XTTS v2Voice CloningLLMPPTXFastAPIAgentic Coding

A document-to-deck studio: paste a document or a prompt, let an LLM draft the outline and slides, then narrate every slide in a cloned voice. It turns a rough brief into a presentable deck — and an auto-narrated walkthrough video — in one pass.

Walkthrough narrated end to end by my fine-tuned XTTS v2 voice — no human voiceover.

What it does

The voice

Narration runs on an XTTS v2 model I fine-tuned for a target speaker. Cloning takes a short reference clip; the studio caches voice embeddings so repeat narration stays fast. Every word in the video above is synthetic.

How it was built

Built in about a week with an agentic-coding workflow — AI coding agents driving the implementation under close review — across the generation, slide-editing, voice, and export layers. The fine-tuned XTTS v2 model is the piece that makes the narration sound like a specific person rather than a stock TTS voice.
