Perfect dialogue without manual keyframes
Upload a voice track or type a script, and Domo AI analyzes every sound and shapes your character’s mouth to match automatically. Works on photos, avatars, anime art and video clips.
It’s DomoAI’s automatic lip-synchronization engine. It analyzes the phonemes (individual speech sounds) and timing in your audio, then adjusts the character’s mouth shapes vowels, consonants and the transitions between them so speech looks natural. No frame-by-frame animation needed.
Lip Sync Auto Match runs underneath these DomoAI workflows.
The audio is broken into phonemes the individual sounds of speech with precise timing.
Each phoneme is matched to a viseme: the mouth shape that produces it (closed for M/B/P, round for O/U…).
Transitions between shapes are smoothed so the mouth moves naturally, not robotically.
The face is animated frame by frame, keeping the character’s look and expression.
| Your voice | Upload a recording (MP3, WAV, M4A) or record in the browser |
|---|---|
| Text-to-speech | Type a script and pick a voice and emotion |
| External voices | Audio from voice tools such as ElevenLabs |
| Songs | Vocals for music videos clean vocal stems work best |
Key rule: the mouth must be clearly visible and not covered by hands, hair or a microphone.
A clear, front-facing image or clip with the mouth visible.
A recording, TTS or external file voice only, silence trimmed.
Talking Avatar, Talking Photo or the AI Video Lip Sync Quick App.
Add the visual and the audio; lip sync is applied automatically.
Check timing on “p”, “b” and “m” before rendering everything.
Download at 1080p, or upscale to 4K.
Most sync problems come from the audio, not the video. Run through this checklist before you upload.
Commentary, explainers and reactions with a character host.
Animated characters singing your track.
Re-sync clips to voiceovers in other languages.
Talking mascots and presenters for lessons and onboarding.
Traditional lip sync means animating mouth shapes by hand, phoneme by phoneme. Auto Match does that in minutes.
| Aspect | Manual | Auto Match |
|---|---|---|
| Time | Hours per minute of dialogue | Minutes |
| Skill | Animation & phoneme knowledge | None |
| Consistency | Varies by animator | Consistent |
| Fine control | Every frame | Limited |
| Re-dubbing | Start over | Swap the audio |
Never use lip sync to impersonate someone, create deepfakes or put words in a real person’s mouth. Get consent before syncing a real person’s face or voice, and be transparent about AI use label it where platforms require.
Terms & usage policy →It’s DomoAI’s automatic lip-sync engine. It analyzes the sounds and timing in your audio and shapes a character’s mouth to match no manual keyframing. It powers the Talking Avatar, Talking Photo and AI Video Lip Sync tools.
Your own recordings (MP3, WAV, M4A), text-to-speech from a typed script, audio from external voice tools, or songs. Clean, voice-only audio gives the most accurate sync.
Yes. It works on real photos, avatars, anime art and stylized illustrations, as long as the mouth is clearly visible. Very heavy stylization can look slightly less natural.
Usually because of the audio: background music or noise, silence at the start, fast mumbled speech or echo. Clean the audio, trim the silence and keep one speaker at a time.
Test with 5–10 seconds first. In the Talking Avatar tool, clips run up to about 60 seconds depending on your plan. Split longer dialogue into segments.
Only with their consent. Never use lip sync to impersonate someone or create misleading deepfakes, and label AI-generated content where platforms require it.
