| # BharatBhasha AI - Text-to-Speech (TTS) Models Catalog |
|
|
| ## 📌 Repository Purpose & Motivation |
| This repository provides dedicated neural voice synthesis models, VITS checkpoints, and phonetic assets supporting natural offline voice synthesis across **all 22 Official Scheduled Indian Languages + English**. |
|
|
| ### Why this repository exists: |
| 1. **Un-gated Direct Distribution**: Eliminates gating screens, Hugging Face login prompts, or token requirements so mobile (Android) and desktop apps can fetch voices seamlessly. |
| 2. **Hybrid Multi-Engine Architecture**: Provides both dedicated lightweight ONNX models (Piper Neural Voices, ~60 MB) for major languages, and high-coverage VITS models (Meta MMS, ~140 MB) for regional languages. |
| 3. **Phonetic Independence**: Bundles the complete `espeak-ng-data` database and phonetic dictionaries for regional languages (e.g. Sanskrit, Bodo, Santali) so apps operate 100% offline without external system dependencies. |
