About me
I'm Kozy, and I provide Japanese voiceover services, AI training & Japanese business support. You can find my Japanese AI voice on the major AI voice websites such as ElevenLabs. In addition, I participated at xAI as a sound engineer for AI training, and at Outlier as a Japanese AI trainer in 2025.
I've worked with various companies and YouTubers, and I've even been in anime. For example, I did the Japanese dub for the latest Angry Birds animation, Mystery Island. I also run a Japanese voiceover agency called Just Global Media. We can arrange voice talent of all ages and genders.

Worked well to localize my ad in a language I don't understand well. He was able to rephrase to fit the pace of the video while sounding natural
