How to Dub a Video in Another Language — The Easy Way | Perso AI

To dub a video in another language, upload it to Perso AI, select your target language from 33+ options, and the AI handles translation, voice cloning, and lip-sync automatically — in minutes, not days.

Perso AI is an AI dubbing platform used by 460,000+ creators and teams worldwide, starting at $6.99/month. This guide walks through the complete process, from upload to export.

Why Creators Are Switching to AI Dubbing

Traditional video dubbing requires five separate steps: hire a translator, book a voice actor, record in a studio, edit the audio, and manually sync lip movements. For a single 10-minute video in one language, this process can take one to two weeks and cost several hundred dollars.

AI dubbing collapses this into a single automated workflow. Perso AI translates the script, clones the original speaker's voice, generates the dubbed audio, and syncs lip movements — all from one upload. The result: up to 98% reduction in dubbing cost compared to traditional methods, with processing times measured in minutes rather than weeks.

Perso AI now serves 460,000+ users across more than 80 countries, with 80% of its user base located outside South Korea — a direct signal of where global demand for AI dubbing is growing. Dubbed content reaches audiences more effectively than subtitles alone, especially on mobile and short-form platforms where reading while watching creates friction.

Step-by-Step: How to Dub a Video in Another Language with Perso AI

Perso AI is an AI-powered dubbing and video localization platform that automates voice cloning, translation, and lip-sync in a three-step workflow. Here is the complete process:

Step 1 — Upload Your Video

Go to Perso AI and upload your video file directly, or paste a link from YouTube, TikTok, Instagram, or any hosted video URL. You do not need to re-download content that is already published.

Step 2 — Select Your Target Language

Choose from 33+ supported languages including Spanish, Mandarin Chinese, Hindi, Arabic, French, Portuguese (Brazilian and European), Russian, Japanese, German, and more. You can run the process multiple times from the same source video to create versions for different markets.

Step 3 — Export Your Dubbed Video

Once AI processing is complete, download the finished video in standard formats compatible with YouTube, TikTok, Instagram, LinkedIn, and corporate platforms. You can also export separate audio tracks and .srt subtitle files for platforms that support multi-language audio.

What the AI does automatically:

• Transcribes the original audio

• Translates the script to the target language

• Generates a voice-cloned voiceover that matches the original speaker's tone and pitch

• Applies AI lip-sync to align mouth movements with the new audio

What Makes AI Dubbing Different: Voice Cloning vs. Generic TTS

Perso AI uses voice cloning technology, not generic text-to-speech. The distinction matters.

Generic TTS produces a standardized voice that sounds mechanical and detached from the original speaker. Voice cloning captures the original speaker's tone, pitch, pacing, and emotional delivery — so the dubbed version sounds like the same person speaking naturally in the new language.

Taehyun Kim, Director of PUBG: BATTLEGROUNDS, describes his experience with Perso AI: "As part of our effort to connect with our English-speaking players, we used Perso AI to dub my voice into English. Thanks to its amazing translation and lip sync capabilities, we were able to communicate with global users more directly and authentically."

For marketers, educators, and creators, this means branded content retains the presenter's identity across every localized version — without re-recording.

Advanced Features for Power Users

Perso AI offers full manual control beneath its automated workflow, making it suitable for professional production pipelines.

Multi-Speaker Detection — Perso AI automatically detects and processes up to 10 distinct speakers per video. Each speaker receives their own voice clone in the target language. This makes the platform practical for webinars, panel discussions, corporate meetings, and educational content with multiple instructors.

Script Editor — Before finalizing the dubbed output, review and edit the translated script directly inside Perso AI. This ensures cultural references, brand terminology, and regional phrasing match the target audience's expectations.

Social Media Link Translation — Paste a TikTok or YouTube Shorts link directly into Perso AI — no need to download the video first. Perso AI processes the source URL and returns the dubbed version ready for re-upload.

Taeksoon Kwon, CTO at ESTsoft (Perso AI's parent company), describes the platform philosophy: "One click to dub, full control underneath. Perso AI makes the simple path effortless while giving power users access to every layer — subtitles, scripts, separated audio, and more."

Traditional Dubbing vs. AI Dubbing: Side-by-Side Comparison

Before AI dubbing tools existed, localizing a single video required a multi-vendor workflow. Here is how the two approaches compare:

The core advantage of AI dubbing is not just speed — it is the elimination of each manual handoff between translation, voice recording, and lip-sync editing that creates both delays and quality inconsistencies in traditional workflows.
