## 🎬 What is GeoTalk?

GeoTalk is an AI-powered geoscience podcast generator that turns your geological data into an engaging debate between AI scientists — complete with **animated 3D robot avatars**, **text-to-speech voices**, and **live captions**.

Upload a core photo, well log, or outcrop image, and watch two AI geoscientists (plus a moderator) debate the interpretation in real-time.

**Pipeline:**
1. **Vision Analysis** — Qwen2.5-VL-72B describes the uploaded geological image
2. **Script Generation** — Qwen2.5-72B writes a multi-character debate script (with Chair)
3. **Text-to-Speech** — Edge-TTS generates distinct voices for each character
4. **Live Viewer** — Three.js renders animated robots synced to audio playback

## 🚀 Quick Start

## 🤖 Robot Avatars

The 3D robot avatars are inspired by [Reachy Mini](https://huggingface.co/spaces/build-small-hackathon/small-talk) from the Small Talk project. They feature:

- **Procedural Three.js geometry** — no external model files needed
- **Per-speaker animations** — talking (head bob, antenna wiggle), listening (head tilt), idle (gentle sway)
- **Visual feedback** — active speaker panel highlighted with colored border
- **Chair indicator** — center panel with pulsing microphone icon

## 🛠️ Tech Stack

- **Frontend:** Three.js, Gradio, HTML5 Audio
- **LLM:** Qwen2.5-72B-Instruct (script generation)
- **Vision:** Qwen2.5-VL-72B-Instruct (image analysis)
- **TTS:** Edge-TTS (Microsoft Neural voices)
