Try Seed Audio 1.0 in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: bytedance-seed-audio-1-0 ByteDance Seed Audio 1.0 is a text-to-speech and audio generation model served through Fal. It synthesizes natural speech from a text prompt with control over voice, output format, sample rate, speed, volume, and pitch. Up to three reference audio clips can be supplied for voice cloning and referenced in the prompt as @Audio1, @Audio2, @Audio3, or a single reference image can be provided instead.
