In a bright rehearsal room, sunlight streams through the window, and a standing microphone is placed in the center of the room. [Campus band female lead singer] stands in front of the microphone with her eyes closed, while the other members stand around her. [Campus band female lead singer, full voice] leads: "I will try to fix you, with all my heart and soul..." The background is an a cappella harmony, and the camera slowly circles around the band members.
Generate Kling 2.6 AI Video with Voice, Sound Effects & Perfect Lip-Sync
Kling 2.6 is Kuaishou's groundbreaking "Native Audio" AI video model released in December 2025. Unlike previous AI video generators that produce silent clips, Kling 2.6 generates visuals, voice, and sound effects (SFX) simultaneously. This means perfect lip-synchronization, event-matched audio (a glass breaking exactly when it hits the floor), and ready-to-post social media content in one click.
Kling 2.6 is the latest AI video generation model from Kuaishou, launched during their "Omni Launch Week" in December 2025. The biggest innovation in Kling 2.6 is Native Audio—the ability to generate video with synchronized voice and sound effects in a single generation pass.
Before Kling 2.6, creators had to generate silent AI video, then use separate tools like ElevenLabs for voice and other software for sound effects. This workflow was time-consuming and often resulted in poor synchronization. Kling 2.6 eliminates this problem entirely by generating audio and video pixels together, ensuring perfect timing for lip movements and environmental sounds.
Kling 2.6 leads the AI video market in several key areas. Here's why creators and businesses are switching to Kling 2.6 for their video generation needs.
Kling 2.6 generates voice, dialogue, and sound effects simultaneously with the video. No more external audio tools—get ready-to-post TikToks and Reels with complete sound in one click.
Because Kling 2.6 generates audio with the pixels, lip movements match speech perfectly. Environmental sounds sync precisely—a door slams exactly when it closes, glass breaks exactly when it hits the floor.
Kling 2.6 is the "Physics King" for action scenes. Dancing, martial arts, running, fighting—high-motion content that turns other AI models into mush renders beautifully with Kling 2.6.
How does Kling 2.6 compare to Google Veo 3 and OpenAI Sora? Here's the honest breakdown for December 2025.
| Feature | Kling 2.6 | Google Veo 3 | OpenAI Sora |
|---|---|---|---|
| Audio | Native (New) | Excellent Native | Visuals Only |
| Realism | Best for Action & Motion | Best for Cinematic Lighting | Best for Complex Physics |
| Consistency | Market Leader (O1 Library) | Good | Coherent but Less Control |
| Speed | Fastest | Moderate | Slow |
| Best For | Social Media, Action, Stories | TV Commercials, Cinematics | Long-form Simulation |

Everything you need to know about Kling 2.6 AI video generation with native audio.
The biggest upgrade in Kling 2.6 is Native Audio generation. While Kling 2.5 produced silent videos, Kling 2.6 generates voice, dialogue, and sound effects simultaneously with the video. This means perfect lip-sync, event-matched audio, and ready-to-post content without external audio tools.
Kling 2.6 with audio costs approximately double the credits compared to silent generation. A 5-second Kling 2.6 video costs 28 credits without audio and 55 credits with audio. A 10-second Kling 2.6 video costs 55 credits without audio and 110 credits with audio.
Kling 2.6 is known as the "Physics King" because it excels at rendering high-motion content. Martial arts, dancing, running, fighting—scenes that turn other AI models into blurry mush look smooth and natural with Kling 2.6. This is why action content creators prefer Kling 2.6 over alternatives.
