How to Read Aloud Using Cute Voices in Ondoku? Explaining the Tips

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

Among reading software, Ondoku has an abundant variation of cute voices.

You can choose from a wide range of tones, from cute female voices to cute children's voices.

Why not try creating cute voices with Ondoku, which can be used for free without installation just by accessing it from your browser?

"Mayu (Female)" is perfect for a cute female voice

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

Among Ondoku's female voices, this reading audio gives a particularly gentle and cute impression.

Because it perfectly balances elegance and cuteness, it is a highly recommended voice that is easy to use for business purposes while still maintaining a cute impression.

"Aoi (Child/Girl)" is best for a child's voice

"Aoi (Child/Girl)" is best for reading aloud in a cute child's voice.

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

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

"Robot (Female)" is also recommended for character videos

Why not try using "Robot (Female)" for anime-style content or character videos?

While the name "Robot" might make you imagine a mechanical voice, it can actually read aloud in a very cute female voice.

It goes well with anime-style content and can be used for video production featuring cute character illustrations.

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

Tips for adjusting reading speed

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

To produce a child-like way of speaking, setting a slightly slower speed 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 allows you to reproduce a child's cute voice.

Additionally, for educational content or learning materials, a slower speed of about 0.7 to 0.9 times is best.

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

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