When you want to convert text into speech, AI-powered text-to-speech sites and software are extremely convenient.

Recently, the number of high-quality AI text-to-speech services available for free has increased, and many services that are easy to use without installation have emerged.

In this article, we will introduce in detail the latest free AI text-to-speech sites and free software for 2026.

We will introduce the best options for various purposes, such as services that allow commercial use and those that can read aloud with natural voices, so please use this as a reference.

What is an AI Text-to-Speech Service? Detailed Explanation of Basic Knowledge

AI text-to-speech is a technology that converts text into speech using artificial intelligence technology.

Compared to conventional mechanical text-to-speech, AI-powered reading has natural inflection and intonation, making it possible to generate audio that sounds as if a human is speaking.

In particular, recent AI text-to-speech technology has evolved rapidly, and even free services can now generate high-quality audio.

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

There are two types of text-to-speech sites: those that can be used directly from a browser and those 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 easily utilize text-to-speech.

Points to Consider When Choosing a Free AI Text-to-Speech Site

Here are some points to consider when choosing a free AI text-to-speech site or free software.

1. Ability to Read with a Natural Voice

First and foremost, the naturalness of the voice is important.

Services utilizing the latest AI technology allow for reading with more natural inflection and intonation.

Next to consider is whether it can be used directly from a browser without installation.

Installation-free services have the advantage of being immediately available from any device and generating high-quality audio regardless of computer specifications.

2. Is it Free? What are the Functional Limitations of the Free Version?

It is also necessary to check the number of characters that can be used for free and any functional limitations.

Even among free services, some allow commercial use while others do not, so it is important to choose according to your needs.

Furthermore, whether it supports multiple languages is also an important point.

Choosing a service that supports not only Japanese but also multiple languages such as English, French, German, Spanish, Korean, and Chinese allows for a wider range of applications.

3. Check Security for AI Services

Even for free AI text-to-speech sites, security cannot be ignored.

Especially when using it for work, it is recommended to choose a service where the operator is clearly stated and trustworthy.

Additionally, choosing a service that properly protects your account, such as by offering two-factor authentication during login, is also key.

What are the Points for Using AI Text-to-Speech Services/Sites for Free?

AI text-to-speech sites and free software sometimes have limitations on their free versions.

Here we introduce how to understand and use these limitations wisely.

Free AI Services/Sites May Have Limitations

In many free services, there is a limit on the number of characters that can be read at one time.

Caution is necessary because some services have a low number of characters that can be read for free.

Ondoku is Recommended for Free AI Text-to-Speech!

When you want to read a lot for free, Ondoku is recommended!

How to Wisely Bypass the Limitations of Free Versions

Even for services that require credit notation, there is no problem as long as it is properly stated in the video's end credits or elsewhere.

Particularly, let's effectively utilize high-quality free services with few limitations like Ondoku!

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

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

How to Solve Problems When Pronunciation Becomes Unnatural

Because Japanese kanji have multiple readings, it may not result in the intended pronunciation.

In this case, the problem can be solved by adding furigana to the kanji or re-entering the text in hiragana.

Ondoku is equipped with a function to specify the reading of kanji, so you can achieve accurate pronunciation!

Since technical terms and proper nouns are particularly prone to misreading, we recommend checking them in advance.

What Should I Do When the Audio Quality is Poor?

If 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 allow for more natural speech.

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

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

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

If downloadable software cannot be installed, check the settings of your security software.

Also, because the OS may not be supported, it is important to check system requirements.

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

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