Discover Step Audio Edit X—the groundbreaking open-source AI audio model that brings lifelike, emotionally expressive voice generation straight to your local machine. In this video, we walk through everything: from installing the model with ComfyUI, voice cloning with zero-shot capability, to applying dynamic emotional edits like “humor,” “happy,” or “whisper” to your AI-generated speech. You’ll also see how to integrate it into AI talking avatar workflows using WAN Video 2.2 and Infinite Talk for seamless lip-synced videos.
