AI Video Models with Audio & Sound: 17 Compared
Which AI video models generate native sound? Compare dialogue, sound effects, and music generation across 17 models.
Most AI video generators produce silent clips, requiring you to add sound effects, music, and dialogue in post-production. But a growing number of models now generate native audio alongside the video, including synchronized sound effects, ambient audio, and even spoken dialogue. This comparison covers the 17 AI video models that support audio generation.
Veo 3.1 and Veo 3.1 Lite from Google, Seedance 2.5 and Seedance 2.0 from ByteDance, Sora 2 Pro from OpenAI, Grok Imagine Video 1.5 from xAI, FLUX.3 Video from Black Forest Labs, and LTX 2.5 from Lightricks cover premium audio-video workflows. PixVerse V6, Vidu Q3, Kling, and LTX 2.3 cover a range of lower-cost workflows.
On Melies, audio generation is available as an option when using supported models. Generate with and without audio to compare; credit pricing follows the selected model and settings.
