Dub Chinese Videos to Japanese
Turn any Chinese video into natural Japanese with AI voice cloning, lip sync and subtitles — in minutes, not weeks.
Spimov automatically transcribes your Chinese audio, translates it into Japanese with context-aware AI, and re-voices it in a cloned version of the original speaker. The result is a Japanese dub that sounds natural and stays in sync with the video.

Why dub from Chinese to Japanese?

What to watch for in Japanese
Japanese mixes three scripts and uses levels of politeness that change the tone of a line. Spimov's translation keeps a neutral-polite register by default; if your content needs a casual or formal read, adjust the transcript before re-voicing.
Where Japanese dubbing gets used
Japanese is common for anime-adjacent content, gaming videos, product manuals and corporate training.
Japanese audience and market
Japanese audiences are used to high production values in dubbing, so it is worth reviewing the transcript rather than shipping the first pass.
Spimov supports dubbing across 600+ languages. Learn how AI dubbing works or jump straight in — your first video is on the free plan.

Frequently asked questions
Does the Japanese dub use polite or casual speech?
The default translation sits at a neutral-polite register that works for most content. Politeness carries real meaning in Japanese, so review the transcript and adjust lines that should be more casual or more formal, then re-voice those segments.
Can I dub Chinese videos to Japanese for free?
Yes. Spimov's free plan lets you dub your first Chinese video into Japanese with AI — no credit card required. Paid plans add more minutes, lip sync, and remove the watermark.
Will the Japanese dub keep the original speaker's voice?
Yes. Spimov clones the original speaker's voice, so the Japanese version sounds like the same person and preserves tone and emotion instead of a generic voice.
