How to turn blog posts into audio

Turn a written post into narrated audio with an AI voice, then embed the player on your site with one script tag.

How do you turn blog posts into audio?

ButterReader turns a blog post into audio by reading the article text on the page and narrating it with an AI voice, inside a player you embed with one line of code. You do not record, edit or host audio files yourself.

What are the steps?

ButterReader's setup has three steps:

  1. Create a player at app.butterreader.blog. Pick a voice and style the player to match your site.
  2. Copy the embed snippet and paste it into your post, or into your blog template so every post gets it.
  3. Publish. When someone opens the page, the widget detects the article text, skips navigation, sidebars and comments, and generates the narration.

The same player can sit on every post. It narrates whichever page it is on, so one snippet covers your archive.

Which voices can I use?

ButterReader uses Google's Chirp 3 HD voices for natural narration on every plan. Pro plans add Gemini Flash voices for more expressive delivery, which count as 2 credits per character against the monthly cap. The voices are English (US). Natural vs. expressive, compared.

How long can a post be?

ButterReader narrates the whole article up to 60,000 characters, generating long posts in chunks automatically. Your monthly character cap is 10,000 on the free plan and 100,000 on Monthly or Yearly Pro (pricing).

What makes the audio sound right?

ButterReader reads what is on the page, so the writing decides the result:

  • Keep body copy in real paragraph and heading tags. Text inside bare div or span elements can be skipped.
  • Make sure the full text is present when the page loads, not hidden in tabs.
  • Listen to the first thirty seconds before publishing. Proper nouns, acronyms and words with two pronunciations are where synthetic voices slip.

If the player reads the wrong section, set a content selector for your article container in the player settings.

Can I see if people listen?

Yes. ButterReader's player tracks plays, listening time and completion, so you can tell which posts people actually listen to.

Can I use audio I already recorded?

Yes. ButterReader also has upload players that wrap an existing audio file, such as a voice recording or a music track, in the same styled player. Adding a music player.
