# Make Your Characters Speak Any Line > Drive a character's mouth from any audio or speech track with AI lip sync. Pair with text-to-speech and cloned voices for character VO. Free to start on Layer. --- 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. ## Frequently Asked Questions ### How does Lip Sync work on Layer?
