Audio Generation is the use of AI to create sound, including music, voiceover, sound effects, and ambient audio, from text prompts or other inputs. It is one of the fastest-growing areas of AI creative tools, allowing creators to produce fully custom audio content without recording equipment, musicians, or voice actors.

AI audio generation models are trained on large libraries of sound and music, learning the patterns and structures that distinguish different genres, instruments, moods, and voice types. Given a text description such as "upbeat electronic background music for a product demo" or "a calm female narrator with a British accent," these models can generate audio that closely matches the description. Leading audio AI tools include ElevenLabs for voice synthesis and models like Veo 3 and Sora 2, which can generate synchronised audio alongside video.

For AI filmmakers and content creators, audio generation removes one of the most significant remaining barriers to fully AI-produced content. The ability to generate voiceover, music, and sound effects without licensing or recording costs makes it possible to produce polished, broadcast-quality output entirely within an AI-assisted workflow.
