About VOICEVOX
Free, commercial use included: character voices like Zundamon, on your own computer.
VOICEVOX is free speech and singing synthesis software for Windows, Mac and Linux. It has more than 30 voice characters, such as Zundamon (ずんだもん), plus VOICEVOX Nemo with no character, and lets you edit intonation in detail. It is not a cloud service: the editor and the engine run on your own computer, so there is no sign-up or payment. The engine (VOICEVOX ENGINE) is distributed as an executable and a Docker image, so other software can generate speech with it. Commercial and non-commercial use are both free, but you need a credit line showing VOICEVOX was used, and each character has its own terms.
