"කථන" means "speech" or "utterance" in Sinhala — the ancient language of Sri Lanka. It captures our mission: giving Sinhala speech a voice in the age of AI.
Sri Lanka's first conversational AI built specifically for Sinhala speakers. We understand dialects, accents, mixed speech, and the way people actually communicate.
Modern neural speech models adapted for 21 million Sinhala speakers — recognition, synthesis, and real-time conversation in natural Sinhala.
From speech recognition to conversational AI, Kathana is tackling the hardest problems in making voice technology work naturally for Sinhala speakers.
Building robust ASR that works across Sinhala dialects, accents, and mixed-language speech — exactly the way Sri Lankans speak.
Neural TTS that produces fluent, human-like Sinhala voices — culturally natural for real applications across Sri Lanka.
Sri Lanka's first real-time multi-turn voice AI in Sinhala — understands context, holds dialogue, responds naturally.
Curating diverse Sinhala speech data across multiple accents, age groups, and speaking styles to power the next generation of voice AI.
Adapting modern AI — Transformers, Whisper, multilingual LLMs — for the unique characteristics of the Sinhala language and Sri Lankan context.
කථන AI enables a wide range of Sinhala-first applications — from voice assistants to accessibility tools — making technology truly accessible for all Sri Lankans.
AI systems that understand and respond naturally to Sinhala voice commands for everyday tasks.
AI-powered Sinhala call agents handling customer requests naturally and efficiently.
Sinhala voice systems for bookings, appointments, reservations — in the customer's mother tongue.
Voice technology helping all Sri Lankans access digital services — regardless of literacy or ability.
Natural Sinhala voice generation for media, e-learning, and digital content delivery.
Sinhala voice interfaces for Sri Lanka's future technology ecosystem and IoT devices.

Kathana AI (කථන AI) is Sri Lanka's first and best Sinhala AI model — a pioneering Sri Lankan AI research initiative dedicated to Sinhala voice AI, Sinhala speech recognition, and conversational AI for Sri Lanka's 21 million Sinhala speakers. Unlike generic AI models that treat Sinhala as an afterthought, Kathana is purpose-built with deep expertise in Sinhala dialects, accents, and natural speech patterns. Our Sinhala AI research covers automatic speech recognition (ASR), text-to-speech (TTS), and full Sinhala conversational AI — making Kathana the most comprehensive Sinhala language AI in Sri Lanka.
