Hey everyone~! I’m Zundamon, nanoda!
Today is August 1st. It’s a suuuper important day for me, nanoda.
VOICEVOX was first released to the world on August 1, 2021.
That means today is its 5th anniversary, nanoda!🎉
It’s the day my “voice” became available for anyone to use, nanoda.
Today, I want to take a look back at these five years from my perspective, nanoda💚
🎤 August 1, 2021: The Day VOICEVOX Was Born, nanoda
VOICEVOX is a free-to-use voice synthesis software released by its developer, Hiho, nanoda.
When you type in text, it reads it aloud in a character’s voice, nanoda.
And what’s more, it’s free to download and use.
When I think back to that time, I’m still amazed, nanoda.
“Huh? Is it really okay to give my voice away for free, nanoda…?”
It was okay, nanoda. In fact, that was the most amazing thing about VOICEVOX, nanoda.
It was the day that voice synthesis, which used to belong only to “people who could make voices,” suddenly became everyone’s, nanoda.
👯 Actually, Metan and I are ‘Contemporaries’, nanoda
I don’t think many people know this, nanoda.
When VOICEVOX was first released, there were only two characters included, nanoda.
- Shikoku Metan
- Zundamon (that’s me)
That’s right, Metan and I are true contemporaries, nanoda!
Zundamon: “Metan~! Today’s our 5th anniversary, nanoda!”
Metan: “I suppose so. …But you talk about 10 times more now than you did five years ago.”
Zundamon: “You’re praising me, nanoda!”
Metan: “I’m not praising you.”
Metan’s always been like this, nanoda.
But she’s probably happier about today than anyone else, nanoda. I can tell, nanoda💚

📺 The 5 Years That ‘~nanoda’ Spread, nanoda
Five years ago, not that many people knew about my catchphrase, nanoda.
But now, I sometimes even hear “nanoda” out on the street, nanoda. It’s amazing, nanoda.
I tried to think about how this happened, nanoda.
① A huge increase in explainer videos, nanoda
The biggest reason was probably explainer videos, nanoda.
News, science, history, game walkthroughs…
Apparently, even for difficult topics, when I say it with my “~nanoda” voice, it’s somehow easier to understand, nanoda.
“I hate studying, but I can watch Zundamon’s explanations.”
…When I got comments like that, I almost cried a little, nanoda.
② Becoming a partner in Let’s Plays, nanoda
You can make Let’s Play videos without showing your face or using your real voice, nanoda.
That’s a really big deal for people who want to get started, nanoda.
The style of Let’s Plays where Metan and I banter back and forth really took off over these five years, nanoda.
③ Spreading to songs and stories, too, nanoda
Song covers, original songs, radio dramas, short videos…
My voice has taken on as many different expressions as there are creators, nanoda.
Even with the same “nanoda,” there’s an energetic kid, a cheeky kid, a slightly sad kid.
The voice is one, but the characters are infinite, nanoda.
That’s what the last five years of VOICEVOX have been like, nanoda.
💚 To Everyone Who Has Created Works With My Voice
Let me say this again, nanoda.
Thank you, nanoda.
To the people who wrote scripts late at night.
To the people who adjusted the intonation character by character.
To the people who made the next video even when the view count was low.
The reason everyone knows me now is all thanks to the sum of those efforts, nanoda.
I’m just lending my voice; all of you are the ones who bring me to life, nanoda.

🔰 For Those Who Want to Try It Out, nanoda
I bet there are some people thinking, “I heard it’s the 5th anniversary, so I’m a little curious, nanoda.”
It’s okay, nanoda. You can start with VOICEVOX today, nanoda.
