Why creators pick Fliki for lip sync
Three lip-sync engines, one project
Standalone lip-sync tools are single-engine and stop at the export. Fliki picks the right model per shot, in 30+ languages, with TTS, voiceover, avatars, and translation built into the same editor.
Sync-3 for studio-grade video-to-video
When your input is a real video clip, Fliki routes the job to Sync-3 - the highest-fidelity lip-sync model on the market. Frame-accurate mouth alignment, no "AI mouth" artifacts.
OmniHuman 1.5 for talking-photo from a single still
Upload one photo - portrait, headshot, character art, mascot - and OmniHuman 1.5 generates a fully animated talking photo with synced lips, head motion, and natural micro-expressions. No video footage needed.
PixVerse for fast portrait sync
When you need a quick sync on a portrait clip, PixVerse delivers in under a minute. Right pick for high-volume social and ad iterations where speed beats max fidelity.
Lip sync in 30+ languages
Most lip-sync tools were trained on English mouth shapes and fall apart in other languages. Fliki’s pipeline handles 30+ languages with native-language phoneme accuracy - critical for global ad localization, multilingual dubbing, and educational content.
Pair with 2,000+ AI voices
Skip the voiceover artist. Pick from 2,000+ neural voices in 80+ languages with our text to speech engine, or upload a 30-second sample to clone your own voice and sync it to any face.
Translate and re-sync in one click
Combine with our video translator to re-dub any video into 80+ languages and re-sync the speaker’s mouth automatically. The fastest path to fully localized international ads.
Animated captions on the same project
Burn TikTok-style word-by-word animated captions onto the lip-synced video without leaving the editor. The full social-ready pipeline lives in one project.
Portrait, square, and landscape supported
Output works in 9:16 for Reels and TikTok, 1:1 for LinkedIn, and 16:9 for YouTube. Resize the same video without re-syncing or re-rendering.
Includes Sync-3 - what sync.so sells as a standalone product
sync.so charges separately for the Sync-3 model. Fliki includes Sync-3 alongside OmniHuman 1.5 and PixVerse, with TTS, voiceover, AI avatars, captions, and translation built in. Start free instead of paying for Sync-3 alone.
Watermark-free, commercial-ready exports
Paid plans ship watermark-free 1080p MP4s with full commercial usage rights covering the lip-synced output, AI voices, and avatar appearances.

AI Lip Sync FAQ
Frequently asked questions about AI lip sync
Everything you need to know about generating lip-synced videos with Fliki.
What is an AI lip sync generator?
An AI lip sync generator analyzes audio and automatically animates a face — photo or video — so the mouth movements match the speech. Fliki routes each job to the right model: Sync-3 for video-to-video, OmniHuman 1.5 for talking-photo from a single still, and PixVerse for fast portrait sync.
Can I lip sync a photo (not a video)?
Yes. Upload a single still image and Fliki uses OmniHuman 1.5 to generate a fully animated talking video with synced lips, natural head motion, and micro-expressions. No video footage needed.
What languages does AI lip sync support?
Fliki's lip sync pipeline handles 30+ languages with native-language phoneme accuracy — critical for dubbing, ad localization, and multilingual educational content. Pair with 2,000+ AI voices in 80+ languages for end-to-end multilingual output.
How long does lip sync generation take?
Most clips complete in under 2 minutes. Sync-3 video-to-video runs slightly longer than OmniHuman 1.5 or PixVerse portrait sync, depending on clip length and resolution.
Can I use my own voice for lip sync?
Yes. Upload a 30-second audio sample and Fliki clones your voice, then syncs it to any face. You can also upload a pre-recorded audio file or use any of the 2,000+ built-in AI voices.
Is lip sync output watermark-free?
Paid plans export watermark-free 1080p MP4s with full commercial usage rights covering the lip-synced output, AI voices, and avatar appearances. The free plan includes a watermark.

Start freeWhat is the difference between Sync-3, OmniHuman 1.5, and PixVerse?
Sync-3 delivers studio-grade lip sync on video-to-video inputs with no "AI mouth" artifacts. OmniHuman 1.5 animates a single still photo into a full talking video. PixVerse is the fastest option for portrait clips where speed matters more than maximum fidelity. Fliki picks the right model automatically based on your input.
When is it ethical to use AI lip sync?
Use Fliki Lip Sync only with people who have given explicit consent: your own face, faces of people who have approved the use, AI avatars you generated yourself, or talking-photo of subjects with appropriate rights (deceased family for memorial videos, licensed historical figures, your own brand mascots). Do not use lip sync to impersonate real people without consent. FTC endorsement guidelines, the EU AI Act, and most platform terms require disclosure when AI-generated likeness or speech is used in advertising or testimonial contexts. Fliki adds an optional "AI-generated" watermark for use cases where disclosure is required.
Can I add captions to the lip-synced video?
Yes. Burn TikTok-style word-by-word animated captions onto your lip-synced video without leaving the editor. The full captioning pipeline is built into the same Fliki project.
