PERSO.ai

Take a ten-minute English video and turn it into a Spanish or Korean version that keeps the speaker's own cloned voice and matches lip movement.

That is the core job of PERSO.ai, an AI dubbing tool that also works as a video translator, subtitle generator and speech-to-text service with speaker detection.

It supports 32+ languages and claims 98% translation accuracy, and a Cultural Intelligence Engine is meant to handle nuance rather than word-for-word output.

Dubbing covers clips from 5 seconds to 30 minutes, while the AI Studio video creation side goes up to 50 minutes.

PERSO.ai detects multiple speakers automatically and lets you edit the script as you go.

Voice technology comes through a partnership with ElevenLabs.

The vendor says quality beats HeyGen by 32%, which is its own comparison, so test it on your footage.

There is a freemium plan, but free exports carry watermarks and credits and video length are limited.

Enterprise pricing means contacting sales.
