Make it more convenient with the text-to-speech software 【Ondoku】 Google Chrome extension! How to set up and use

Hello, thank you for always using Ondoku.

There is a feature especially recommended for those who use Ondoku with Google Chrome.

That is the Google Chrome extension.

By installing the Ondoku extension in Google Chrome, you can read out specific sections on the spot using the Ondoku extension.

You will no longer have to go through the double effort of copying text, going to the Ondoku site, and pasting it to read it aloud!

If you use the Google Chrome browser as your main browser, it is an extension worth installing!

Now, let's explain how to add the extension to Google Chrome.

Open "Ondoku" in the Chrome Web Store

How to read text with the Ondoku extension

How to read with Ondoku extension

Reading text with the Ondoku extension is easy!

  • Select a range within the web page and click the icon or press the shortcut key to read it aloud.

That's all you need to do.

Precautions for text reading with the extension

When reading text with the extension, if you click elsewhere before the loading is complete, the loading will disappear.

Please be careful not to click anywhere while loading.

Once loading is finished, the audio will be read aloud, and clicking elsewhere will not interrupt the reading.

Operation via shortcut keys is also possible!

Reading audio is very simple as it can be done by clicking the icon or using shortcut keys.

For those who find it troublesome to click the pink headphone logo button, shortcut keys are highly recommended.

The default shortcut key is "command + shift + o".

However, this applies only if this shortcut key does not conflict with others on the computer you are using.

If you are using the same shortcut key for another command, please set a different shortcut key.

You can change the shortcut key here (clicking will open the Google Chrome feature settings screen).
