AI Lip Sync Video Generator that turns your script into a talking ad
Sparkiz is an AI lip sync video generator that makes a lifelike AI actor speak your script with matched mouth movements, then wraps it in a finished ad with voiceover, music, and captions. Lip-sync is strongest in Hebrew, and the English demos here are real examples. You get a ready-to-post MP4 in about 5 to 10 minutes.

What is an AI lip sync video generator?
An AI lip sync video generator makes an on-screen face's mouth move in time with audio. Sparkiz does this with its own lifelike AI actors: pick an actor, it speaks your script with matched lip movement, then wraps it in a finished ad with voiceover, music, and captions. Lip-sync is strongest in Hebrew.
There is an honest distinction worth knowing. Most "lip-sync" tools re-sync the mouth on a clip or photo you upload. Sparkiz works the other way: it generates a lip-synced ad from scratch, with one of its own AI actors speaking a script written from your product. It does not re-dub a video you uploaded or animate a random selfie. If you want the product-first version of this, see a product video with a lip-sync presenter.
How does AI lip sync work?
AI lip sync breaks speech into phonemes, maps each to a viseme (a mouth shape), then animates the actor's mouth to that timing so the words look spoken. In Sparkiz the script and voiceover drive the timing automatically, so the actor speaks your ad copy without a camera or reshoot.
The AI lip sync pipeline: script to voiceover to viseme timing to a synced AI actor.
How to make a lip-sync video with Sparkiz
Four steps, about 5 to 10 minutes, from a product link to a finished MP4.
Add your product
Paste a product link or type the details. Sparkiz uses your photos and copy so the ad is about your product.
Pick an AI actor
Choose from 100+ lifelike actors, or a custom avatar on Growth. This is the face that speaks.
Script, voice, and lip-sync
Sparkiz writes the script and the actor speaks it. On a Hebrew or lip-sync run you get a Review Voiceovers step to check each line before it syncs.
Edit and download
Tweak any line, swap a scene, set captions, then export a 9:16, 1:1, or 16:9 MP4 with full commercial rights.
Lip-sync vs voiceover UGC: which should you pick?
Lip-sync is strongest in Hebrew. For most English ads, voiceover UGC (narration, no mouth-sync) is the reliable default.
Sync the mouth on a clip you upload.
- You supply your own footage or photo
- You get a moving mouth, nothing more
- No product, script, music, or captions
- You still edit it into an ad yourself
Generate a finished lip-synced ad.

Not sure lip-sync is right for your English ad? Voiceover UGC is the safe default. See product video without lip-sync or the AI UGC generator.
What can you make?
A lip-sync presenter, or your own custom avatar that speaks every ad.
Lip-sync presenter
An AI actor speaks to camera and the mouth moves to the words, like a spokesperson. Strongest in Hebrew; the demos on this page are sanctioned English examples. Browse the roster on AI actors.
Your custom avatar
On Growth (3) and Scale (6), build a custom avatar so the same face fronts every ad, and add a matching voice from custom voices.

What languages does the lip-sync support?
Sparkiz supports three languages: Hebrew, English, and Russian. Lip-sync, where the mouth moves to the words, is strongest in Hebrew. The two English clips on this page are real, sanctioned lip-sync examples, but for most English ads a voiceover with no mouth-sync is the more reliable choice.
If you need dozens of languages or video translation, that is not what Sparkiz does. It focuses on native-quality scripts, voice, and captions in these three, rather than auto-dubbing across many.
How much does it cost?
Your first video is a one-time $3, a 35-credit Trial pack for one 15-second video with no watermark. After that a 15-second English video is about 28 credits, roughly $5. Plans are $49, $126, and $252 a month, and captions are always free.

Sparkiz vs a plain lip-sync tool
A plain lip-sync tool syncs a mouth on a clip you upload. Sparkiz generates the whole ad. Here is the honest difference, including where the plain tools win.
| Sparkiz | A plain lip-sync tool | |
|---|---|---|
| What you get | A finished ad: actor, script, voiceover, music, captions | A synced clip, just a moving mouth |
| Who is on screen | 100+ lifelike AI actors (500+ on Growth) | The clip or photo you upload |
| Upload your own footage | Uses AI actors, not your upload | ✓ that is the core input |
| Languages | 3 (EN, HE, RU); lip-sync Hebrew-primary | Varies |
| Voiceover, music, captions | ✓ all three | Usually none |
| Custom avatar | ✓ (3 / 6) | Varies |
| Free / cheap start | $3 one-time, no watermark | Often free to try, or a monthly plan |
| Output | MP4 9:16, 1:1, 16:9, full rights | Varies |
Plain lip-sync tools win if you want to re-dub your own footage for free. Sparkiz wins when you want a finished ad and do not have footage to start from. Want a named head-to-head? See our HeyGen alternative or the full field in best AI UGC tools.
