Kling Video 3.0 Omni Audio: Native Lip Sync & Multilingual Voices

Kling VIDEO 3.0 and Kling VIDEO 3.0 Omni support Native Audio, bringing dialogue, sound effects, ambience, and visual performance into supported video generation workflows.

Setting Up Your Character Elements with Voice

For reference-driven character work, begin with clean character references and a clear speaker plan. Kling VIDEO 3.0 Omni supports video element reference and element voice control, helping visual identity and voice direction stay connected in supported workflows.

For scenes built around recurring characters, prepare clean character references and clear dialogue instructions before generation. The goal is to make each speaker easy to identify and keep the speaking role connected to the correct character.

1.  Video Element Reference: Use a 3-8 second character video when the workflow needs visual and audio characteristics captured from video reference.

2.  Element Voice Control: Add voice to elements when the workflow needs the speaking voice to stay connected with a character element.

Once the character and voice relationship is set, keep the prompt direct. Name the speaker, write the line, and describe the intended emotion or delivery so the performance has a clear target.

Writing Scripts for Native Audio and Lip Sync

Kling VIDEO 3.0 and Kling VIDEO 3.0 Omni support Native Audio, with dialogue, sound, and lip movement designed to work together inside the generation.

Writing Speaker Instructions Clearly

For multi-speaker scenes, identify the speaker plainly in the prompt and use the available voice controls where the workflow needs a specific speaker or voice tone.

A clean script works better than a complicated structure. Keep each speaker's line close to the character name, and add delivery notes such as whispering, surprise, hesitation, or a low voice only when they matter to the scene.

Creating Realistic Soundscapes

Beyond dialogue, Native Audio can include sound effects and ambience that match the scene. For a daily-life scene, describe the acoustic environment plainly, such as an indoor living room with a subtle air-conditioner hum.

Pair acoustic details with the visual action. A prompt can include dialogue, tone, ambient room sound, weather, or other scene sounds when those details support the story.

Prompt

Output

Korean high school rooftop scene with distant city lights and subtle wind sounds in the background while stars twinkle in the night sky; the female lead leans against the railing dazing as the male lead approaches with two cans of cola and hands one to her, which she takes and opens; the male lead says in a relaxed tone, “숙제 다 했어? 왜 여기 있어?”; the female lead sighs and says, “시험이 너무 무서워.”; the male lead says gently, “걱정 마, 넌 잘할 거야.”

Tutorial: Designing Multilingual Conversations

The current series supports Chinese, English, Japanese, Korean, and Spanish, along with authentic dialects and accents.

Step-by-Step Multilingual Code-Switching

The model supports dialogue in different languages within the same scene. Follow these steps to produce a bilingual conversation for work or daily life:

1.  Select Character Elements: Choose two subjects with different bound voices.

2.  Define the Script: Write a prompt where each character responds in their respective language. For instance, a Japanese boy might ask a question in Japanese, and a Japanese girl might respond in the same language or a different one.

3.  Keep Speaker Lines Clear: Put each speaker's name, line, and delivery note close together.

4.  Describe the Delivery: Add emotional markers like "whispers," "exclaims," or "responds in a low, flat voice."

Lip movements and facial expressions should remain natural and coherent across supported languages and accents, making global dialogue scenes feel more believable.

Indoor home environment with a subtle background hum of a living room air conditioner for realistic daily life; the mother exclaims softly with a tone of surprise, “Wow, I didn’t expect this plot at all.”; the father responds in a low, flat voice, “Yeah, it’s totally unexpected, never thought that would happen.”; the boy says cheerfully, “It’s the best twist ever!”; the girl nods excitedly, “I can’t believe they did that!”

Tips for High-Fidelity Lip-Sync Performance

Strong lip-sync performance depends on clear dialogue, visible faces, and readable delivery notes.

● Emotional Delivery: Describe visible expression and delivery, such as a smile, surprise, sadness, whispering, or a low voice, when those details matter.

● Visible Face and Framing: Keep the speaking face readable when lip movement and expression matter to the scene.

● Clean References: When creating a character element, verify the audio reference has no overlapping voices or loud music. A clean signal provides the model with a clear ground truth for the voice tone extraction.

● Script Simplicity: Simpler grammar often leads to better results. Break complex sentences into shorter dialogue lines to help the model maintain a natural rhythm.

Clear scripts, clean references, and direct speaker descriptions help dialogue scenes feel more natural and easier to review.
