Clone a voice and create talking avatar videos using Anthropic and deAPI

Who is this for?

- Content creators who want a consistent on-screen avatar without filming themselves - Marketing teams producing personalized video messages at scale - Educators building video lessons with a virtual presenter - Anyone who wants to turn text into a talking avatar video using a cloned voice

What problem does this solve?

Creating a talking-head video normally requires a camera, lighting, and a person on screen. Voice cloning adds another layer of complexity. This workflow handles everything — provide a short voice sample and an image, type what you want the avatar to say, and get a lip-synced talking avatar video.

What this workflow does

1. Reads a short reference audio clip and a first frame image in parallel 2. Clones the voice from the reference audio using deAPI (Qwen3 TTS VoiceClone) and generates new speech from the provided text 3. Merges the cloned audio and the first frame image into a single item 4. AI Agent crafts a talking-avatar-optimized video prompt — focusing on lip sync, facial expressions, and natural movement — then boosts it with the deAPI Video Prompt Booster tool using the first frame image for visual context 5. Generates a talking avatar video synced to the cloned speech using deAPI (LTX-2.3 22B), with the image as the opening frame and the AI-crafted prompt guiding the scene
