Lip Sync
Maps speech audio to mouth movements at the phoneme level, producing natural and believable lip articulation synchronized to the provided audio track.
Kling
AI Avatar Standard
Kling AI Avatar Standard is an audio-driven talking-head model developed by Kling that animates a single still portrait image into a synchronized speaking video. It accepts a portrait photo and an audio track as inputs, then generates a video with phoneme-aligned lip movements, natural eye blinks, and subtle head motion while preserving the subject's identity throughout. The model supports both real voice recordings and text-to-speech generated audio, and an optional text prompt can influence background style or framing. Output duration is variable and determined by the length of the provided audio, up to a maximum of 10 minutes. Kling AI Avatar Standard is designed for everyday production workflows where reliable, clean avatar video is needed at scale. Typical use cases include explainer videos, customer support avatars, internal training materials, and product demonstrations. For best results, the model expects a clear, front-facing portrait with even lighting and at least 512px resolution, paired with a clean voice recording sampled at 16–48 kHz. It is available via API through WaveSpeed and is accessible on MindStudio without requiring separate API key management.
