Kling
WaveSpeedLip sync video generation from image and audio
AI Avatar Standard is a lip sync model developed by Kling and served through the Wavespeed provider on MindStudio. It takes a portrait image and an audio file as inputs and generates a video in which the subject's mouth movements are synchronized to the spoken audio. Users can also supply a text prompt and select an output resolution, with a seed parameter available for reproducible results.
The model is suited for use cases such as creating talking avatar videos, dubbing static images with voiceover, and producing animated spokesperson content without requiring video footage of the original subject. Pricing is dynamic and starts at $0.28 per second of generated video, making cost proportional to the length of the output clip. It was released in August 2025 and is currently available on MindStudio under the model ID kwaivgi/kling-v1-ai-avatar-standard.
