Talking Avatars AI Generator
Generated on PixelDojo. Produced by PixelDojo's generation pipeline.
Three models here turn a still portrait into a talking clip: P Video Avatar, Kling Avatar and OmniHuman. At their cheapest settings they cost 1, 2 and 3 credits per second of finished video, so a 30 second piece to camera runs 30, 60 or 90 credits. Only one of the three will speak a script you type. The other two need an audio file, and that file sets the length. Every rate, voice count and length cap below was read out of the model configuration files on August 26, 2026.
What each avatar model needs and what it charges
P Video Avatar
1 credit per second at 720p and 2 at 1080p. The only one of the three that accepts a typed script instead of an audio file: it synthesizes the voice itself from 30 named voices across 10 languages. Script length is estimated at 2.5 spoken words per second, and the charge is capped at 60 seconds.
Kling Avatar
2 credits per second on Standard and 3 on Pro. Audio driven, so the audio file decides the output length. The file has to be 5 MB or smaller and billing stops at 60 seconds. Its configuration states it works on realistic humans, stylized characters, cartoons and animals, not only photographic portraits.
OmniHuman
3 credits per second, and it needs both a character image and an audio track. The audio must be under 35 seconds, which puts a hard ceiling of 105 credits on any single job. There is a fast mode that trades detail for speed, plus an optional prompt to steer the performance and a seed for repeatability.
Text to Speech, the track that feeds them
2 credits per 750 words, with a floor of 0.5 credits and a limit of 10,000 characters per request. This is where the audio for Kling Avatar and OmniHuman usually comes from. A 200 word script is 0.6 credits, so the voice is rounding error next to the video.
WAN 2.2 Animate, when the performance is not just a face
2 credits per second at 480 or 720. It drives a character image from a motion reference video rather than from audio, so the whole body moves. Reach for it when the shot needs gesture and posture, not lip sync alone.
Kling Video Character Swap
3 credits per second on Standard and 4 on Pro. It replaces the performer inside footage you already have instead of animating a still. Different job from the three avatar models, same budgeting shape.
VEO 3.1, the no portrait route
The avatar models all start from a picture of a person. VEO 3.1 generates the footage and its own audio together in one pass, with the Fast tier at 3 credits per second. Use it when there is no portrait to animate and the speaker can be invented.
Three avatar models plus the tools that feed them, checked in the files that set the charge. Where a model caps duration or file size, the cap is printed rather than implied.
Why Choose Pixel Dojo for Talking Avatars
Professional-quality results with cutting-edge AI technology
The floor is 1 credit per second
P Video Avatar at 720p is the cheapest talking head here. Thirty seconds of finished video costs 30 credits, and moving to 1080p doubles that to 60.
Only one model reads a script
P Video Avatar takes typed text and speaks it. Kling Avatar and OmniHuman both require an audio file, so with those two you are generating or recording the voice first and paying for it separately.
The length caps differ, and they are hard
OmniHuman refuses audio of 35 seconds or longer. Kling Avatar and P Video Avatar both stop billing at 60 seconds, and Kling also holds the audio file to 5 MB. Plan the script around the shortest cap you might hit.
Budget the video, not the voice
A 200 word script through Text to Speech costs 0.6 credits. The same script as a talking avatar clip runs roughly 80 seconds of speech, which is over a minute of video and the real cost of the job.
How It Works
How to put a talking clip together without wasting credits:
Settle the script and its length first
Speech runs at roughly 2.5 words a second, which is the same rate P Video Avatar uses to estimate its own charge. A 150 word script is about a minute of video, and a minute is exactly where two of the three models stop billing.
Choose the model by input, then by price
If you only have text, P Video Avatar is the one that will speak it. If you already have a recording, all three take it, and the audio length decides the bill on every one of them.
Run it in the app or over the API
Generate from the tool page, or POST the portrait and audio URLs to /api/v1/models/{apiId}/run. Same key and same request shape as every other model, so switching between the three avatar models means changing one string.

Common Questions
Everything you need to know about Talking Avatars
What is the cheapest AI talking avatar model?
P Video Avatar at 1 credit per second of output at 720p, or 2 at 1080p. A 30 second clip at 720p is 30 credits. Kling Avatar is 2 credits a second on Standard and OmniHuman is 3.
Do I need an audio file to make a talking avatar?
For Kling Avatar and OmniHuman, yes, both require one. P Video Avatar is the exception: hand it a typed script and it synthesizes the voice from 30 named voices across 10 languages, or pass audio instead and it lip syncs to that.
How long can an AI avatar clip be?
OmniHuman requires the audio to be under 35 seconds, so 105 credits is the most a single job can cost. Kling Avatar and P Video Avatar both cap billing at 60 seconds, and Kling Avatar additionally holds the audio file to 5 MB.
Will a talking avatar model work on a cartoon or an animal?
Kling Avatar is the one that says so directly. Its configuration describes it as working on realistic humans, stylized characters, cartoons and animals from a single portrait plus an audio track.
What if I need a full body performance rather than a head?
WAN 2.2 Animate at 2 credits per second drives a character image from a motion reference video at 480 or 720, so the body moves with the reference. Kling Video Character Swap goes the other way and replaces the performer inside existing footage, at 3 credits a second on Standard and 4 on Pro.
How do I generate the voice track?
Text to Speech charges 2 credits per 750 words, with a 0.5 credit minimum and a 10,000 character limit per request. Generate the track, then pass its URL to Kling Avatar or OmniHuman as the audio input.
