Architecture

A low-latency streaming translation system ingested interpreter feeds with Google Cloud Speech-to-Text API, translated and synthesized audio with Cloud Translation API and Text-to-Speech API, scaled through Google Compute Engine and Cloud Load Balancing, and delivered subtitles to users via Firebase. NotebookLM and Gemini Ultra were then used to query and summarize the transcript archive for post-event research and reporting.
