Summary of recommended text reading software. 7 selections that can be used for commercial purposes [Free/Paid]

Do you know about text reading software?

Text-to-speech software is software that converts documents such as text and characters into audio and reads them out loud .

In addition to reading in Japanese, we also have products that support multiple languages such as English, Chinese, German, Spanish, and Italian.

Some allow you to freely change the speed of the audio, and some allow you to download audio files such as .mp3.

You may think, "I'll never have a chance to use that kind of software."

However, text reading software is much more familiar than we think.

Furthermore, more text reading software has been developed and sold for various purposes than there were two or three years ago.

Even if you think, ``Okay, I'd like to try out some software, I'll look for it,'' but there are many software that aren't well-known, and it can be difficult to find software that suits your tastes in the vast ocean of the Internet.

This time, we will introduce a total of 7 recommended text reading software, both free and paid versions.

Many of the recent text-to-speech software read text very smoothly and sound like a human voice. The audio is also available for immediate viewing. Please check it out!

Many people want to try out text reading software, but don't feel comfortable spending the money to buy one.

For those people, we will start by introducing free software.

text talk

"Text Talk" uses the free text-to-speech synthesis system "Open JTalk."

I recommend using it to the extent that it's okay if you can use it for free.

  • Multilingual: Japanese, English
  • Commercial use: possible
  • Operating environment: Windows 8, Windows 7, Windows Vista

text talk


This is a tone of voice that is commonly called ``slow''.

It sounds like a mechanical sound, but it's not easy to hear. However, if there are subtitles underneath, you can hear it somehow, and I can't help but think it's unique.

Although it is free software, it allows detailed settings, such as being able to fast forward and rewind text line by line.

Regarding commercial use, some restrictions may be set by the provider of the speech synthesis engine/library. Be sure to check.

  • Tuning: Possible
  • Audio: 28 people
  • Multilingual: Japanese, English
  • Commercial use: Some possible
  • Operating environment: Windows 10, Windows 8, Windows 8.1, Windows 7, Windows Vista


stick reader

Bar Reader is software that incorporates AquesTalk.dll, which is the same as the voice of Soft Talk.

It uses the same engine and has the same sound quality as Soft Talk.

It seems that you are using an older version of AquesTalk (for Win), so commercial use is possible.

It sounds like a mechanical sound, but it's not easy to hear. However, if there are subtitles underneath, you can hear it somehow, and I can't help but think it's unique.

  • Tuning: Possible

  • Multilingual: English

There are many different types of text reading software!

As I researched it, I was surprised at the amount of software available.

What surprised me even more was that text-to-speech software is now being used for a variety of purposes.

  • A service that lets you read all the daily news in just 5 minutes.
  • Used for narration in the program "Moyamoya Summers 2"
  • Used as a YouTube voiceover

It has become a very familiar presence.

There are also some software that we were not able to introduce here. I will introduce that software on another occasion.

I would be happy if you read blogs other than this article and watch Youtube!

Well, I look forward to seeing you again.
