A talking character is one of the most effective devices in game marketing — and one of the most expensive to produce. Traditional lip animation means rigging, keyframing, or motion capture for every line, which makes spoken-character content impractical for the volume and iteration speed UA and social teams need.
Lip Sync on Layer turns any audio or speech track into accurate mouth movement. Bring a character clip and a voice line, and Layer drives the character's mouth to match — no rigging, no keyframes. Pair it with text-to-speech or cloned voices and the entire pipeline, from script to speaking character, lives in one workspace.
Key Capabilities
Audio-driven mouth animation Provide any audio or speech track and Layer syncs the character's mouth to it. Dialogue, narration, or a punchy ad hook — the character delivers the line convincingly.
Pairs with text-to-speech Write the line, generate the voice with Layer's text-to-speech, and lip-sync it in the same workspace. Script changes become regenerations, not reshoots.
Works with cloned voices Use voice cloning to give a recurring character a consistent, recognizable voice, then drive every new line through Lip Sync so the character always sounds — and moves — like themselves.
From generated or existing footage Apply lip sync to clips generated inside Layer or to footage you bring in, so both new AI content and existing character assets can speak.
One platform, full pipeline With 149+ AI models across image, video, 3D, and audio — including video models like Veo 3.1, Seedance, Kling, and Wan — you can generate the character, the clip, the voice, and the sync without switching tools.
How It Works
Prepare your character clip Generate a character video in Layer or upload existing footage of the character who will deliver the line.
Add the voice Upload recorded audio, or create it in-platform: type the script into text-to-speech, or use a cloned voice for a consistent character sound.
Sync and review Layer animates the mouth to match the track. Review the result in your workspace, swap lines or voices, and regenerate until the delivery lands.
Built for Game Production
Character-led UA creatives Talking-character ads are a proven UA format. Lip Sync lets performance teams produce spoken variants at test velocity — new hooks, new lines, new voices — without an animation backlog.
Cutscene-style content Produce narrative beats where characters actually deliver dialogue, for trailers, story recaps, and community content, at a fraction of traditional animation effort.
Localization at scale Re-voice the same character clip for each market: generate the localized line with text-to-speech, lip-sync it, and ship regional variants from one master asset.
Live-ops announcements with personality Let your mascot or hero announce the new event, season, or update on social and in-game channels — speaking content that would never fit a manual animation budget.
Layer is trusted by 300+ game studios and entertainment brands, including Zynga, SciPlay, Huuuge Games, and Machine Zone. Start free and hear your characters speak their first line.
