Kling V2 AI Avatar Pro | AI Digital Human API

Kling-v2-ai-avatar-pro — Talking Avatar from Image + Audio

kling-v2-ai-avatar-pro turns a single portrait into a lip-synced talking-head video driven by your own audio. Upload a clear face image, provide a narration or dialogue track, and the model generates a vertical HD avatar clip that speaks and moves naturally on camera.

🌟 Highlights

Audio-driven performance – Uses your uploaded audio as-is (no TTS), keeping timing, pauses and emotion.
Photo-real talking avatar – Animates the face, eyes and head while preserving the identity from the reference image.
One-shot setup – Just an image + audio; no need for video capture or motion recording.
Portrait-ready output – Produces social-ready vertical video that fits Reels, TikTok, Shorts and story formats.
Prompt-guided styling (optional) – Use prompt to hint at camera feel or mood (e.g. “soft studio lighting, subtle head movement, gentle smile”).

🔧 Parameters

audio* – Required. The voice track that drives lip-sync and timing (URL or upload).
image* – Required. A clear, front-facing portrait of the person to animate.
prompt – Optional text describing style, expression or camera feel. If omitted, the model uses a neutral talking-head style.

Tip: Use a well-lit, unobstructed face (no heavy motion blur, minimal occlusion) for best identity preservation.

🚀 How to Use

Upload audio

Clean mono/stereo track, with minimal background noise.
Make sure the final edited length matches what you want in the video.

Upload image

Front or 3/4 view, eyes visible, face not cropped.
The avatar’s identity and pose come from this image.

(Optional) Add a prompt

Guide expression or style, e.g.:
“confident presenter in a tech promo, subtle head nods”
“friendly customer service tone, warm expression”

Run the model

The video length is automatically derived from the audio duration.
Download the generated talking-head clip and drop it into your editor or directly onto social platforms.

💰 Pricing

Billing is based on audio duration, with a minimum of 5 seconds.

Audio length (s)	Billed seconds	Price (USD)
0–5	5	0.56
10	10	1.12
20	20	2.24
30	30	3.36
60	60	6.72

Any clip shorter than 5 seconds is still billed as 5 seconds.

🧠 Tips for Best Results

Edit your audio first – Remove mistakes, long silences and background noise before upload.
Match tone to use case – Calm, even delivery for corporate avatars; more expressive reads for ads or UGC.
Keep framing consistent – Use images with similar head size and framing across a campaign for a unified look.
Test a few portraits – Small changes in the reference image (lighting, angle) can noticeably change the avatar’s feel.
