LinguaLink - Realtime Translations

LinguaLink is an open-source, AI-powered translation desktop application built with Kotlin Multiplatform and Compose. It enables real-time bilingual conversations by connecting three AI services in a seamless pipeline: your voice is captured by the microphone, transcribed to text using Deepgram's streaming ASR (nova-3 model), translated into the target language by a serverless LLM hosted on AMD's Fireworks AI infrastructure, and then converted back into spoken audio using Deepgram's Aura-2 TTS voices — all within seconds. Beyond voice calls, LinguaLink also supports text-based chat translation with the same AI backend. It supports 13 languages including Arabic, Chinese, Urdu, Hindi, Japanese, Spanish, and more. Every session — whether a voice call or a text chat — is automatically saved to a local SQLite database with a full transcript, so users can revisit and replay past conversations at any time. Built for the AMD AI Hackathon, LinguaLink demonstrates how AMD-hosted open-source LLMs on Fireworks AI can power production-quality, latency-sensitive language applications on the desktop — with no cloud lock-in and full local data ownership.
