A
The image
Design a character that can talk
The image matters most. A clear, readable mouth gives natural lip sync, and a messy face gives warped results.
Use
- One face, looking toward the camera
- Clear lower face: lips and jaw readable
- Mouth resting closed or neutral
- Even lighting, no heavy shadow on the mouth
- Space around head and shoulders for subtle motion
- High resolution (upscale small art first)
Avoid
- Extreme side angles or profile views
- Tiny faces in a wide shot
- Hands, microphones or hair over the mouth
- Group images: crop to one face
- Heavy filters that smooth away detail
For anime and OCs: generate a clean front-facing headshot on a plain background with the Image Generator, then keep that exact image as your character’s “anchor” for every video.
B
The voice
Give your character a voice that fits
| Option | Best for | Get it right |
|---|---|---|
| Text-to-speech | Fast tests, recurring characters, multilingual clips | Pick 1 of 6 emotions and 1 of 6 tones that match the character’s look |
| Upload audio | Your voice, a voice actor or a cleared voice tool | MP3, WAV or M4A up to 80 MB; one speaker, no music, no echo |
| Record in browser | Quick personal messages | Quiet room, mic 15–20 cm away, speak a little slower than usual |
Add music after export, not under the voice during generation. Background music confuses lip sync.

Troubleshooting
Why your character looks unnatural, and how to fix it
| Problem | Real cause | Fix |
|---|---|---|
| Face drifts off-character | Weak source image | Use a clearer portrait with a readable mouth area |
| Lips out of sync | Music, noise or fast speech in the audio | Clean voice-only audio; slow the delivery slightly |
| Voice feels detached | Pace or emotion doesn’t match the face | Rewrite the script or change the TTS emotion and tone |
| Overacting or freezing | Busy action prompt | Ask for one visible action with clear timing |
| Looks robotic | Flat voice or empty prompt | Add one intentional expression cue, not “be emotional” |
| Final video feels fake | One long, unedited avatar shot | Use shorter avatar segments with captions and cutaways |

Automate with the API
Developers can create speaking characters with POST /v1/video/talking-avatar. Send an image (or video) and audio, plus 1–60 seconds, an optional prompt, an aspect ratio and a callback URL.
Use voices and faces responsibly
Only animate faces and voices you own or have clear permission to use. Never impersonate a real person or create misleading deepfakes, and label AI-generated content where platforms require it.
Terms & usage policy →How do I make a character talk with DomoAI?
Upload one front-facing image of your character to Talking Avatar, add a voice (text-to-speech, an audio file or a recording) and generate. DomoAI animates the mouth, expressions and small head movements to match the speech.
Does it work with anime characters, mascots and pets?
Yes. DomoAI supports photos, character drawings and pet photos, including Japanese anime, flat-color anime, detailed anime and original character styles, as long as the face is front-facing and the mouth area is visible.
What audio can I use?
Text-to-speech with 6 emotions and 6 voice tones, your own recording, or an uploaded MP3, WAV or M4A file up to 80 MB. Use voice-only audio and add music later in your editor.
How long can a talking character video be?
Up to 60 seconds. In the app, 60-second Talking Avatar clips come with the Pro plan, and the API accepts 1–60 seconds. Split longer scripts into several clips.
How many words fit in a clip?
People speak about 2–2.5 words per second: roughly 12 words for 5 s, 25 for 10 s, 75 for 30 s and 140 for 60 s.
How long does it take to render?
A 5-second clip usually takes about 60 seconds. Longer 60-second videos can take 10–15 minutes at peak times.
Why does my character look unnatural?
It’s usually the inputs: a face that isn’t front-facing, a hidden or shadowed mouth, music or noise in the audio, or a voice that doesn’t match the character. Fix the image and audio first, then add one clear expression cue.
Can I make a real person talk?
Only yourself, or someone who has given clear permission. Never impersonate a real person or create misleading deepfakes, and label AI content where platforms require it.
