# Ghana Speech-to-Speech Pipeline
A comprehensive pipeline for building multilingual Speech-to-Speech (S2S) AI systems for Ghanaian languages: **Akan (Twi/Fante)**, **Ewe**, **Ga**, and **Dagbani**.
## Architecture
```
+------------------+ +------------------+ +------------------+ +------------------+
| THE EAR'S | | THE EAR | | THE BRAIN | | THE MOUTH |
| TUNER (LID) | --> | (ASR) | --> | (Translation) | --> | (TTS) |
| MMS-LID | | Meta MMS | | NLLB-200 | | XTTS v2 |
+------------------+ +------------------+ +------------------+ +------------------+
```
## Features
- **Automatic Language Detection**: Auto-detect which Ghanaian language is being spoken
- **Multi-language ASR**: Transcribe Akan, Ewe, Ga, Dagbani, and English
- **Cross-language Translation**: Translate between any supported language pair
- **High-quality TTS**: Natural speech synthesis with voice cloning support
- **Full S2S Pipeline**: End-to-end speech translation
- **Web Interface**: Gradio-based demo UI
- **REST API**: FastAPI endpoints for production deployment
## Installation
### 1. Clone the repository
