In this article, we will introduce recommended software and sites for reading text aloud.

Since text-to-speech software and sites allow you to save the read content as audio files such as MP3, you can:

  • Use it as narration material for video production
  • Play it as an in-store broadcast on an audio player or smartphone

and utilize it for a wide variety of purposes.

From individual users who want to use it for a hobby to business users who want to use it for shops or companies, why not use this article as a reference to find a text-to-speech software or site that suits your needs?

What kind of software is text-to-speech software?

First, let's briefly explain text-to-speech software and sites.

Features of Text-to-Speech Software and Sites

Features of text-to-speech software and sites

Text-to-speech software and sites are tools or websites designed to load text and read it aloud as audio.

They read aloud based on the input text and can save it as audio files such as MP3 or WAV.

Speech synthesis software has existed for a long time, but previously, only software with robot-like voices existed, where you could immediately tell it was computer-generated.

But now, it's different.

The latest text-to-speech software and sites use AI to synthesize speech, allowing them to read text in clear and realistic voices, just like a professional narrator speaking.

For reading text aloud, we recommend choosing software or sites that use the latest AI.

Benefits of Text-to-Speech Software and Sites

Can read aloud immediately

Can read aloud immediately

Text-to-speech software and sites using the latest AI can read input text immediately.

For example, in the case of 『Ondoku』, it can generate audio for 1,000 characters in just a few seconds and save it as an MP3.

Easier and clearer than reading it yourself

It is very difficult for someone who is not a professional narrator or voice actor to read text aloud, and it is normal for the articulation and pronunciation to be very hard to hear.

In such cases, by using a text-to-speech software or site, anyone can easily read text in clear and easy-to-hear audio.

Also, editing takes a long time.

With text-to-speech software and sites using the latest AI, such trouble is unnecessary.

Good cost performance

You can request a professional narrator or voice actor to read it for you, but it costs a very high fee.

Furthermore, if you request a professional, it also takes time to deliver audio files such as MP3.

In contrast, with a text-to-speech software or site, you can read text for free and save MP3 files immediately.

Dedicated software/sites are recommended for utilizing read audio

Dedicated software/sites are recommended for utilizing read audio

Actually, text-to-speech functionality is standard on iPhone and Android smartphones.

If you turn on the smartphone's reading function from the settings app, it is possible to read the content displayed on the screen.

However, if you want to utilize the read audio for a hobby or work, we recommend using dedicated text-to-speech software or sites.

The reason is that dedicated software and sites can save audio in formats such as MP3.

The standard reading function on smartphones is intended to improve accessibility, so it does not have an audio saving function.

Dedicated software and sites can save audio files as MP3, so it is easy to import them into video editing software or play them as broadcasts on an audio player.

Since there are services like 『Ondoku』 where you can save MP3 files for free, dedicated software or sites are recommended for text-to-speech.
