How to use cute voices in Ondoku for reading? Explanation of tips
From here, we will explain the tips for creating cute children's voices with Ondoku!
Among reading software, Ondoku has an abundant variation of cute voices.
You can choose widely from cute female voices to cute children's voices.
Why not create cute voices with Ondoku, which is free, requires no installation, and can be used just by accessing from a browser?
If you want a cute female voice, "Mayu (Female)" is perfect
Pitch: 0
Pitch: 10
Pitch: -10
When you want to use a cute female voice, please try selecting "Mayu (Female)".
This is a reading voice that gives a particularly gentle and cute impression among Ondoku's female voices.
Since elegance and cuteness are exquisitely balanced, it is easy to use for business purposes and yet has a cute impression, making it a particularly recommended voice.
For children's voices, "Aoi (Child/Girl)" is the most suitable
Pitch: 0
Pitch: 10
Pitch: -10
For reading with a cute child's voice, "Aoi (Child/Girl)" is most suitable.
With a cute voice like a real child, it is the best reading voice for educational content and videos for children.
You can utilize cute children's voices for various purposes such as YouTube video explanations, store announcements, and audio for teaching materials.
"Robot (Female)" is also recommended for character videos
Pitch: 0
Pitch: 10
Pitch: -10
For anime-style content and character videos, why not try "Robot (Female)"?
From the name "Robot", you might imagine mechanical audio, but it can actually read with a very cute female voice.
It has a good compatibility with anime-style content and can also be used for video production using cute character illustrations.
The key point when using it is to set the voice pitch to 0 (unadjusted).
Points for adjusting 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.
Children often speak more slowly than adults, so this speed can reproduce a cute child's voice.
Also, for educational content and learning materials, a slow speed of about 0.7 to 0.9 times is optimal.
Conversely, for entertainment content, standard speed (1.0x) or slightly faster (1.1x) settings are effective.
When making YouTube videos, you can attract viewers' attention by putting in narrations at a good tempo with a cute voice.
