What does zatsune mean?

"Zatsune" is not a recognized word in Japanese. It's likely a misspelling of "Hatsune", which is the first part of the famous vocal synthesizer's name, Hatsune Miku.

Here's why it's likely a misspelling:

* Hatsune means "first sound" in Japanese.

* Miku means "future" in Japanese.

Together, Hatsune Miku represents the "first sound of the future", which is fitting for a vocal synthesizer that allows users to create music with a virtual singer.
