Perso AI

What is Perso AI?

Perso AI (branded Perso Dubbing) is built by ESTsoft, a South Korean software company founded in 1993, and specializes in dubbing existing video into other languages rather than generating avatars from a script. It clones the original speaker's voice and tone into 99+ languages, syncs lip movement to the new audio at a claimed 98.5% accuracy, separates dialogue from background audio and music, and includes speech-to-text and subtitle-script editing.

ESTsoft is an official ElevenLabs partner, pairing that voice technology with its own lip-sync and localization pipeline. The company also offers Perso Interactive (real-time interactive avatars) and STUDIO PERSO (AI avatar video production) as separate products under the same brand.

Key features

• Voice cloning that preserves the original speaker's tone across 99+ languages
• Frame-level AI lip-sync claimed at 98.5% accuracy
• Automatic separation of dialogue from background music/noise before re-dubbing
• Speech-to-text and an in-browser subtitle/script editor
• Voice cloning included on every paid plan (no separate add-on fee)
• REST API for programmatic, large-scale dubbing workflows

How to get started

1. Upload the video you want dubbed
2. Select the target language(s) from 99+ supported options
3. Let Perso clone the speaker's voice and sync new audio to lip movement
4. Edit the auto-generated script or subtitles if needed
5. Export the dubbed video, or automate the pipeline via the API

Perso AI pricing

Starter costs $6.99/month for about 7 minutes of dubbing (420 credits), roughly a quarter of comparable avatar-based tools' entry price, with voice cloning included at no extra cost. Creator costs $29/month for about 40 minutes, and Pro costs $99/month for about 180 minutes; Enterprise pricing is custom for unlimited usage.

Our take: By preserving the real presenter on screen and cloning their actual voice, Perso positions itself against avatar-first tools like Synthesia and HeyGen as the choice for localizing existing footage rather than generating new talking-head video.
