This service is famous for the most natural AI voice synthesis. The voice cloning feature created both buzz and controversy.

This is an AI voice synthesis service run by an American startup that creates voices that are so natural that they are difficult to distinguish from human voices. In addition to the function of reading text, it also provides a voice cloning function that learns and reproduces the voice of a specific person.

It is widely used by creators who create YouTube narration, audiobooks, and multilingual dubbed content. Free usage is provided, but full-scale use is a paid subscription.

Supports multiple languages, including Korean, and the voice cloning function has been the subject of controversy due to concerns about fraud or deepfake abuse.

⚠️ Limits
