The Digital Inequity Facing
17+ Million Sinhala Speakers
Sinhala is a morphologically rich, insular Indo-Aryan language. Despite over 17 million speakers across Sri Lanka and a global diaspora, modern generative AI tools critically fail in grammatical fidelity.
Complex Orthography
54 characters, 18 vowel signs, complex ligatures (බැඳි අකුරු), and strict classical Sidath Sangarawa Natwa/Latwa rules.
Frontier LLMs Fail
Generic LLMs hallucinate false grammatical rules, cost significant compute, and average high latency (1,400ms).
The Solution Needed
A deterministic, explainable, lightweight engine executing in under 15ms with 100% adherence to classical grammar.
Symbolic NLP & The Historic Breakthrough:
Nominative Agent Precedence (NAP)
Overcoming the century-old 'False Plural Hal-Na' polysemy bottleneck that previously hindered all South Asian language computational tools.
- ✓ Finite-State Transducers: Zero-hallucination deterministic parsing.
- ✓ 75,000-Lemma Lexicon: Fast in-memory Tri-Trie search with Sandhi clitic decomposition.
- ✓ Sidath Sangarawa Rules: Phonotactic Natwa/Latwa verbal base disambiguation.
Words like දුන් (relative verbal participle 'given') or අසුන් (inanimate seats) were historically misclassified as plural human subjects, breaking Subject-Verb Agreement.
