Implement Local Transliteration Model #11
Description
Currently, transliteration only supports external AI4Bharat APIs. Implement local transliteration model similar to the IndicTrans2 translation service for better performance, privacy, and offline capability.
Acceptance Criteria
- Research and implement local transliteration model (e.g., IndicXlit, Google Transliteration API, or similar)
- Add environment variables for local model configuration
- Implement dual-mode support (local vs external API)
- Add model loading and caching mechanisms
- Support for major Indian language scripts (Devanagari, Bengali, Tamil, Telugu, etc.)
- Update documentation with local model setup instructions
- Add performance benchmarks comparing local vs external
