What is a Text-to-Speech Tool?

A text-to-speech tool is software that converts documents such as text and characters into audio and reads them aloud.

The audio is not someone speaking in real-time, but a generated machine voice.
Due to recent improvements in AI technology, machine voices are now capable of very natural text-to-speech. If you haven't tried it yet, please give it a try right now! You will surely be surprised, thinking, "Is this really a machine voice?"

Is Downloading a Text-to-Speech Tool Mandatory?

Text-to-speech tools are developed, sold, and distributed by multiple companies.

  • Those that must be downloaded and installed on a computer
  • Those that can be used in a web browser and on smartphones or computers
  • Those that can be used via smartphone apps

There are various types available.

Text-to-speech tools do not necessarily require a download, so it is best to find a tool that suits your purpose.

If you cannot choose a voice that suits your preference, it can become tiring to listen to or simply not match your taste.

Especially when used for narration, many people tend to prefer:

  • Female voices

Main factors include ease of hearing and a comfortable pitch range.

For Japanese audio in Ondoku, a total of 16 types of voices are available, including male voices, female voices, and children's (girls') voices.

You can also choose the pitch (high/low) and change the speaking speed, allowing you to adjust settings to your preference.
