What it's for

Where Kling AI Avatar shines

Talking avatars

Turn a single character photo and a voice recording into a lip-synced talking-head video.

Voiceover clips

Pair narration audio with a character image to produce a synchronized speaking video up to 15 seconds.

Multilingual delivery

Drive the avatar with audio in different languages thanks to multilingual speech support.

Strengths

  • Audio-driven lip-sync turns one character image plus an audio track into a synchronized talking video
  • Generates image-to-video from a single character photo while preserving the character's identity
  • Two quality tiers: Standard 720p and Pro 1080p, with Pro rendering at 48fps
  • Multilingual speech support per the vendor product page
  • Priced per second of audio, so cost scales transparently with clip length

Trade-offs

  • Requires both a character image and an audio track as input; it cannot generate an avatar from text alone
  • Clip length is capped at 15 seconds per generation
  • Only two fixed quality tiers (720p Standard / 1080p Pro), with no free resolution choice
  • No user-selectable aspect ratio; output is auto center-cropped toward 16:9 or 9:16 based on the input image

About Kling AI Avatar

Kling AI Avatar from Kuaishou is an audio-driven avatar model that brings a single character image to life. Feed it one photo of your talking subject plus an audio track, and it generates a video where the avatar speaks in sync with the audio, preserving the character's identity from frame to frame.

The model offers two quality tiers: Standard at 720p and Pro at 1080p, with Pro rendering at 48fps. Because the audio track drives the lip-sync, the model supports multilingual speech, and clip length follows your audio up to 15 seconds per generation. Output is delivered as an MP4 file, with the frame automatically center-cropped toward 16:9 or 9:16 based on your input image.

On HexGen, pricing is per second of audio and tiered by quality, so cost scales transparently with the length of your clip and the tier you pick. Provide a character image, an audio track, and a short prompt, and Kling AI Avatar handles the rest.
