Prompt

Okay so update — I tried it for a full week and… honestly? I'm not even mad. I went in expecting absolutely nothing, and now I'm three notebooks deep. Like, if you've been on the fence about this — just try it. Trust me on this one.

Prompt

We just shipped something I've been wanting to build for two years. Two whole years. And honestly? I almost didn't. Three rewrites, two pivots, one really bad weekend where I nearly deleted the repo. But it's live now, and it actually works. Go check it out.

Prompt

We started this company with one stubborn belief — that quality is not a feature. It is the whole product. Twelve years in, we have not changed our minds. Not once. Same hands. Same standards. Same promise. That is who we are.

Prompt

The woman speaks naturally to camera with the uploaded audio, subtle head movement and slight sway, occasional casual hand gesture coming into frame mid-sentence, light natural blinks, breaks into a soft smile near the end, raw vlog energy.

Prompt

She slowly lifts the glasses to her face and puts them on as the uploaded audio plays, blinks, tilts her head left and right to check the fit, breaks into a small smile near the end of the line, natural sway, casual unboxing energy, lip-sync to the audio.

Prompt

The founder speaks confidently to camera with the uploaded audio, one calm hand gesture mid-sentence, steady gaze into the lens, subtle natural blinks, brief warm smile at the closing line, polished corporate brand-film energy, locked vertical framing.

Prompt

A young guy in a beanie sits in his car with sunlight streaking across the windshield, looks at his selfie-phone and grins, "Day 47 — and I think I finally figured it out." Slight handheld phone framing, warm afternoon light, casual vlog tone. SFX: the soft hum of the running engine, distant traffic, his quiet laugh, no music.

Prompt

A young Japanese woman on a bustling Shibuya sidewalk turns to camera and answers in clear Japanese, "私の好きな映画は『君の名は』です," then switches to English with a smile, "Have you seen it?" Handheld phone shot at chest height, neon city lights blurred behind. SFX: traffic, footsteps, distant J-pop from a storefront, ambient city.

Prompt

A home cook in a green apron stirs a bubbling tomato sauce on a stovetop, leans toward the camera mounted on a tripod and says casually in Spanish, "El secreto está en la mantequilla — siempre." Bright kitchen window light, raw home-video aesthetic. SFX: the bubble of the sauce, a wooden spoon scraping the pot, kitchen ambience.

Prompt

A creator (lock from reference) sits at her desk in a soft pink sweater, looks at the lens and says in clear Mandarin, "今天我想跟大家分享一个秘密," then smiles. Handheld selfie-phone framing, warm window light, plants and books behind her. SFX: a gentle laugh, soft typing in the background, ambient room tone. Maintain exact appearance from references, no facial drift.

Prompt

A spokesperson (lock from reference) stands in a clean modern office with a city skyline blurred behind through floor-to-ceiling windows, looks into camera, and says in confident German, "Wir verändern die Art, wie Teams arbeiten."

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.

What 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.
