Kling 数字人生成器 - Veemo AI

Use a well-lit, front-facing headshot where the face occupies at least 40% of the frame. Avoid heavy shadows, extreme angles, or occluded features like sunglasses. A neutral expression with the mouth closed gives the model the cleanest baseline for animating speech. Resolution of 512x512 or higher is recommended — lower-resolution inputs still work but may lose fine detail around the eyes and lips.

The model achieves millisecond-precision alignment between mouth shapes and audio phonemes. It maps visemes (visual mouth positions) to the audio waveform rather than relying on simple open/close cycles, so consonant clusters and rapid speech remain convincing. Accuracy holds across languages with different phonetic structures, including tonal languages like Mandarin where mouth shape and timing differ from English.

MP3, WAV, and AAC files are all accepted. You can also type a text script and let the built-in TTS engine generate the voice track. For best results with uploaded audio, use clean recordings with minimal background noise and a consistent speaking pace. The model handles audio up to 5 minutes in length for extended avatar performances.

Kling Avatar generates natural eye contact, eyebrow raises, head tilts, and upper-body gestures automatically based on the audio tone and pacing. You do not manually keyframe these — the blueprint planning system analyzes the full audio track before generation and maps expressive beats to appropriate moments. The output includes 1080p resolution at 48fps, giving smooth motion that holds up on large screens.

Yes. The lip-sync engine is language-agnostic because it operates on audio waveforms, not text transcription. It performs well with English, Mandarin, Spanish, Japanese, Korean, Arabic, and other widely spoken languages. Tonal and syllable-timed languages receive the same phoneme-level precision as stress-timed languages like English.

Common enterprise deployments include localized training videos where one portrait generates presenters speaking dozens of languages, e-commerce product explainers that swap scripts without reshooting, and internal communications where executives record a script once and the avatar delivers it with consistent energy. The 5-minute duration ceiling covers most corporate video formats without splitting into multiple clips.
