Introducing Kuaishou Kling V1 AI Avatar Pro on WaveSpeedAI

Kling AI Avatar Pro Now Available on WaveSpeedAI: Transform Any Portrait into a Lifelike Talking Video

The era of accessible, high-quality AI-generated talking avatars has arrived. WaveSpeedAI is excited to announce the availability of Kling AI Avatar Pro, Kuaishou Technology’s powerful audio-driven portrait animation model that transforms a single image into a realistic talking-head video synchronized perfectly with your audio.

Whether you’re creating marketing content, educational videos, product explainers, or virtual host presentations, Kling AI Avatar Pro delivers professional-grade results without the traditional costs and complexity of video production.

What is Kling AI Avatar Pro?

Kling AI Avatar Pro is an advanced image-to-video model developed by Kuaishou, the technology company behind the acclaimed Kling video generation platform. This model takes two simple inputs—a portrait image and an audio file—and produces a fully synchronized talking-head video complete with natural lip movements, facial expressions, and subtle head motion.

Unlike basic lip-sync tools that simply animate mouths, Kling AI Avatar Pro creates genuinely lifelike performances. The model has been trained on thousands of hours of curated video footage featuring performers with clear emotional ranges and natural gesture patterns, resulting in outputs that feel authentically human rather than artificially generated.

The model supports multilingual content out of the box, having been trained on data from Chinese, English, Japanese, and Korean sources—making it immediately practical for global marketing campaigns and international content strategies.

Key Features

High-Fidelity Lip Synchronization: Phoneme-aligned lip movements that match your audio with precision, handling everything from conversational speech to complex singing scenarios with over 90% accuracy
Natural Micro-Expressions: Realistic eye blinks, subtle head movements, and facial expressions that bring static portraits to life
Identity Preservation: Maintains the subject’s appearance, lighting, and characteristics throughout the generated video
Single Image Input: No need for multiple reference photos or complex setup—one clear, front-facing portrait is all you need
Long-Form Support: Generate videos up to 10 minutes (600 seconds) in length, perfect for comprehensive presentations or extended content
Optional Style Guidance: Use text prompts to influence framing, mood, pacing, and background tone
Production-Ready Output: Stable, consistent results suitable for professional deployment

Real-World Use Cases

Marketing and Advertising

Create compelling video advertisements featuring brand ambassadors or product spokespeople without scheduling expensive video shoots. Generate multilingual versions of the same campaign by simply swapping audio tracks—the avatar handles the rest.

Getting Started on WaveSpeedAI

Using Kling AI Avatar Pro on WaveSpeedAI is straightforward:

Prepare Your Portrait: Use a clear, front-facing photo with even lighting and minimal occlusions. Images should be 512 pixels or larger for optimal results.
Prepare Your Audio: Record clean speech at 16–48 kHz with minimal background music or reverb. High-quality microphones or professional TTS services produce the best consonant clarity.

Download Your Video: Receive your synchronized talking-head video ready for immediate use.

Pro Tips for Best Results:

Trim silence from the beginning and end of your audio to optimize timing and reduce costs
For business applications, use neutral backgrounds and consistent headroom across portrait images
Specify emotions or presentation styles in your prompt (e.g., “speaking enthusiastically” or “professional presentation style”) for more tailored animations
