In particular, AI text-to-speech technology has evolved rapidly recently, making it possible to generate high-quality audio even with free services.

As of 2026, AI text-to-speech is utilized in many situations, including video narration production, improving website accessibility, and converting e-books into audio.

Text-to-speech sites include types that can be used directly from a browser and types that are downloaded and installed on a computer.

Browser-based services that do not require installation can be easily used from smartphones and tablets, allowing even beginners to use text-to-speech easily.

Common Problems with AI Text-to-Speech Services and Solutions

We introduce common problems encountered when using AI text-to-speech sites and free software, and their solutions.

Solutions for When Pronunciation Becomes Unnatural

In this case, it can be resolved by adding furigana to the kanji or re-entering it in hiragana.

Ondoku is equipped with a function to specify how kanji are read, so you can achieve accurate pronunciation!

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

What Should I Do When the Audio Quality is Poor?

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

Services like Ondoku that adopt the latest AI technology are capable of more natural vocalization.

With installed software, audio quality may drop if the computer specs are low.

In that case, it is recommended to use an install-free browser-based service that performs processing in the cloud.

What if Installation or Access to the AI Service Doesn't Go Well?

If you cannot install download-type software, check the settings of your security software.

Also, since it is possible that the OS is not supported, it is important to check the system requirements.

If you cannot access an install-free browser-based service, trying a different browser is one solution.

With a cloud-based service like Ondoku, you can avoid installation problems.
