aksharakuppy-transliteration

Aksharakuppy — Manglish → Malayalam Transliteration IME

A character-level Transformer + frequency-dictionary hybrid that converts romanized Malayalam (Manglish) into Malayalam script, with Google-IME-style word suggestions.

Model

• 4-layer encoder-decoder Transformer, ~16.6M params, character-level tokenization
• Hybrid: ~677k-word frequency lexicon (trie prefix lookup) + neural fallback for out-of-vocabulary words
• Trained from scratch on a custom corpus + AI4Bharat Aksharantar (Malayalam) + Google Input Tools corrections

Usage

​python from ime import IME ime = IME("checkpoints_ime") print(ime.suggest("dhoni")) # ['ധോണി', ...] print(ime.suggest("keralam")) # ['കേരളം', ...] ​

Web demo

​bash pip install torch fastapi uvicorn uvicorn server:app --host 0.0.0.0 --port 8000 ​

Limitations

• Ambiguous romanizations may return multiple valid words; the intended word is usually in the top 5.
• Coverage reflects the training lexicon; rare or new words use the neural fallback.
