Unlike traditional text-to-speech systems that only read words aloud, Seed Audio understands the full spectrum of sound. It can generate speech, music, sound effects, ambient atmospheres, and multi-speaker dialogue from a single text prompt. ## What Seed Audio 1.0 is good at * **Multi-modal audio generation**: Speech, music, sound effects, and ambient audio from one prompt. Describe what you hear, and Seed Audio produces it * **Voice cloning**: Clone voices from up to 3 reference clips (tagged `@Audio1`, `@Audio2`, `@Audio3` in the prompt) for multi-character dialogue or consistent narration * **Preset voices**: Pick from built-in TTS 2.0 voices when you need reliable, high-quality narration without a reference clip * **Image-driven voice**: Derive a voice from a character image, matching the tone and style to the visual subject * **Fine-grained control**: Adjust speech rate, pitch, loudness, and sample rate independently for each generation * **Multi-speaker dialogue**: Name characters inline in the prompt and Seed Audio handles voice assignment, turn-taking, and emotional delivery * **Up to 2 minutes per run**: Generate extended audio clips suitable for narration, podcast clips, video dubbing, and sound design With these capabilities, Seed Audio 1.0 fits a wide range of use cases including video voiceovers, multi-character audio dramas, product demos, e-learning narration, game audio prototyping, and accessibility content. ## Use it in ComfyUI Run the text-to-audio, voice cloning, and image-driven audio workflows in ComfyUI, locally or on Comfy Cloud
