Kuaishou Kling 2.1 launches synchronized sound effect function, competing with Google Veo 3 in AI video generation​

Mars Finance News: According to Decrypt, the Chinese short-video platform Kuaishou has recently upgraded its AI video generation tool Kling 2.1, adding a synchronized sound effect generation feature that can automatically add environmental sounds like footsteps and rain. The feature supports video generation at 1080p resolution, with a single generation time of 5 to 10 seconds, and is currently available for free. In terms of pricing, the Kling 2.1 subscription is $9 per month, which is over 20 times lower than Google Veo 3's $250 monthly fee. Tests show that Kling stands out in environmental sound synchronization and cost advantages, but does not currently support voice synthesis; Veo 3 maintains a technical lead in voice generation and complex sound effect processing. Notably, Kling 2.1 has unique features like "adding sound effects to silent videos" and "lip-sync", while Veo 3 only supports text-to-video generation. In content moderation, Kling adopts a relatively relaxed strategy, whereas Veo 3 implements a strict keyword filtering mechanism.
