Speech. Strip captions and pull-quotes so the read flows.

Step 2: Keep your narrator

Pick one Kokoro voice and use it for every edition, so the audio brand stays consistent.

Step 3: Generate and check the lede

Generate, listen to the opening paragraph, and regenerate if a name or number reads wrong.

Step 4: Embed where the writing lives

Export the MP3 and place it at the top of the article or newsletter. It is yours to host anywhere.

Distribution notes

Where AI audiobook narration can actually go today.

Indie publishers keep asking where a generated audiobook can be sold, and most answers online are wishful. Here is the honest map, checked against each platform's own pages.

ACX and Audible: not through the front door

ACX, the pipeline most publishers use to reach Audible, requires human narration: its submission rules prohibit text to speech, AI, or automated recordings unless ACX itself authorizes them. A title narrated here cannot be submitted through ACX today, and we would rather print that than let you find out after producing the book.

Amazon's Virtual Voice is its own lane

Amazon KDP's virtual voice beta narrates eligible KDP eBooks with Amazon's own synthetic voices and sells the result alongside Audible titles. It is real, and it is closed: a publisher cannot upload externally produced AI narration through it. It tells you where Amazon is heading, not where your file can go.

Spotify takes digital voice narration, disclosed

Spotify accepts audiobooks with digital voice narration and adds a disclosure line to the book's description so listeners know what they are buying. For a small publisher this is the open door today: produce the narration, own the master, and ship it with the label it deserves.

All three platform pages were checked live on June 11, 2026. Distribution policy shifts quarter to quarter; reread the links before committing a catalog.

The honest answers.

What Cantari can and cannot do for articles to audio today, in plain language.

Can this run automatically when I publish?
Not yet. There is no public API today, so the honest workflow is paste, generate, export, which takes a few minutes per article in the console. The API tab in the console is labeled soon, and that label means what it says.
Will the voice stay the same across hundreds of articles?
Yes. Engines read from fixed voices, so the same voice on the same engine sounds consistent edition after edition. That consistency is the point for a publication.
Can I put the audio behind my own paywall?
Yes. Every generation is yours to export and host commercially, with no watermark and no attribution required, on your site, your feed, or your subscriber-only space.
