Perso AI × ElevenLabs: Official AI Voice Partnership

Update (October 2026): This article describes the partnership as announced in 2025. Perso Dubbing now combines its own dubbing models, including Nightingale, with global AI foundation models.

Perso AI is an official technology partner of ElevenLabs. When the partnership was announced in 2025, Perso AI integrated the ElevenLabs v3 engine as the core voice synthesis layer of its AI dubbing platform.

For content creators, marketers, and enterprises that need to reach global audiences without losing their original voice, the partnership set out to make AI-dubbed voices sound more natural.

What the Perso AI × ElevenLabs Partnership Covered

The partnership focused on voice synthesis, the step in an AI dubbing pipeline that turns a translated script into speech.

At the time of the announcement, ElevenLabs v3 handled that step in Perso AI’s pipeline. When a video was uploaded, the platform performed source separation, script extraction, and translation, then passed the output to ElevenLabs v3 for voice synthesis.

“This partnership puts us at the forefront of next-gen content localization.” — Mati Staniszewski, CEO, ElevenLabs

“Perso AI doesn’t just translate words — it translates cultures.” — Jung Sang-won, CEO, ESTsoft

 The two companies share a foundational belief: that global content should feel like it was made for that audience, not translated for them.

What Is ElevenLabs v3?

ElevenLabs v3 is a voice synthesis model from ElevenLabs. When the partnership was announced, ElevenLabs presented v3 as its most expressive model to date, with improvements in three areas.

Emotional Range: v3 was designed to interpret emotional intent rather than simply read text, so that tone, urgency, warmth, and hesitation follow the context.

Prosody Accuracy: v3 aimed to match the rhythm, stress, and intonation of natural speech in each target language.

Multi-Speaker Fidelity: v3 was built to keep voices distinct and consistent when several speakers appear in the same recording.

For an AI dubbing platform like Perso AI, these were the capabilities the 2025 integration was meant to bring to dubbed video.

How Perso AI Used ElevenLabs v3 at Launch

As described at the announcement, a video processed on Perso AI with ElevenLabs v3 went through these steps:

Step 1 — Audio Separation: Perso AI’s deep-learning source separation isolates speech from background audio, music, and ambient sound with studio-grade precision.

Step 2 — Script Extraction & Translation: The isolated speech is transcribed and translated into the target language, preserving the original speaker’s intent, tone, and contextual meaning.

Step 3 — Voice Synthesis via ElevenLabs v3: The translated script was fed into the ElevenLabs v3 engine, which synthesized a new voice track modeled on the original speaker’s voice.

Step 4 — Lip Sync & Visual Alignment: Perso AI’s frame-by-frame lip sync technology aligns the dubbed audio to the speaker’s mouth movements. Today, Perso Dubbing offers automatic lip-sync on all paid plans, with a monthly lip-sync allowance in each tier.

Step 5 — Export: The final dubbed video — with the original background audio seamlessly reinserted — is ready for export in broadcast-ready quality.

Who Is This Partnership For?

YouTube Creators & Independent Filmmakers Reach new audience segments in Spanish, Japanese, Portuguese, German, and many other languages without re-recording a single line. Perso AI preserves your voice identity across every language, so your channel sounds like you, everywhere.

Enterprise Marketing Teams Scale localized video campaigns without scaling your production budget. A single master video becomes 10, 20, or 30 market-ready assets without agency overhead or studio time.

E-Learning & Corporate Training Deliver onboarding videos, compliance training, and product tutorials to distributed global teams in their native language. Up to 10 simultaneous speakers per video means even panel discussions and multi-host formats are fully supported.

Broadcasters & Media Companies Media teams can dub interviews, panels, and shows with up to 10 speakers per video, and voice cloning keeps each speaker’s own voice in every language.

Perso AI vs. Traditional Dubbing

Traditional video localization involves a chain of vendors: translation agencies, voice talent casting, recording studios, video editors, and QA reviewers. Each step adds cost, time, and the risk of brand voice dilution.

Perso AI collapses this entire workflow into a single platform:

Time: What traditionally takes 2–4 weeks can be completed in hours. A 10-minute video processed through Perso AI takes approximately 10–30 minutes end-to-end.

Cost: Studio dubbing for a single language can run $500–$5,000+ per video depending on length and speaker count. Perso AI’s platform pricing makes multilingual dubbing accessible at a fraction of that cost.

Quality: Perso AI combines its own dubbing models with global AI foundation models, and voice cloning keeps the original speaker’s tone and pacing in each target language.

Consistency: AI-driven dubbing maintains 100% brand voice consistency across every language, every video, every time — something even the best human dubbing teams struggle to achieve at scale.

No matter how great the multilingual content sounds, it will fail to make the right impression with audiences if it’s not synced properly to the presenter. Brands with unique identities struggle to connect when they are forced to switch to an outside presenter. With PERSO.ai’s perfect lip-sync technology, this becomes a thing of the past.

The frame-by-frame analysis of head-on or side-positioned facial and mouth movements allows the AI voice in another language to match with any speaker. In fact, it allows for up to ten per video. With voice cloning and Perso Dubbing’s lip-sync, viewers get an authentic and diverse experience that matches brand intentions.
