When you post an article with the plugin activated, text-to-speech is automatically processed internally, and a player is displayed at the beginning of the blog post.

For past articles, the player will appear when you edit and then publish them.

Precautions when using the "Ondoku" plugin

Ondoku can read up to 5,000 characters per month for free.

Also, for free use, the audio storage period on Ondoku's server is 30 days.

After 30 days, it will be deleted and you will not be able to listen to it.

However, if you subscribe to a paid plan (from 200,000 characters / 980 yen per month), the audio will be stored until the user deletes it during the subscription period.

※If you cancel, you will become a free member, and the storage period will be 30 days regardless of when it was created.

Therefore, if you intend to use it as a free member of Ondoku and use it for a long period, we recommend downloading and then embedding it instead of using the plugin.

If you run out of available characters while using the plugin, an error message "Available characters exceeded." will be displayed as an audio player instead of the blog's content.

Please be careful about the character limit when using it.

Recently, listening content has become more popular.

There is also a demand for listening to blogs with the ears rather than reading them with the eyes.

Adding a player that reads aloud the content of your articles to your blog might lead to gaining new fans!

Please try the text-to-speech plugin, Ondoku.
