【Frequently Asked Questions】
Q. Does Ondoku use Generative AI?
A. Generative AI (LLM: Large Language Models) is not used in Ondoku's voice service.
The AI in Ondoku's voice creation service generates voices using a speech synthesis engine, and we define this speech synthesis technology as "AI."
Speech synthesis refers to the technology of artificially creating human voices, a technology already utilized in various situations such as announcements on public transportation, automated responses in call centers, and reading electronic books.
Q. Does Ondoku use voice actors' voices illegally or violate their copyrights?
A. No, we do not. Please use our service with peace of mind.
