Kling 2.6: See the Sound, Hear the Vision
The "silent film era" of AI video generation is officially over.
Earlier Kling models focused only on visual generation, producing "silent pictures." Creators had to rely on a fragmented workflow: generating video, sourcing voiceovers, adding sound effects, and manually adjusting pacing. This process was time-consuming, disjointed, and rarely achieved true immersion.
With Kling 2.6, the gap between visuals and audio is finally bridged. The model generates synchronized visuals, natural speech, matching sound effects, and atmospheric background audio-all in a single pass. Now, whether you start from text or an image, you can produce a fully voiced, rhythmic, and immersive video with just one click.
Core Capabilities: Audio-Visual Synchronization
The Kling 2.6 model introduces a joint generation mechanism in which audio is generated alongside visual data rather than added as a post-processing overlay. This approach delivers three key technical improvements:
- Audio-Visual Sync: Speech rhythm, ambient sounds, and on-screen actions are tightly aligned, avoiding the disconnect where visuals and audio feel out of sync.
- Audio Quality: Supports multiple sound types-including voice, sound effects, and ambient audio-with cleaner output, richer layering, and a result that's closer to professional-grade mixing.
- Semantic Understanding: Demonstrates strong semantic understanding across diverse scenarios, from textual descriptions and conversational language to complex narratives, enabling more accurate interpretation of creative intent and more relevant audio-visual outputs.
Supported Modes
Kling 2.6 offers two primary generation modes on Artflo:
- Text-to-Video: Generates both visuals and audio entirely from text prompts.
- Image-to-Video: Uses an uploaded image as the visual reference (subject and composition) while text prompts guide audio and motion.
Supported Audio Types
The model is trained to handle specific audio categories defined via prompting:
Monologue/Narration
Single character speaking to the camera or voiceover.
Prompt:
- Visual: In a beauty live-streaming room, warm yellow lighting illuminates the table, with lipstick samples displayed on either side.
- Dialog: [Caucasian beauty influencer] raises a matte dusty rose lipstick. [Caucasian beauty influencer, sweet and fresh voice] says: "Perfect for yellow undertones! Brightens the complexion without drying, and the finish looks beautifully soft all day."
- Background: Soft beauty BGM playing.
Multi-Character Dialogue
Multi-turn conversation between two or more characters.
Prompt:
- Visual: In an office area of a New York office building, cool-toned lighting illuminates the workspace, and a printer is running.
- Dialog: [Foreign male employee] and [Foreign female employee] stand next to the printer, facing each other. [Foreign male employee, calm voice]: "How's the project report coming along? Manager needs it this afternoon." During this, [Foreign female employee] remains silent. Immediately, [Foreign female employee, efficient voice] responds: "Almost done. I'll send it in 10 minutes."During this, [Foreign male employee] remains silent. The camera focuses on their interaction, with the sound of the printer and the office background ambiance.
Music
Singing or Rapping (supports lyrics and specific beat styles like Boom Bap or Trap).
Prompt:
- Visual: In a livehouse, bathed in blue light, a high barstool is placed in the center, with the audience hidden in the shadows.
- Dialog: [Short-haired female singer] sits on the high barstool, holding a wooden guitar, her fingers gently strumming the strings.[Short-haired female singer, heartfelt voice] sings: "And I will try to fix you, all night long..." When she reaches the chorus, [Short-haired female singer] looks out toward the audience.
- Background: The sound of clinking glasses. The camera switches between focusing on the short-haired female singer's fingers on the strings and her facial expression.
Sound Effects (SFX)
Action-specific sounds (e.g., footsteps, machinery, breaking glass).
Prompt:
- Visual: A scene in Antarctica with towering ice formations, the overall tone being a cold, white, frigid color palette.
- Dialog: (No characters, just environmental sounds) The glacier cracks with a loud noise, followed by the sound of ice shattering, as the engines of the research team's snowmobiles roar. The camera follows the retreating research team and the collapsing ice towers.
