Ondoku | WordPress Text-to-Speech Plugin
Nov. 11, 2026
Hello
This article explains how to install and use the Ondoku WordPress plugin.
WordPress offers a wide variety of plugins.
Today, we’re introducing a text-to-speech plugin that converts articles you’ve written into audio and reads them aloud.
The plugin is easy to use!
Simply activate it after installation, then add a play button to the articles you want read aloud.
A player will appear on your blog page, allowing anyone to listen to the audio.
Now, let’s take a look at how to install and use the text-to-speech plugin.

Click “Add Plugin” to open the plugin installation screen.

Enter “Ondoku” in the search field.

The “Ondoku” plugin will appear. Install it.
*You can also download and manually install the plugin from the “Ondoku” plugin page on WordPress.org.
Once the plugin is installed, activate it.

3. Add your Ondoku access token to the plugin settings in WordPress
Once you activate the plugin, the settings screen will open automatically.

Set your access token to connect the plugin to Ondoku.
Click “Open settings page” to open the settings page.
Copy your access token from the settings page.

Return to your WordPress dashboard, paste in the access token, and save.

*Do not share your access token with others or publish it online.
Finally, choose your preferred read-aloud voice and save to complete the setup.

You can now use Ondoku to synthesize audio from the text of articles published on WordPress.
4. Publish an article and check that the read-aloud player is displayed
Once you’ve finished setting things up, check how it looks on an actual article.
When you publish a new article with the plugin activated, it will automatically be processed for read-aloud.
When you view the article, the player will appear at the top of your blog.

For previously published articles, the player will appear when you open the editing page and update the article.
You’ve now used the Ondoku WordPress plugin to turn a blog post into audio.
Things to Keep in Mind When Using the “Ondoku” Plugin
Available character limit and audio storage period for free users
Ondoku lets you convert up to 5,000 characters to speech for free each month.
For free users, audio is stored on Ondoku’s servers for 30 days.
After 30 days, it will be deleted and can no longer be played.
However, if you subscribe to a paid plan, your audio will be stored for the duration of your subscription until you delete it (learn more about plans here).
*If you cancel your subscription, your account will become a free account and the storage period will be 30 days, regardless of when the audio was created.
If you use Ondoku with a free account and want to keep audio on your blog for a long time, we also recommend downloading the MP3 and embedding it in your blog.
What to do if you run out of available characters while using the plugin
If you run out of available characters while using the plugin, the player will display an error recording that says “You have exceeded the available character limit.” instead of reading your blog content aloud.
Please keep the character limit in mind when using the plugin.
Why not try Ondoku’s WordPress text-to-speech plugin?
Audio content, including podcasts, has become increasingly popular lately.
Of course, there’s also demand for blog content that people can listen to rather than read.
Adding a player that reads your blog posts aloud can help you attract new fans!
Give Ondoku, the text-to-speech plugin, a try.
