📖 What is VOICEVOX (Zundamon)?

Free text-to-speech and singing voice synthesis software. It comes with over 47 character voices — including Shikoku Metan, Zundamon, and Kasukabe Tsumugi — and can turn typed text into natural-sounding speech. You can fine-tune intonation, accent, and speaking speed, and it even includes a "humming" feature that makes the voice sing. It runs on Windows, Mac, and Linux, and is great for reading out stream chat, narrating game commentary, or making videos. It's free for both commercial and non-commercial use, but since each character has its own terms of use, be sure to check them before using.

💡 When to Use It

Great for automatically reading out chat comments in the voice of a popular character like Zundamon during your stream. It saves you the trouble of reading comments yourself, and the character's voice adds liveliness to your stream. Pairing it with OneComme (a chat viewer) makes setup easy.
