The Challenge

International students miss critical lecture content because real-time translation tools are either too slow, inaccurate, or not designed for academic contexts. Existing solutions fail to handle technical vocabulary and produce translations with unacceptable delays.

The Solution

Created a specialized platform using Soniox for high-accuracy speech-to-text and Gemini 2.5 Flash for context-aware academic translation with under 2-second latency. The system is purpose-built for lecture environments, handling technical terms and academic language with precision.
