How to Use Cute Voices in Ondoku? Explaining the Tips

From here, we will explain the tips for creating cute children's voices with Ondoku!

Among reading software, Ondoku has a rich variety of cute voices.

You can choose widely from cute female voices to cute children's voices.

Why not create a cute voice with Ondoku, which can be used just by accessing it from your browser for free and without installation?

"Mayu (Female)" is Perfect for a Cute Female Voice

If you want to use a cute female voice, please try choosing "Mayu (Female)."

Among Ondoku's female voices, it is a reading voice that gives a particularly gentle and cute impression.

Because elegance and cuteness are perfectly balanced, it is easy to use for business purposes while still having a cute impression, making it a highly recommended voice.

"Aoi (Child/Girl)" is Best for a Child's Voice

If you want to read in a cute child's voice, "Aoi (Child/Girl)" is ideal.

With a cute voice just like a real child, it is a reading voice perfect for educational content and children's videos.

You can utilize a child's cute voice for various purposes, such as explanations in YouTube videos, store announcements, and turning educational materials into audio.

"Robot (Female)" is also Recommended for Character Videos

For anime-style content and character videos, why not try "Robot (Female)" as well?

You might imagine mechanical audio from the name "Robot," but it can actually read aloud in a very cute female voice.

It goes well with anime-style content and can be used for creating videos using cute character illustrations.

The key point when using it is to keep the audio pitch at 0 (unadjusted).

Points to Consider when Adjusting the Reading Speed

Speed adjustment is also important when using cute voices in reading software.

To produce a child-like way of speaking, a slightly slower speed setting is recommended.

In the case of Ondoku's child voice "Aoi," setting the speed to about 0.8 to 0.9 times is effective.

Since children often speak more slowly than adults, setting it to this speed can reproduce a child's cute voice.

Additionally, for educational content and learning materials, a slow speed of about 0.7 to 0.9 times is ideal.

Conversely, for entertainment content, a standard speed (1.0x) or a slightly faster setting (1.1x) is effective.

When making YouTube videos, you can grab the viewer's attention by adding narration at a good tempo with a cute voice.
