General limitations of the free version

Common problems and solutions

"Ondoku" has a feature that lets you specify how to read kanji, allowing you to achieve accurate pronunciation!

Technical terms and proper nouns are particularly prone to misinterpretation, so we recommend checking them in advance.

Voice Quality Issues

If the voice quality is poor, consider switching to a service that uses a higher quality AI engine.

Services like "Ondoku" use the latest AI technology to enable more natural speaking .

With installed software, audio quality may be poor if your computer has low specifications.

In that case, we recommend using a browser-based service that processes data in the cloud and does not require installation .

Installation and access issues

If you cannot install downloadable software, check the settings of your security software.

It is also important to check the system requirements as your OS may not be compatible.

If you can't access a browser-based service that requires no installation, one solution is to try changing your browser.
