Frequently asked questions
Can I dub Portuguese videos to Japanese for free?
Yes. Spimov's free plan lets you dub your first Portuguese 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.
How accurate is the Portuguese to Japanese translation?
Spimov uses large language models for context-aware translation — adapting idioms and meaning rather than word-for-word — then aligns the Japanese audio to the video timing.
